The overuse of antibiotics in healthcare and animal husbandry has led tothe spread of antibiotic resistance genes (ARGs) in the aquatic
environment, posing a significant threat to public health. Understanding
ARG behavior during drinking water treatment is crucial for developing
control strategies. Regarding advanced drinking water treatment byactivated carbon (AC), biological AC adsorbers increase ARG abundance
due to biofilm formation. In addition, powdered AC may promotehorizontal gene transfer (HGT) during the recycling process of water fromdrinking water treatment sludge (DWTS) as raw water. Pore size
distribution (PSD) of AC is one of the most important property
parameters affecting the adsorption process. Different molecules havedifferent sizes, and their ability to be adsorbed depends on whether they
can access into the pores of AC. In this study, the uptake of ARGs into thepores of AC was investigated, and the influence of the PSD of AC on theuptake capacity was evaluated through adsorption experiments withdifferent types of ACs. Plasmid-encoded genes and fragmented genes
were used as a model of ARGs. In addition, the effect of coexisting
dissolved organic matter (DOM) on the uptake of ARGs was also
examined since DOM can be a potential competitor to ARGs for the active
sites of AC. Results showed that the uptake kinetic of ARGs followed apseudo-second-order kinetics reaction, and the uptake rate constantvaried depending on the type of AC. Moreover, analysis of the uptake
capacity of ARGs based on the Freundlich isotherm model determinedthat the adsorption strength (KF) for plasmid-encoded genes andfragmented genes were 1.28×10-2 ‒ 9.00×108 (copies mg-1)1-1/n and1.71×103 ‒ 3.00×1010 (copies mg-1)1-1/n, respectively. Correlation
analysis of the relation of the uptake capacity with pore volume and poresurface area in different pore size regions of all ACs showed that thelargest correlation coefficient was found with the pores of 50‒240 Å forplasmid-encoded gene and 20‒30 Å for fragmented gene. For theadsorbability of DOM, the KF values of fluorescence excitation-emission
matrix (EEM)-based fulvic acid-like and humic acid-like substances werehigher than those of tyrosine-like and tryptophan-like substances. This
study has been published in various scientific journals such as
Chemosphere (Vol. 339, 2023, 139679) and Journal of Water Resources
and Protection (Vol. 16, 2024, 1-16). The findings of this study can be used
as an important reference for optimizing the adsorption process(including AC selection) to mitigate the risks from ARGs in water. For risk
management of drinking water production, the selection of ACs should
be made by considering the positive effect of AC in admitting the genes
into their pores and also any likely negative effect if admitted genes
could release from the pores to the water and hence cause horizontaltransfer. For the latter effect, a systematic study is also necessary, which
will be conducted.

My doctoral thesis research is related to the transfer and eliminationof antibiotic resistance genes in decentralized wastewater
treatment process treating household wastewater. The main objectiveof this study wastoinvestigate
theperformanceof
decentralized
householdwastewater
treatment
facilities(DHWWTFs) in controlling general pollutants, bacteria and ARGs
fromhouseholdwastewater,
hence optimizing
on-sitemaintenance and operation of the DHWWTF to eliminate thetransfer of ARGs and further improving the treatment performance.
For this, this study was carried out mainly by three systematicinvestigations: For the first part, clarification the transfer,elimination, and accumulation of ARGs while they were
undergoing decentralized household wastewater treatment processes.
The fate and behavior of tetG, tetM, sul1, sul2 and intl1 werequantitively studied through real-time PCR-based quantification,
mass balance evaluation and the existing state analysis based on size
fractionation. Second part is determination of factors affecting thegeneral treatment performance of small-scale DHWWTFs. Wastewater
samples were collected from 15 FBCRs treating individual
household wastewater, each with varying waste sludge cleaningtime. These samples were subjected to measurements ofsuspended substances (SS), biological oxygen demand (BOD), chemicaloxygen demand (COD), total organic carbon (TOC), total nitrogen (TN),and total phosphorus (TP). The measurement results, along withthosefromprincipal
components
analysis(PCA)
andagglomerative hierarchical clustering (AHC), led to the classificationof the facilities into three groups (G1, G2, and G3) based on theirdifferent treatment performances. The third part relates to insights into
enhanced control of transfer of genes in individual DHWWTFs
based on the investigation of differences in bacteria and ARGs among
DHWWTFs with varied treatment performances. The findings of thisstudy have been published in Science of the Total Environment (Vol.
912, 2024, 169144, Cite Score: 16.8) and Journal of Water Process
Engineering (Vol. 56, 2023, 104340, Cite Score: 9.7), and could beused as references for better controlling the performance ofdecentralized household wastewater treatment facilities not onlyin eliminating the transfer of bacteria and ARGs, but also inoptimizing the operation and maintenance of treatment facilities andfurther improving the treatment performance: 1) Elimination ofbacteria and ARGs especially ARGs in smaller particles andfreeARGs
canbeachieved
throughthe enhancement
for settleability of slow-settling and transferable small particles; and2) Optimization treatment performance of facilities could be achievedby improving the properties of biofilm and sludge.

Voice from New Student / 新入生の声
Time flies like an arrow in a blink of an eye. My master's degree was conducted under the BWEL program. It
seems like just yesterday that I wrote my introduction as a new student in the master's course, but 3 years havepassed. During my time here, I not only gained a lot of knowledge and experience, but more importantly, I also
learned a lot of different but wonderful cultures, and have made many friends and seniors with similar interests. Allof these make me look at things from a broader and deeper perspective.
However, I realized that my knowledge base and communication skills are still insufficient to support my dream ofbecoming a lecturer, so I decided to continue my study as doctoral course student with the support of theBWEL program. From April, I am going to start the second year of my PhD study. My research topic is about
Wenqing Li (China) evaluation and control of membrane fouling by microorganisms in surface water for drinking water production.
New ideas and inspirations generated during discussions and communication with my supervisor and program
Affiliation /Graduate School of Engineering members are helping me a lot to promote my PhD research. After graduation, I would like to be a lecturer or engage inenvironmental-related work. I will do my best to become an excellent environmental leader like seniors.

Overseas Field Study / 海外現場研修
学生の国際性と流域水環境への理解深化を促進するために，8月8日から8月14日の7日間，海外現場研修を中国の山西省呂梁市，北京市，天津市で実施しました．プログラム学生4名に加え，プログラムの開講科目を履修した日本人学生3名も参加し，水環境，およびエネルギー関連施設などを訪問し中国における環境への取り組みや現状について研修を行いました．呂梁市では，呂梁市環境局，柳林県環境文化局の担当者から柳林の環境・社会・経済状況の説明を受けるとともに，自然と人文歴史景観と有機的に融合した柳林県を流れる清河と，柳林県から40キロ離れている三交鎮黄河古渡口（昔渡しの船の発着場）をそれぞれ見学し，中国の中で発展が比較的遅れている地域の現状と水環境，黄河文化などを理解する良い機会となりました．北京市においては，古い住居区における給排水・衛生環境の現状と，都市発展の最前線にある大興区におけるグリーン排水システム，省エネと環境保全の取り組みの見学調査を行いました．また，北京市の地理的環境の特徴に順応し，600年前に作られ今でもしっかり機能している紫禁城内の排水システムも見学し，中国の古代文化と歴史のみでなく，先人の知恵や創意工夫についても肌で感じることができました．天津市では，都市河川である海河と海河沿いで形成された古い街と街の給排水を調査し，同時に海河の地域経済の発展への貢献ならびに天津の経済成長が水環境への影響，その対策方法等について理解を深めました．
To promote students' internationality and deepen their understanding of watershed environmental issues, a seven-day overseas field study was
conducted from August 8 to 14 in Lvliang City in Shanxi Province, Beijing, and Tianjin, China. In addition to four students from the program, threeJapanese students who had taken courses offered by the program also participated. In Lvliang City, after receiving explanations on theenvironmental, social, and economic conditions of Liulin from officials of the Lvliang City Environmental Bureau and the Liulin County Environmental
Culture Bureau, students visited the Qing River, which flows through Liulin County and is organically integrated with natural and cultural-historicallandscapes, and the Yellow River old port in Sanjiao town, 40 kilometers from Liulin County. This visit provided a good opportunity to understandthe current situation of relatively underdeveloped areas in China, water environment issues, and Yellow River culture. In Beijing, students conducteda survey on the current status of water supply and sanitation in old residential areas and visited Daxing District's green drainage system,
energy-saving, and environmental conservation efforts at the forefront of urban development. They also visited the 600-year-old drainage system within
the Forbidden City, which is still functioning well, providing a firsthand experience of China's ancient culture and history, as well as thewisdom and creativity of the predecessors. In Tianjin, students investigated Haihe River, an urban river, and the old town formed along theHaihe, as well as the town's water supply and drainage. They also deepened their understanding of the Haihe's contribution to regional economic
development, and the impact of Tianjin's economic growth on the water environment, and strategies to address these issues.
