Published: July 2018

Processes regulating population connectivity are complex, ranging from extrinsic environmental factors to intrinsic individual based features, and are a major force shaping the persistence of fish species and population responses to harvesting and environmental change. Here we developed an integrated assessment of demographic and genetic connectivity of European flounder Platichthys flesus in the northeast Atlantic (from the Norwegian to the Portuguese coast) and Baltic Sea. Specifically, we used a Bayesian infinite mixture model to infer the most likely number of natal sources of individuals based on otolith near core chemical composition. Simultaneously, we characterised genetic connectivity via microsatellite DNA markers, and evaluated how the combined use of natural tags informed individual movement and long-term population exchange rates. Individual markers provided different insights on movement, with otolith chemistry delineating Norwegian and Baltic Sea sources, whilst genetic markers showed a latitudinal pattern which distinguished southern peripheral populations along the Iberian coast. Overall, the integrated use of natural tags resulted in outcomes that were not readily anticipated by individual movement or gene flow markers alone. Our ecological and evolutionary approach provided a synergistic view on connectivity, which will be paramount to align biological and management units and safeguard species’ biocomplexity.

The current study aimed at genomic characterization and improved understanding of genetic diversity of two Indian mithun populations (both farm, 48 animals and field, 24 animals) using genome wide genotype data generated with Illumina BovineHD BeadChip. Eight additional populations of taurine cattle (Holstein and NDama), indicine cattle (Gir) and other evolutionarily closely related species (Bali cattle, Yak, Bison, Gaur and wild buffalo) were also included in this analysis (N = 137) for comparative purposes. Our results show that the genetic background of mithun populations was uniform with few possible signs of indicine admixture. In general, observed and expected heterozygosities were quite similar in these two populations. We also observed increased frequencies of small-sized runs of homozygosity (ROH) in the farm population compared to field mithuns. On the other hand, longer ROH were more frequent in field mithuns, which suggests recent founder effects and subsequent genetic drift due to close breeding in farmer herds. This represents the first study providing genetic evidence about the population structure and genomic diversity of Indian mithun. The information generated will be utilized for devising suitable breeding and conservation programme for mithun, an endangered bovine species in India.

Published: July 2018

OceanRAIN—the Ocean Rainfall And Ice-phase precipitation measurement Network—provides in-situ along-track shipboard data of precipitation, evaporation and the resulting freshwater flux at 1-min resolution over the global oceans from June 2010 to April 2017. More than 6.83 million minutes with 75 parameters from 8 ships cover all routinely measured atmospheric and oceanographic state variables along with those required to derive the turbulent heat fluxes. The precipitation parameter is based on measurements of the optical disdrometer ODM470 specifically designed for all-weather shipboard operations. The rain, snow and mixed-phase precipitation occurrence, intensity and accumulation are derived from particle size distributions. Additionally, microphysical parameters and radar-related parameters are provided. Addressing the need for high-quality in-situ precipitation data over the global oceans, OceanRAIN-1.0 is the first comprehensive along-track in-situ water cycle surface reference dataset for satellite product validation and retrieval calibration of the GPM (Global Precipitation Measurement) era, to improve the representation of precipitation and air-sea interactions in re-analyses and models, and to improve understanding of water cycle processes over the global oceans.

Influence of passive house technology on time and cost of construction investment
Authors: Apollo Magdalena , Miszewska-Urbańska Emilia
Published: July 2018

Due to the changes in the energy standards for housing in Poland there are many concerns. Is the standard required by the regulation achievable and if it is, then at what cost?

There are many solutions to construct a building in line with the requirements of passive house technology. They are differentiated by price and time required for implementation. This study is based on the solution proposed by one of Polish companies, offering technologically integrated products allowing, according to the producer, to build passive houses faster and easier. The goal of this study was to confront producer’s claim with reality by comparing time and cost of the same investment using conventional and passive house technology. The basis for time and cost analysis was a basic detached house design, partially modified with regards to materials and technology used.

Conclusions of the study are based on the comparison of the two Gantt charts defined in Ms Project. Construction schedule was used to analyse the duration of both projects and the resources assignment was used in cost analysis.

Published: July 2018

Numerical experiment with the use of software products, such as Ansis, Star–CD, Star-CCM+ and other, helps get the fields of distributing parameters in different environments. In case of conducting numerical simulation one of the main tasks is to select the most appropriate turbulence model. This work presents analysis of results of numerical simulation of ventilation processes in production premises with spatial heat sources located on the platforms above floor level with the use of Spalart-Allmaras (SA) and k-ε turbulence models as well as LES method. A comparison of results of full-scale experiment and numerical simulation has been performed. A turbulence model k-ε has been used in numerical investigations of heat-and mass exchange processes in the nozzle of cellular humidifier of system of processing plenum air. The analysis of results of calculation and experimental data acquired at experimental installation is shown. The condition of microclimate in the working zone of premises significantly depends on the peculiarities of heat exchange through external building structures. This work presents results of numerical simulation of heat exchange through cold floors on the ground and in case of presence of underlining in the production premises with sources of heat emissions with the use of k-ε turbulence model.

Authors: Bezyk Yaroslav , Dorodnikov Maxim , Grzelka Agnieszka , Nych Alicja
Published: July 2018

Understanding the origin and mechanisms controlling GHGs (CO2, CH4 and N2O) emission spatially and temporally is critical for evaluating future climate changes. Whether the controls on GHG dynamics in urban ecosystem are similar to those in natural ecosystems are not fully understood. In the current study, the aboveground (cover vegetation + soil) and soil (including autotrophic and heterotrophic) CO2, N2O and CH4 fluxes and respective carbon stable isotopic composition (δ13C) of respired CO2 at natural abundance level were simultaneously measured from a re-established grassland in the urban area of central Germany. The static chamber system (combination of transparent and opaque modes) was applied to assess the effects of intensive vegetation growth during two weeks of April 2017. The values of CO2 fluxes obtained with both transparent and opaque chambers differed significantly due to the combined effects of the incoming photosynthetically active radiation (PAR) and temperature on vegetation and belowground processes. The average value of measured CO2 flux with opaque chambers was 9.14 ± 1.9 (mg m-2 min-1) vs. 2.37 ± 0.9 (mg m-2 min-1) with transparent chambers for the re-established grassland. In contrast, soil CH4, as well as N2O fluxes were not different significantly for both opaque-transparent chamber measurements. Current magnitude provides the pattern of the urban ecosystem source/ sinks potential during ambient light conditions.

Authors: Czajczyńska Dina , Ahmad Darem , KrzyŻyńska Renata , Jouhara Hussam , Rutkowski Piotr
Published: July 2018

Food waste generation is one of the most crucial problems of our constantly developing world. There are several common methods of its treatment, however each one has its own advantages and disadvantages. Pyrolysis attracting attention in this field since a long time, because it allows to utilize this valuable resource with energy and material recovery. Moreover, the environmental impact of the process is relatively low. In this paper, products of low temperature household waste pyrolysis underwent a detailed chemical analysis. Liquid and solid residues was examined. Composition and concentration of particular compounds and elements indicates presence of long chain alkane, alkene and carboxylic acid molecules together with small amounts of aromatics within the bio-oil samples. The presence of heavy metals in residues was detected, too. Since the products are usually described as non-toxic, the idea of waste’ low-temperature thermal treating in household was analyzed. In general, examined residues from the process are safe for the environment, thus pyrolysis can be considered as a legitimate mechanism to treat kitchen waste combined with energy recovery for homes.

Published: July 2018

In the terms of forest soil protection function and the limitations of these functions resulting from forest works, the authors aim was to determine the intensity and spatial range of erosion, and the volume of soil material loss resulting by erosion processes and human activities. The remote sensing technique – terrestrial laser scanning (TLS) was used in the research of erosion processes occurring in the mountain forest on the surface of the skid trails. The measurements were performed with laser scanning resolution of 3×4 mm. Obtained points clouds have been interpolated to the digital terrain models 1 cm, which allowed evaluating the erosion phenomena using the method of differential models in the period of 2011–2013. In the study it was analysed the part of the skid trail (ca. 41 m2, ca. 35% average slope). It was determined that during the entire research period the amount of soil material loss was ca. 1.9 m3. The erosion processes occurred mainly in the form of sheet erosion with volume ca. 1.3 m3. The erosion processes in the form of sheet erosion occurred ca. 49% and 42% of trail section area, respectively. Results of the study indicate that it is efficient to use TLS for the monitoring of the erosion phenomena, qualitative and spatial range assessment. At the same time, it has been proven that intensive water erosion processes can also occur in forests.

Environmental-economic analysis of the heating system for a single-family building
Authors: Jachura Agnieszka
Published: July 2018

This paper discusses the use of modern and effective heating systems, using fossil fuels and renewable energy sources on the example of a comparative analysis of a gas boiler and heat pump for a single-family building. The aim of the work was to conduct a comparative analysis of heating systems in terms of energy, economy and ecology. The concepts of heating systems based on a gas boiler and a heat pump are proposed. An economic analysis based on the LCC and ecological method was carried out, related to the equivalent emission, in order to compare the degree of environmental nuisance of the proposed heat sources. For the building in question, a more advantageous solution was the use of a system based on a condensing gas boiler. The economic analysis shows that in the assumed life cycle (20 years), the total cost for a heating system based on a gas boiler is lower than in the case of a heat pump by 11%. Also, the initial costs in this variant are lower by nearly half compared to the heat pump system. Environmental analyzes have shown lower annual emissions of pollutants and a 6-fold lower equivalent emission for a gas-fired heating system.
Potential of existing and newly designed geothermal heating plants in limiting of low emissions in Poland
Authors: Kaczmarczyk Michał
Published: July 2018

Geothermal energy as one of renewable energy sources is an alternative to conventional methods of heat production, and thus contributes to reducing the emission of pollutants into the environment, especially the so-called low emission. Poland is facing the problem of pollutant emissions from combustion processes, in the context to individual households using mainly solid fuels to ensure heat demand for central heating and hot water production. The paper presents the results of calculations of avoided emissions in the context of replacement of conventional individual heating for geothermal heating systems, taking into consideration not only the problem of air pollution in Poland, but also issues of fuel quality (calorific value) and efficiency of used heating devices.

In this paper a new validation test for the spatial weather generator SWGEN producing the multisite daily time series of solar radiation, temperature and precipitation is presented. The method was tested by comparing statistics of 1000 years of generated data with extra long series of 35 years of observed weather parameters and 24 sites of meteorological stations for south-west Poland. The method evaluation showed that the means (sums) and variances of generated data were comparable with observed climatic data aggregated for months, seasons and years.
Toxicological analysis of water mixtures of organic micropollutants subjected to UV irradiation
Authors: Kudlek Edyta
Published: July 2018

The paper presents the toxicological analysis of water solutions of micropollutants from different groups i.e. industrial additives, pharmaceutical compounds, hormones, UV blockers and pesticides before and after their exposure to UV light. The toxicological response of both Microtox® and Daphtoxkit F® test, increased with the increase of the compound concentration. Triclosan water solution was considered as the most toxic. The lowest toxic effect was observed for Imidacloprid and Octyl-methoxycinnamate solutions. The exposure of Benzocaine, Octyl-methoxycinnamate and Triclosan water solutions to UV light led to an increase of their toxicity. An inverse relationship was observed for Imidacloprid and 17α-Ethinylestradiol solutions.
Ammonia and conventional engine fuels: comparative environmental impact assessment
Authors: Lasocki Jakub
Published: July 2018

Ammonia has recently attracted great attention as a fuel for internal combustion engines. The aim of this study was to compare the environmental impact caused by the production processes of ammonia and conventional engine fuels – gasoline and diesel oil. Present fuel technology, commonly used in Europe, was investigated. Haber-Bosch process for ammonia synthesis was considered, coupled with steam methane reforming (SMR) and partial oxidation of heavy oils (POX) as sources of hydrogen. Fuel technology was evaluated with the use of Life Cycle Assessment (LCA), based on a total emission of selected pollutants, including greenhouse gases, total consumption of water and primary energy, as well as Eco-indicator 99 score. LCA results indicated that current industrial methods for ammonia production have unambiguously more negative impact on the environment, compared to fossil fuel technologies, when energy content of the fuel is taken into account. The environmental load of ammonia production process depends strictly on the method of hydrogen obtaining. SMR has lower negative impact on the environment than POX. In order for ammonia to be considered as a potential transportation fuel, the use of hydrogen generation pathways that are less burdensome to the environment should be promoted.

Fourier-transform infrared spectroscopy (FT-IR) enables the passive detection and identification of chemical agent clouds from distances. It can be used for the monitoring of large spaces and protection of industrial installations outside buildings. The aim of the study was show the possibilities and limitations of passive FT-IR. In studies done by the Faculty of Fire Safety Engineering at the Main School of Fire Service were used spectrometer RAPID (Remote Air Pollution Infrared Detector), Bruker Daltonics Company. Hazardous substances such as acetone, methanol, ammonia was identified on-line from several observation points at 25 m, 50 m and 75 m. The tests were carried out at various meteorological conditions. The results indicate that remote infrared detection allows detecting hazardous chemical agents in the atmosphere from a distance. Nevertheless, meteorological and terrain conditions have a big impact on the measurement results. During measurements, the detector indicated the presence of other substances. Moreover, it was found that under cloudy and windy weather, remote detection is not possible.

Published: July 2018

This paper regards the possibility of using geopolymer matrix to immobilize heavy metals present in ash and slag from combustion of medical waste. In the related research one used the fly ash from coal combustion in one Polish CHP plant and the waste from two Polish incineration plants. It was studied if the above-named waste materials are useful in the process of alkali-activation. Therefore, two sets of geopolymer mixtures were prepared containing 60 and 50% of ash and slag from the combustion of medical waste. The remaining content was fly ash from coal combustion. The alkali-activation was conducted by means of 14M solution of NaOH and sodium water glass. The samples, whose dimensions were in accordance with the EN 206-1 norm, were subjected to 75°C for 24 h. According to the results, the geopolymer matrix is able to immobilize heavy metals and retain compressive strength resembling that of C8/10 type concrete.

Authors: Milik Julita , Pasela Rafał , Budzińska Katarzyna
Published: July 2018

The aim of the study is to assess the quality of water from selected recreational fountains in Ciechocinek and Inowrocław health resorts. All analyzed water fountains are characterized by seasonal changes in their discharge. The exceedance of biochemical oxygen demand and chemical oxygen demand values found in the water samples may indicate water contamination with compounds of organic origin getting from the external environment to the basin of the fountain or too little recirculation of water. A significant improvement in water quality was noted in fountains in which water exchange occurred due to, for example, its failure. In addition, the water was characterized by a relatively high content of general hardness and conductivity. Reported exceedances of water quality parameters disqualify it for direct human consumption. It does not meet the requirements for drinking water. It is recommended to introduce supervision over the quality of water from fountains by the bodies of the State Sanitary Inspection in the form of water monitoring in order to eliminate from the water compounds that may have a negative impact on human health. It is recommended to regularly use pre-filtration, chlorination and sodium hypochlorite in water in fountains to eliminate physical impurities.

Published: July 2018

Aeration is considered as one of the most energy consuming process during the wastewater treatment process and its proper design plays important role in further overall wastewater treatment plant energy balance. Design guidelines for aeration systems in mainstream treatment of municipal wastewater are well known, however there are some doubts about transferring them to sidestream treatment installations. Different process rates, reactors geometry and treated medium composition may significantly affect aeration efficiency and this case must be verified. Series of alpha factor measurements were performed during start-up of shortcut nitrification process of real reject water from sludge dewatering. Surprisingly, observed alpha factor values were close and higher than 1.0 which is uncommon for such aeration devices as used in this study. Paper presents discussion of potential reasons of observed facts and outlines directions of further work.

Published: July 2018

Chemicals addition at the mechanical part of wastewater treatment plant can improve overall treatment efficiency and help in solving some plant’s operational problems. Application of such process in the primary clarifiers, named as Chemically Assisted Primary Sedimentation, can also be a huge step towards energy balance improvement for the whole plant. Use of relatively cheap coagulants, such as ferric or alum salts can be an easy way to increase treatment efficiency significantly, as coagulation and flocculation intensifies followed by chemical precipitation. Additional removal of soluble pollutants and suspended solids increases their load in the primary sludge, avoiding their potential removal in the biological part of the plant. Additional organic matter in the primary sludge allows to produce more gas in the anaerobic digestion process and thus increase energy production by the CHP units. Efficiency of different coagulation agents (PIX 109 and PAX XL3) supported by polymer addition was investigated using real municipal wastewater collected from a large Polish wastewater treatment plant (over 500 000 p.e.) in a series of lab-scale tests. Proper selection of coagulant and potential polymer dosage has a serious impact on the overall costs of this additional treatment and energy balance. Based on obtained results, economic analysis was performed for the same plant to evaluate potential gains and losses of implementing such practice.

Published: July 2018

For proper enumeration of protozoa in activated sludge good methodology is required. In this paper we present some remarks on microscopic methodology of protozoa enumeration. This remarks concern number of repetitions from one sample required to obtain good statistical results as well as influence of sample aeration on number of found protozoa. Presented data shows that at last 10 repetitions are required from each sample to obtain low average confidence interval. Lower number of repetitions leads to sharp increase in average confidence interval and loss of statistical significance while higher number does not decrease average confidence interval substantially. As measurements lasts for few hours lack of sample’s aeration during measurement leads to detection of lower by 27% number of protozoa.
