1. Preface
A multitude of problems related to environmental changes caused by humanactivities and nature itself pose some of the greatest challenges faced by science andtechnology in the 21st century. The Institute of Nature and Environmental Technology,
established in 2002, was reorganised in 2007 to actively tackle such issues. The Instituteplaces particular emphasis on environmental research on the north-eastern fringes of
the continent of Asia with a special focus on areas that touch and encompass the Sea ofJapan. The latter have been shown to be especially vulnerable to global environmental
fluctuations. In 2014, the Institute set itself the objective of addressing the urgent
environmental issues facing the general Sea of Japan area, and of formulating plans fora sustainable environment in the area in the future. Furthermore, in 2016, the Japanese
Ministry of Education, Culture, Sports, Science and Technology designated the Institutean "International Joint Research Center for the Study of Environmental Changes due to
Cross-border Pollution". The Institute has been aiming to make contributions at thedomestic and regional level by examining the Sea of Japan area in particular. To thisend, it has been investigating the origins and quantity of hazardous chemical substances,
the nature of their cross-border transference, and the impact of these substances onhuman health and ecosystems.
The Noto Peninsula, which protrudes into the Sea of Japan, is an ideal observationbase for analysing substances transported across national borders from the eastern
fridges of the Asian continent. Furthermore, the oceanographic condition around thepeninsula is also advantageous to the observation of the movement of harmful chemical
substances. In technical terms, this refers to the recording of fluctuations in the inflow
of substances from the East China Sea by utilising radionuclides as tracers.
In order to take advantage of the location of the Noto Peninsula, the Institute has
set up two atmospheric observation supersites and a marine laboratory on the area. It
has also established the Low-Level Radioactivity Laboratory, which is capable ofmeasuring extremely low levels of radioactivity, as well as the Ogoya Underground
Laboratory. The Botanical Garden there also evaluates organic substances that areharmful to human health. These unique facilities are a major feature of the institute. In
addition, branch offices in China, South Korea and Russia have been set up, in order toestablish overseas collaborative joint research bases.
The Institute, certified as a Joint Usage/Education Center by the Japanese
Ministry of Education, Culture, Sports, Science and Technology in 2012, and re-certified
in 2017 and 2022, has been offering courses that international non-Japanese speaking
students can participate in as well as extensive practical training opportunities for1domestic students. Since receiving “Joint Usage / Research Center” certification in 2016
and then seeing this status renewed in 2022, the institute has been working on researchthat analyses and observes the quantities and transfer characteristics of harmful
chemical substances over a wide area. It has also integrated research that has combined
analyses of the atmospheric, marine, and terrestrial environment aimed at better
understanding the dynamics of the targeted substances in the area. Fig.1

Five years has passes since the last assessment of research and educational activities
in the Institute held in 2017. This short report introduces our activities during the
fiscal year 2017-2021 to help the assessment.

22. Division of Atmospheric Environmental Studies[Ounline]
This division focuses on the atmospheric environment of the Circum-Sea of Japan
area, an area of the world where high concentrations of atmospheric pollutants such as
Asian dust (Kosa: yellow dust) and PM2.5 have become one of the most prominentenvironmental issues. The aim of this division is to clarify their mechanisms ofgeneration, transport, reaction, deposition, ecosystem and human consequences, and tobetter predict future pollution in the area. To this end, this division devises and develops
new analytical methods and fosters joint international research networks. These
activities and their results will make substantial contributions to the global efforts tomitigate atmospheric contamination.
[Monitoring]
Behaviors of Atmospheric Polycyclic Aromatic Hydrocarbons (PAHs) and Nitropolycyclic
Aromatic Hydrocarbons (NPAHs) in East Asian
PAHs are a group of organic compounds consisting of two or more fused benzene
rings, and NPAHs are their nitrated derivatives. PAHs and NPAHs are ubiquitousenvironmental pollutants. Atmospheric PAHs and NPAHs mainly originate fromimperfect combustion and pyrolysis of organic matters, although some NPAHs areformed in the atmosphere via reactions of their parent PAHs such as 2-nitropyrene (2NP) and 2-nitrofluoranthene (2-NFR). In urban areas, PAHs and NPAHs are mainly
emitted from automobiles, power plants, domestic heating and industrial processes.
Many PAHs and NPAHs have carcinogenic and/or mutagenic properties. Benzo[a]pyrene(BaP) and 1-NP are categorized in groups 1 (carcinogenic to humans) and 2A (probably

carcinogenic to humans), respectively (International Agency for Research on Cancer).
Several PAHs also exhibit estrogenic, antiestrogenic, antiandrogenic activities orreactive oxygen species producing activity.
Since 1990s, monitoring of atmospheric PAHs and NPAHs in the East Asian region
has been carried out step by step. So far, we have investigated at 22 urban sites and 3
background sites in Japan, China, South Korea, Mongolia and Russia (Fig. 1). According
to the recent results, the PAHs and NPAHs concentrations in Shenyang, Shanghai(China), and Vladivostok (Russia) highlighted the relatively poor air quality andrelatively high threat to human health compared to those in Sapporo, Sagamihara, andKirishima (Japan). These concentrations in summer were all lower than those in winterexcept for NPAHs concentration in Shanghai. In summer, due to the Pacific Highprevailing, the air pollutants in 6 cities were all affected by clean air masses from theocean to different extents. The PAHs and NPAHs in Japanese cities were mainly emitted3

from domestic Japan and the ocean and could hardly be affected by sources originatingfrom the East Asian mainland. In winter, heating systems were operating in northern
China, leading to the PAHs and NPAHs concentrations in Shenyang increasing sharply.
Moreover, due to the Siberian High prevailing, the air masses (containing many PAHs
and NPAHs) mainly originated from northern China and Mongolia. These polluted air
masses can affect the nearby (Vladivostok) and more distant areas (southern China andJapan), leading to the PAHs and NPAHs concentrations in these cities increasing to someextent. However, local traffic emissions still have relatively large effects. On the other
hand, compared to those in other cities, although the total PAHs and 1-NP
concentrations in Shenyang and Shanghai remained relatively high, they both decreased
notably in recent years because the Chinese government paid more attention toenvironmental protection (Fig. 2.) (Yang et al., Environ. Pollut., 2021).
International networking activities of ground-based observations
Since the establishment of Noto Ground-based Research Observatory (NOTOGRO)
station in Suzu city 10 years ago, it has been home to many domestic and international
collaborations and contributed in more than 20 peer-reviewed publications. To name afew, the NOTOGRO station joined an international campaign to inter-compare theregional cloud condensation nuclei (CCN) characteristics which involved 70 experts from
23 institutions and 14 countries (Schmale et al., Atmos. Chem. Phys., 2018). The aerosolcloud interaction continues to constitute the largest uncertainty in the anthropogenic
radiative forcing on the climate system. The effort to minimizing such uncertainty
requires long-term CCN measurements covering multiple locations and seasons. This
unprecedented dataset was later utilized by a group of 39 researchers across the world
to validate state-of-the-art general circulation and chemical transport model outputs(Fanourgakis et al., Atmos. Chem. Phys., 2019).
Since 2020, the NOTOGRO station also joined a Korean lead project (the center for
Fine Particle Research Initiative in East Asia considering National Differences:
FRIEND) to characterize air pollution in Northeast Asia through a close international
collaboration among four countries (Mongolia, China, Korea and Japan). The FRIEND
project plans to simultaneously measure the air pollutants by deploying high temporal
resolution instruments during intensive field campaigns and conduct modeling studies
for the period of 4.5-years. The first intensive monitoring campaign of PM2.5 and gaseous
pollutants was conducted from December 15, 2020, to January 14, 2021 (Fig. 3). A large
set of measurement data as well as daily filter samples were collected, and analyses are
currently underway. An overview paper from the first intensive monitoring campaign
has been submitted (Kim et al., Atmos. Environ., 2022).

Decreased trend of PM2.5 and BC observed at central and western Japanese islands
Interannual trend of PM2.5 and BC in Noto (Suzu site of the NOTOGRO station)
and Fukue were investigated by using the statistical trend analysis and chemicaltransport model, Regional Air Quality Model 2 (RAQM2ver3). Concentrations of PM2.5
and BC in Noto and Fukue decreased with seasonal variation from 2013 to 2019. Total
reduction of PM2.5 mass concentrations in Noto and Fukue were 7.5 ± 5.0 and 3.8 ± 0.95
μg/m3, which corresponds to 48% and 24% reduction against the initial concentrations,
respectively. The reduction at Noto were larger than those at Fukue. Total reduction of
BC in Noto from 2013 to 2019 were estimated to be 0.13 ± 0.1 μg/m3, and the reduction
account for 32%. Results with the source-receptor analysis by chemical transport model
suggest that decrease of PM2.5 and BC concentrations in Fukue and Noto is strongly
influenced by decrease of transported amount from the Central China, Northern China,
and Japan after 2015/2016. The ratios of PM2.5/BC in Noto indicate that secondary
production of PM2.5 occurs during the transboundary transport and the contribution insummer is larger than those in winter (Fig. 4).
New particle formation in the lower boundary layer by using the kite observation
New particle formation (NPF) is the source of the atmospheric cloud condensation
nuclei. Therefore, these are influence the cloud properties and Earth’s energy balance,
following then changing the atmospheric environment. Based on the ground based
monitoring, the incomplete and weak NPF (starting from ~10 nm) at Fukue island(downstream) are suggesting the nucleation in upstream region. In order to investigate
the NPF, the vertical distribution of atmospheric particle concentrations were observedat remote island, Fukue, by using the UAV. Vertical structure of atmosphericnanoparticle concentration (particle size > 6 nm and altitude < 1.2 km height) during
NPF was observed using UAV at Fukue. Three different type of events were identified
based on aerial observation (different vertical profile of nanoparticles), ground-based
measurement (initial detected diameter of nanoparticle, starting time of NPF, anddominant chemical component in PM1), and air mass backward trajectory analysis. The
stronger NPF event (Event I, > 35,000 # cm-3) with the particle size as small as 5 nm
affected by the long range transport of air pollutants under a high pressure system was
detected. In addition, sudden increase of particle number concentration and SO2
concentration with weak NPF (onset diameter above than 10 nm) caused by the changeof air mass origin (Event II, < 10,000 # cm-3).

[Analytical method]
Development of novel particle measurement techniques
Atmospheric aerosols take variety of mixing states, and various chemicalcompounds are often found to co-exist within a single particle. Such internal mixing
causes large particle to particle variability and significantly affect their fate, behavior
and impacts within the atmospheric environment. There is a constant need for a novel
analytical method capable of sensitively characterizing chemical and physical properties
on a single particle basis.
Raman micro-spectroscopy is used to identify chemical compounds within anaerosol particle, however, its application has generally been limited to supermicronparticles due to the optical diffraction-limit and inherently weak Raman signal. We havebeen working over the years to overcome these limitations by the help of SERS (Surface
Enhanced Raman Spectroscopy) and developed a new condensation-growth coupledsystem capable of detecting sulfate and organics from a single nano-particle as small as
20 nm in diameter (Kunihisa et al., Aerosol Sci. Technol., 2020). This is a significant step
forward in the SERS related work since it pushed the detectable size limit down to wellwithin the Aitken size range, therefore, could even be applied to studying atmosphericparticle nucleation (Fig. 5).
A subset of aerosol particles would act as ice nuclei and thereby play an essential
role in the cloud microphysics and water cycle. However, what makes a good ice nucleus
remained unanswered for many years due to their scarcity. Through our new Individual
Droplet Freezing Method (IDFM), we have demonstrated that atmospheric aging canalter the ice nucleating activity of Asian dust (Iwata and Matsuki, Atmos. Chem. Phys.,2018), and that a certain fungal spore acts efficiently as ice nuclei and emitted selectively
during rainy days (Iwata et al., Atmosphere, 2019).
Mixing of various organic and inorganic compounds can often form core-shell likestructure and its physical properties depend largely on the particle coating. We haveestablished a new method to directly evaluate the adhesion force of individual particles
by using Atomic Force Microscopy (Ono et al., Atmosphere, 2020), and demonstrated thata certain Asian dust particle becomes more adhesive following long-range transport.
[Health effect]
Particulate PAH transport associated with adult chronic cough occurrence closely
connected with meteorological conditions: A modelling study
PAHs are regarded as generating toxic adverse effects on human health. In thisstudy, we analysed the relationship among atmospheric particulate PAHs (p-PAHs),
cough occurrence via epidemiological research, and meteorological conditions using a6

chemical transport model. According to previously reported epidemiological data
observed from 4 January to 30 June 2011 in Kanazawa, a coastal site of the Sea of Japan,
ambient p-PAH exposure is related to chronic cough occurrence in adult patients. Source
receptor relationship (SRR) analysis revealed that a high cough occurrence was causedby exposure to high p-PAH levels in air masses transported from Central China (CCHN,
30-40°N) under westerly conditions. The p-PAHs transported from northern China(NCHN, >40°N) and the eastern part of Russia (ERUS) under northwesterly conditions
also contributed to cough occurrence. The low equivalent potential temperature andgeopotential height anomaly suggested that the p-PAHs emitted near the surface were
suppressed and not transported upward but were instead transported horizontally near
the surface in the boundary layer, resulting in high p-PAH concentrations arriving in
Kanazawa. Our study findings suggest that the air mass transport pattern associatedwith meteorology strongly influences the high p-PAH concentrations causing adultchronic cough occurrence (Fig. 6).

3. Division of Marine Environmental Studies[Outline]
This division studies the influence of harmful chemical substances on marineorganisms and the dynamics of these substances in the marine environment in the
Circum-Sea of Japan area; particularly in coastal areas. This examination of marine
biota is performed through the use of biochemical assays. The research performed aidsin the development of marine environment evaluation systems and for this purpose
involves international collaborations.
To achieve the purpose, we recently focus on the toxicity of polycyclic aromatichydrocarbons (PAHs) on the basis of our basic studies for calcium metabolism. PAHs arewidespread environmental contaminants derived from petroleum and generated throughthe incomplete combustion of fossil fuel, wood, and other organic materials. In theaquatic environment, PAH contamination occurs through storm water runoff.
Atmospheric deposition of PAHs is now the largest source of aquatic PAH contamination.
Furthermore, oil tankers are another anthropogenic source of PAHs and oil spills arecorrelated with the major shipping routes in marine environments. Moreover, accidental
oil spills, such as those from the Deepwater Horizon, the Exxon Valdez, and the
Nakhodka, have caused direct PAH pollution in the marine environment. PAH
contamination is thus prevalent throughout the global marine system and directly affectmarine organisms. In this division, thus, we recently studied the toxicity of PAHs andtheir metabolites in aquatic animals such as fish and sea urchin. We describe below.
[Fish scales as a suitable model for the analysis of pollutants including PAHs on bonemetabolism]
A teleost scale is a bone-like tissue in which coexist osteoblasts (Fig. 1A), osteoclasts(Fig. 1B), and calcified bone matrix. The bone matrix, which includes type I collagen,osteocalcin, osteonectin, and hydroxyapatite, is present in scales as well as inmammalian bone (Ikegame et al., 2019; Kobayashi-Sun et al., 2020). Teleost scales havean important function in regulating blood calcium levels because teleost scales, whichhave both osteoblasts and osteoclasts, are known to function as potential internal
calcium reservoirs similar to those in the endoskeletons of mammals. Using a functional
calcium-regulating organ (teleost scales), we have developed a novel assay system(Honda and Suzuki 2020; Sekiguchi et al., 2021).
Using an assay system, we investigated the influence of PAHs on calcium metabolism.
For example, injecting of BaA (10 ng/g body weight) to nibbler fish (marine teleost)induced both hypocalcemia and hypophosphatemia as a result of inhibition of both
osteoclastic and osteoblastic marker mRNA expressions (Fig. 2) (Zanaty et al., 2020).

[Hydroxylated PAH metabolites cause osteoblast apoptosis and skeletal abnormalities infish]
To study the toxicity of 3-hydroxybenzo[c]phenanthrene (3-OHBcP), a metabolite ofbenzo[c]phenanthrene (BcP), first we compared it with its parent compound, BcP, using
an in ovo-nanoinjection method in Japanese medaka. Second, we examined the influenceof 3-OHBcP on bone metabolism using goldfish. Third, the detailed mechanism of 3OHBcP on bone metabolism was investigated using zebrafish and goldfish. The LC50s
of BcP and 3-OHBcP in Japanese medaka were 5.7 nM and 0.003 nM, respectively,
indicating that the metabolite was more than 1,900 times as toxic as the parent
compound.

In

addition,

nanoinjected

3-OHBcP (0.001

nM)

inducedskeletalabnormalities. Therefore, fish scales with both osteoblasts and osteoclasts on the
calcified bone matrix were examined to investigate the mechanisms of 3-OHBcP toxicity
on bone metabolism. We found that scale regeneration in the BcP-injected goldfish wassignificantly inhibited as compared with that in control goldfish. Furthermore, 3-OHBcP
was detected in the bile of BcP-injected goldfish, indicating that 3-OHBcP metabolized
from BcP inhibited scale regeneration. Subsequently, the toxicity of BcP and 3-OHBcP
to osteoblasts was examined using an in vitro assay with regenerating scales. The
osteoblastic activity in the 3-OHBcP (10-10 to 10-7 M)-treated scales was significantly
suppressed, while BcP (10-11 to 10-7 M)-treated scales did not affect osteoblastic activity.
Osteoclastic activity was unchanged by either BcP or 3-OHBcP treatment at eachconcentration (10-11 to 10-7 M). The detailed toxicity of 3-OHBcP (10-9 M) in osteoblasts
was then examined using gene expression analysis on a global scale with fish scales.
Eight genes, including APAF1, CHEK2, and FOS, which are associated with apoptosis,
were identified from the upregulated genes. This indicated that 3-OHBcP treatment
induced apoptosis in fish scales. In situ detection of cell death by TUNEL methods was
supported by gene expression analysis. This study is the first to demonstrate that 3OHBcP, a metabolite of BcP, has greater toxicity than the parent compound, BcP (Fig. 3)(Suzuki et al., 2022).
[Toxicity of PAHs on enzyme activities in marine fish]
To examine the influence of BaA on liver diseases, the blood marker enzyme
activities for ALP, AST, LDH, and LAP were measured in the plasma of BaA-treatednibbler fish or untreated nibbler fish. Data are shown in Figure 4.
In the low-dose group, all markers tended to decrease. Significant differences in the ALP
and LDH of the plasma of BaA-treated nibbler fish as compared to that of untreatednibbler fish were observed. At the higher dose, remarkable suppression of ALP was

10obtained. These results indicate that BaA may affect liver diseases and emphasize theimportance of prevention of aquatic PAH pollution (Zanaty et al., 2020).
[Toxicity of PAHs and OHPAHs to sea urchins]
Furthermore, we examined the effect of both PAHs and OHPAHs on the embryogenesisof sea urchins (Hemicentrotus pulcherrimus) (Sekiguchi et al., Fisheries Sci., 2018).
PAHs including BaA are priority pollutants in the aquatic environment. Our previous
study revealed that BaA and its metabolite, 4-monohydroxylated BaA (4-OHBaA) inhibit
larval skeletogenesis in the sea urchin Hemicentrotus pulcherrimus.(Suzuki et al., Comp.
Biochem. Physiol., 2015). Here we report studies to elucidate the target of skeletogenesis
inhibition elicited by BaA and 4-OHBaA. First, we performed an in vitro experimentusing isolated micromeres which give rise to the larval skeletogenic mesenchyme.
However, skeletogenesis was not repressed by BaA and 4-OHBaA, implying that thesechemicals indirectly influence on the formation of larval skeleton. Next, we analyzed
their influence in vivo using embryos. Vascular endothelial growth factor (VEGF) that isexpressed in the ectoderm and induces spicule formation, was inhibited by BaA and 4OHBaA treatment. These chemicals also suppressed the expression of the heparansulfate 6-O endosulfatase known as a VEGF signaling modulator. We therefore proposethat BaA and 4-OHBaA effects on larval skeletogenesis occur via VEGF signaling (Fig.
5).
[Conclusions]
In aquatic animals, we discovered the toxicity of OHPAHs, metabolites of PAHs.
Judging from the obtained data, the toxicity of OHPAHs is stronger than that of PAHs,
at least in fish and sea urchins.
Furthermore, we indicated that PAHs or OHPAHs influences liver metabolism in marine
fish. Thus, OHPAHs that occurred with accumulated PAHs may have toxic influences onaquatic animals, even if the PAH levels in the aquatic environments are low. Thus, weshould emphasize the prevention of aquatic PAH pollution because of the toxicity of
OHPAHs.

compound (in this case, BcP) that is toxic but the hydroxylated congener that is truly

induce the spicule formation. Hp-Sulf is expected to modulate Hp-VEGF signaling.
In addition, Hp-Endo16 is expressed in the digestive tract and repressed by BaA
and 4-OHBaA. Suppression of these genes expressions are expected to result in thephenotype of pluteus larva.

4. Division of Terrestrial Environmental Studies[Outline]
The Sea of Japan area is characterized by the existence of diverse terrestrial
environments. Aiming to understand their temporal and spatial changes and to clearly
define the present, as well as predict future environmental circum- stances, this divisiondevelops geological and geochemical techniques to better understand short-term andlong-term fluctuations. Further, this division uses biological approaches to evaluate theinfluence of human activities on terrestrial ecosystems and employs interdisciplinary
approaches to develop their management strategies.
[Ecology and Conservation]
1) Climate change impacts on the potential distribution of threatened freshwater
crustacean lineages
As climate change presents a major threat to biodiversity in the next decades, it iscritical to assess its impact on species habitat suitability to inform biodiversity
conservation. Species distribution models (SDMs) are a widely used tool to assess climatechange impacts on species’ geographical distributions. As the name of these models
suggests, the species level is the most commonly used taxonomic unit in SDMs. However,recently it has been demonstrated that SDMs considering taxonomic resolution below(or above) the species level can make more reliable predictions of biodiversity change
when different populations exhibit local adaptation. Here, we tested this idea using theJapanese crayfish (Cambaroides japonicus), a threatened species encompassing two
geographically structured and phylogenetically distinct genetic lineages. The specieslevel SDM made future predictions that predicted much broader and severe impacts ofclimate change. However, the lineage-level SDMs led to reduced climate change impacts
overall and also suggested that the eastern lineage may be more resilient to climatechange than the western one.
2) Effects of farming practices on paddy field biodiversity
Agrochemical-free rice farming has attracted interest for restoring paddy fieldbiodiversity and producing safe food. Odonata are commonly used as a biodiversity
indicator in these lowinput farms. However, the effect of agrochemical-free rice farming
on odonate diversity has rarely been assessed over the entire emergence period of these
insects. We investigated whether different farming practices, such as conventional or
natural (agrochemical-and fertilizer-free) cultivation, and associated water management
strategies affect the emergence rates of Odonata in paddy field landscapes in central
Japan (Fig. 1). Weekly exuviae sampling in 2017 and 2019 suggested that odonate
assemblages differed between conventional and natural paddy fields, with a higher

16

number of taxa emerging from natural paddy fields. Contrary to expectations,conventional paddy fields had equivalent or higher emergence rates of all Odonata andtwo numerically dominant Sympetrum species. Our findings suggest that bothconventional and natural paddy fields are important habitats for Odonata in Japan.
3) Developing resource-circulation farming using bamboo biomass resources
Bamboos have expanded their distribution in Japan in recent decades due to theabandonment of forest management practices following depopulation and aging in ruralcommunities. Developing effective uses for bamboo biomass resources is highly desirable.
In this study, we tested the effectiveness of ground bamboo as a new organic mulchingmaterial for agrochemical-free rice farming. Specifically, we tested whether groundculms and leaves with or without refrigeration/fermentation treatments influenced riceproduction differently. We found that straw weights were 1.5–2.1 times greater in thefour ground bamboo treatments relative to controls. As a result, rice yields were 1.8–2.1
times higher in the four ground bamboo treatments relative to controls. Application ofground bamboo did not noticeably reduce rice grain quality. Thus, the use of groundbamboo mulch has considerable potential in increasing the yield of high-quality rice, atleast on a small scale.
[Environmental Pollution and human health risk]
1) In order to investigate the actual situation of environmental pollution in the coastal
area and intertidal zone, especially in the supratidal zone, environmental biomonitoringof the coastal area using wharf roach (Ligia spp.) has been conducted (Fig. 2). The target
area is the coastal area of the Sea of Japan. As a result of analyzing the PAHs between
the wharf roach and surrounding environmental samples in the coastal area andestimating the exposure route of PAHs, it was found that PAHs of three rings or less aremainly from food and soil. It was also suggested that PAHs with four or more rings werepredominantly exposed to seawater and other environmental factors.
2) Biomonitoring of neonicotinoid pesticides and their metabolites in urine is being
conducted to investigate the contamination status of neonicotinoid pesticides in humans
and to evaluate their health effects, around the Sea of Japan. Urinary concentrations ofneonicotinoid pesticides and metabolites were measured in three prefectures during thefarming and off-farming seasons, and relatively high concentrations and frequencies ofpesticides were detected in Niigata Prefecture during the farming season. This result
suggests that pesticide contamination occurs universally through food, especially crops,
regardless of season, but at the same time, it is thought that it also reflects the fact thatthe timing and amount of neonicotinoid pesticide use and the amount of exposure differ
from region to region.

of

Mongolia.

Paleoenvironmental research in Mongolia has two advantages: (a) It locates in the
middle of the continent with a high elevation of ~1500m, sensitive to solar incisionfluctuation. Its climate is governed by three air mass, and depending on which air masses
is dominant, the climate there is highly variable. (b) Human activity is less intense due
to its low population, and the natural geographical environment is more or less preservedin the countryside. There are many lakes and rivers which have been lost recently
because of the increase in the air temperature and decrease in precipitation, especiallyin the arid area. This may be attributable to the global warming caused by humanactivity. We studied changes in lake level and water chemistry by analyzing sedimentcores from lakes, paleo-lake sediments at outcrops, and lake, river, and spring water. We
compared their changes to the climate oscillation to understand how the climate impacts
the environment related to water usage (Fig.3). We also found some of the toxic elements
are captured in sediment, while some stay in the aqueous phase (Fig. 4).
2) Geological maps are the basis of all studies as well as various social services such as
disasterprevention,

environmental

conservation

andlifelongeducation.

Thestratigraphical survey has been carried out in the area of Kanazawa and its environs
since 1994 in order to draw up high-resolution geological maps of the area.
Miocene tuffaceous sandstone in the Komatsu area yields green jasper which was widelyused for ornaments in the Yayoi Era of Japan (Fig. 5). In order to clarify geological andstratigraphical detail of the jasper, lithostratigraphical surveys and petrographicalexaminations of the tuffaceous sandstone have been carried out.
[Social and Cultural Contributions]
The Angkor World Heritage site of Cambodia is one of the most outstanding
cultural heritage in the world. In order to conserve and protect the cultural heritage,natural environment and local society of the heritage (Fig. 6) and its environs, field
examination and inspection have been carried out together with UNESCO and theCambodian government.

The Low Level Radioactivity Laboratory is located in Nomi city, Ishikawa Prefecture.
The division is composed of five research staff members (2017-2019) and four staff
members (2020-2021). The hand-off training of Kanazawa University students andcollaborative research activities with other universities and research institutes arecarried out using radioactive measurement systems. This is aided by the extremely low
background system constructed in the Ogoya Underground Laboratory.
In order to understand the migration behavior of chemical substances in the Earth’s
surface environment, it is necessary to study the transport processes within terrestrial,
atmospheric, and marine environments, as well as their boundary zones. For thispurpose, the division uses environmental tracers such as various stable and radioactive
isotopes, and focuses on polycyclic aromatic hydrocarbons (PAHs), which is toxic
chemical compounds and used as common pollutants of the K-INET. Though the use ofenvironmental tracers and model simulations, the division carries out the integrated
analysis of substances dynamics in the Circum-Sea of Japan area. The understanding
fate of radiocesium released from the Fukushima Daiichi Nuclear Power Plant accident
on 11 March 2011 is important to identify the transport with various processes (sorption,
desorption, concentration, etc.). In final goal, we predict future circumstances by widerange observation and model simulations, using integrated analysis of pollutants
dynamics in terrestrial-atmospheric- marine environments.
[Ogoya Underground Laboratory]
Ogoya Underground Laboratory (OUL) is constructed in the Ogoya-Kuratani tunnelof the former Ogoya Copper Mine in Komatsu City. Measurement room is located in the
middle of the tunnel where the overburden is 135m (270 m water equivalent) to reducethe background noise derived from secondary cosmic-ray components (muons andneutrons). Ge semiconductor detectors are shielded with the low background materials(210Pb-free Pb and 60Co-free Fe blocks) to achieve ultra-low background noise at about
1/100 of the aboveground value (Fig. 1). The 15 Ge detectors are installed in OUL andused for ultra-low level radioactivity measurements. The annual number of users was
771 (2017 FY), 615 (2018 FY), 685 (2019 FY), 576 (2020 FY), and 736 (2021 FY),
respectively. During 2017-2019, in OUL, we particularly measured concentrations ofradiocesium in seawater samples for assessments of Fukushima Dai-ichi Nuclear Power
Plant accident, and other low-level radionuclides in environmental samples asgeochemical tracers, including a joint usage/research collaborative researches (MEXT).
[Transport of 134Cs in northern North Pacific Ocean]20

Cesium-134, all of which are the 2011 Fukushima Dai-ichi Nuclear Power Plant(FDNPP) accident-derived considering its short half-life (2.06 y), is a useful tracer forseawater circulations after the supply from off northeastern Japan. The detection of
134Cs

in the Bering Sea in 2018 was ascribed to the arrival of FDNPP-derived

radiocesium-rich Alaskan Stream water (Inoue et al., 2020). Subsequently, off thesoutheastern Hokkaido, Japan (Doto area), the distribution of 134Cs concentrations in
2018–2019 indicated that134Cs

was partially transported along with the East

Kamchatka Current (EKC) from the northeastern North Pacific Ocean (Inoue et al.,2021). The 134Cs concentrations at the surface in Doto area gradual increased from 2018
to 2020, and subsequently decreased to 2022 (Fig. 2a). It is considered that highly-134Cs
affected water masses had returned to Japan Islands side as the Oyashio Current (OYC)
after the mixing with other currents andvia EKC in the maximum effect in 2020

convection. Transport image of FDNPP-derived 134Cs in the northern North Pacific
Ocean is shown in Fig. 2b. Further study regarding 134Cs circulation systems in thewestern North Pacific Ocean could be realized by the continual measurements of 134Cs
concentrations. This study is currently on-going by our research team.
[Dynamics of radionuclides released from the Fukushima Daiichi Nuclear Power Plant
accident in freshwater environment]
A large amounts of radionuclides was released from the Fukushima Daiichi Nuclear
Power Plant by the nuclear accident on March 11, 2011. Our laboratory has been
investigating the dynamics of radiocesium in land (soil, rivers, and lakes) and coastal topelagic marine environments. During 2017-2021, we performed the monitoring researchat a fixed site in the upper Tone River, the lower Natsui River, the Abukuma Riversystem, and rivers at Hamadori area in Fukushima Prefecture. The activity of 137Cs
exponentially decreased with increasing time after the accident, though the pulse input
was observed at the rain events. Figure 3 shows temporal changes in the normalized
dissolved 137Cs concentration, Cw(t)/D = Ae-(λ+k)/t, which Cw = 137Cs concentration attime t, D: initial inventory of 137Cs at t = 0, A: the weight of exponential component, λ+k: effective decreasing coefficient, t: time (Ochiai et al., 2021). The regression lines wasdetermined using data two years after the accident. The transport of dissolved 137Cs fromthe watershed has decreased the 10 years since the accident. The slope of the regression
lines is almost similar with the river systems except for the upper Tone River. Possible
consideration is related to differences in watershed conditions at the lower reaches andthe upper reach (Tone River). The summarized knowledge and dataset of geochemicaland biological behavior of radiocesium, and tritium from the accident in freshwater
systems were published as an academic book (Nagao, S. (ed.) Impacts of Fukushima21

[Study on the transport processes of earth surface materials and atmosphericradionuclides in Nanao Bay]
To understand the transport processes of earth surface and atmospheric materials
from terrestrial environment to downstream coastal area, studies on (1) transport
processes of suspended sediment in Kumaki River in Noto Peninsula, (2) sedimentation
processes in West Nanao Bay located in the downstream of Kumaki River were
performed by using atmospheric radionuclides (7Be ， 210Pb, 137Cs). Additionally, (3)transport processes of these atmospheric radionuclides in the small reservoir and its
catchment area.
Figure 4 shows 137Cs and 210Pb distribution, grain size, and magnetic susceptibilityof bottom sediments in West Nanao Bay (Ochiai et al., 2022). Surface sedimentconcentrations and inventories of these radionuclides were relatively low in the middle
and eastern areas of the bay and high in the western area, which has several major rivermouths, suggesting that the contribution of riverine input affected only the western area.
In the middle and eastern areas, the level of 137Cs inventory was much lower than thatof the soils, and the excess 210Pb inventory was at the same level or lower. These results
indicate that removal effects are stronger than accumulation effects (riverine input) inthese areas. The patterns of radionuclides were consistent with the results, that grain
size was relatively large in the middle and eastern areas, implying strong current
conditions, and that fine sediment accumulated less in these areas.
[Spatial and temporal variations in marine polycyclic aromatic hydrocarbons at thecoastal Sea of Japan]
Polycyclic aromatic hydrocarbons (PAHs), originating mainly from the incomplete
combustion of fossil fuels and biomass and the leakage of petroleum products, arehazardous pollutants with adverse carcinogenic and mutagenic potential. Investigationof the environmental behavior of PAHs in the East Asian marginal seas is essential inassessing the ecological risk of anthropogenic PAHs, since these seas are one of the mostfertile fishing ground. Concentrations of 13 phase-partitioned PAHs in seawater weremonitored monthly off Okinawa Island, Oki Island, Noto Peninsula (Tsukumo Bay), Sado
Island, Japan, during 2015–2021 to elucidate seasonal variations, main source, andtransport pathways of PAHs in the southwestern Sea of Japan (Fig. 5A). Total
concentrations of the 13 dissolved PAHs (Σ13PAHdiss) component, contributing 95% of theΣ13PAH (= Σ13PAHdiss + Σ13PAHpart) concentration, was in the range 0.43–9.32 ng L−1

22

(mean 2.62, SD 2.08 ng L−1), with higher values in summer–autumn during 2015–2019(Fig. 5B). The main sources of dissolved PAHs were combustion products (Fig. 5C).
Increasing dissolved PAH levels during July–October indicate that the area aroundsouthern Oki Island is impacted by PAH-rich summer continental-shelf watertransported by the Tsushima Warm Current flowing from the East China Sea(Matsunaka et al., 2022).
[Surface and vertical distributions of polycyclic aromatic hydrocarbons in seawater at
the East Asian marginal seas and Arctic Ocean]This study clarified the surface distribution of PAHs in seawater at the East Asian
marginal seas, North Pacific Ocean, and Arctic Ocean in 2019. Σ13PAHdiss at each oceanarea in 2019 are illustrated in Fig. 6 A. Σ13PAHdiss in surface seawater were in the range
1.61–6.11 ng L−1, with the relatively higher mean values were observed at the South
China Sea, Sea of Japan, Okhotsk Sea, and Bering Sea and lower values at the East
China Sea, western subarctic North Pacific, and Arctic Ocean. The Σ13PAHdiss inseawater collected from surface to 1000 m water depth at the South China Sea were in
the range 1.96–4.12 ng L−1, with the maximum values being recorded at water depth of
200 m, as found the PAH maximum layer (water depth of 100–150 m) at the East China
Sea, Sea of Japan, and Okhotsk Sea in 2017 and 2019 (Fig. 6 B).

6. Department of Inter-Institutional Collaboration
The Japan Sea Research Institute of Kanazawa University established in 1963
became the Department of Regional Studies at the Institute of Nature andEnvironmental Technology in 2007. Over again, the department was reorganised into
the Department of Inter-Institutional Collaboration as a part of a reorganisation
programme of the institute in 2016.
The Department of Inter-Institutional Collaboration manages the collection,exchange, and maintenance of environmental information in the area of entire East Asia
while centred on the Circum-Sea of Japan, and it constructs and sustains international
research networks in the area to disseminate information all over the world (Figs. 1 and
2). The department promotes interdisciplinary research in the area that is ageopoliticallyimportantregionintheworld.

Italso

supports

students’internationalisation education.
The Circum-Sea of Japan region in which industrialised countries are located canbe recognised as a core of East Asia in various settings, environmental issues inparticular. The department has been trying to expand its interdisciplinary activities tothe whole East Asian region and to coordinate them. As a part of the activities, thedepartment publishes a scientific journal named “Japan Sea Research (“Bulletin of theJapan Sea Research Institute, Kanazawa University” before 2017)” which contains
original articles, short articles and so forth on in various research fields such as natural,
human, and social sciences related only in the region (Fig. 3).
Further, the department has been organising a series of international thematic
symposia "Rural and Urban Environment in the countries of the Modern Circum-Sea ofJapan" since 2017, in order to understand the dynamics of the rural and urban societies
in the circum-Sea of Japan countries (Fig. 4), because it is necessary to understand first
the rural and urban environment which is the basement of Chinese society from theviewpoint of historical and environmental background in comparison with the society ofJapan. The topics of the serious situation of China’s air, water and soil pollution, which
are negative aspects of industrial development have been also discussed.
The department supports students’ internationalisation education at Kanazawa
University. Since 2010, the department has been coordinating a students’ international
internship programme which sent ten undergraduate students belonging to various
schools and colleges of the university to the APSARA National Authority of Cambodia
which manages the conservation and maintenance of the Angkor World Heritage site as
one of the most famous world heritage sites of UNESCO. The students have been
engaged in the routines of the authority to learn environmental management such as

29

monitoring of groundwater levels, water quality surveys in local rivers and afforestationin the areas of the site (Fig. 5).
