Long-term unsystematic use of near-settlement pastures in the desert zone of South Kazakhstan had a negative impact on the physic-chemical parameters of Calcisol . Excessive grazing leads to trampling of soil and reduction of soil fertility. The aim of the study was to develop a technology to improve the productivity of degraded near-settlement pastures. The tasks of the research were to determine the effect application of environmental safe biostimulator and biofertilizer on microbial communities, the content of carbon and phosphorus in the soil, the effectiveness of biostimulator application on degraded pastures in order to increase green mass. For this purpose, geobotanical, bacteriological and helminthological methods of analysis were used. The result of the used proposed technology is the activation of soil microorganisms, which leads to the prevention of degradation of arid pastures. The results of the conducted research contribute to the introduction of a better technology to increase the productivity of arid near-settlement pastures. Statistical analysis of the experiments showed that all manipulations on soil microorganisms increase the number and green mass of arid plants.

The controlling microplastics (MPs) at source is a management method that can effectively reduce the amount of contamination in the environment. The main source of MPs was landfills that the decomposition of solid waste, MPs has an impact on environmental quality especially the health of humans. This research was investigated of MPs contamination at landfill site in the Muangpak municipality for analysis of MPs quantitative and source ap - portionment of MPs. The results of the composition of municipal solid waste by quartering method found that bio-degradable solid waste was as high as 36.27% followed by general solid waste of 35.97% which was mostly plastic waste and effect the contamination of MPs in the environment. The distribution of MPs in environmental found that highest abundance was 66.44% of leachate sludge pond 1 followed by leachate sludge pond 2 (26.30%), sediment of surface water (3.32%), leachate pond 1 (1.04%), leachate pond 2 (0.80%), groundwater point 3 (0.62%), groundwater point 1 (0.58%), surface water (0.53%) and groundwater point 2 (0.37%). The contamination of polymer types of MPs at higher densities of low density polyethylene (LDPE) and high density polyethylene (HDPE) than polypropylene (PP) was found in samples closest to landfill area especially leachate pond more than 90%. The source apportionment of MPs using statistical analysis found that plastic waste has correlated to occurrence of LDPE and plastic bottle waste has correlated to occurrence of HDPE that both types of plastic waste are related to the amount of general solid waste and recycle solid waste increases every year.

Abandonment of the use of agricultural areas, especially low-production grass communities, and the related secondary succession of trees and shrubs, affects the transformation of the soil environment. The work focused on the impact of extensive sheep grazing on activity of dehydrogenases (DhA) and neutral phosphatase (PhA) and the resources of total organic carbon (TOC) and available phosphorus (Pav) in the soils of meadow habitats in eastern Poland. These habitats are located within the ecological network Natura 2000: PLH060018 Stawska Góra, PLH060035 Zachodniowołyńska Dolina Bugu, PLH060010 Kąty and the Nature Reserve “Kózki” (PLB140001 Dolina Dolnego Bugu and PLH140011 Ostoja Nadbużańska). Soil material was collected for three years, twice each year: before and after the grazing. In the soils of all the studied habitats, a beneficial effect of extensive sheep grazing on soil en - zymatic activity and TOC and Pav content was noticed. A particular marked improvement was observed in the biochemical status of the soil in the study area where sheep grazing was continued since 2008. This confirms the hypothesis that free grazing of livestock has a positive impact on biodiversity and the condition of the soil environment of Natura 2000 habitats.
放弃使用农业区，特别是低产草地群落，以及相关的树木和灌木次生演替，会影响土壤环境的变化。这项工作的重点是大面积放牧绵羊对脱氢酶（DhA）和中性磷酸酶（PhA）活性的影响，以及对波兰东部草地栖息地土壤中总有机碳（TOC）和可用磷（Pav）资源的影响。这些栖息地位于 Natura 2000 生态网络内：PLH060018 Stawska Góra、PLH060035 Zachodniowołyńska Dolina Bugu、PLH060010 Kąty和 "Kózki "自然保护区（PLB140001 Dolina Dolnego Bugu和PLH140011 Ostoja Nadbużańska）。土壤材料收集了三年，每年两次：放牧前和放牧后。在所有研究栖息地的土壤中，大量放牧羊群对土壤酶活性、总有机碳（TOC）和总磷（Pav）含量都产生了有益的影响。在自 2008 年以来持续放牧绵羊的研究区域，土壤的生化状况得到了明显改善。这证实了自由放牧对生物多样性和自然 2000（Natura 2000）栖息地土壤环境状况有积极影响的假设。

The quality of indoor air in educational institutions is a critical determinant of the health and well-being of students. The purpose of the study was indoor air quality monitoring carried out for different age groups of students in grades IV–VIII or college classrooms (students used the classroom according to the schedule, the same group uses the room for up to 2 classes), I–III (students stay in the classroom for all classes, leaving only during breaks), kin - dergarten “0” (students are practically in one and the same room all day). The individual measurements included measurement of CO 2 concentration, concentration of PM2.5 and PM10 particles, formaldehyde, volatile organic compounds (VOCs), along with monitoring of changes in temperature and humidity in the classroom. The results indicate that children are exposed to elevated levels of these pollutants for a significant portion of their school day, which can have implications for their health and well-being. The findings reveal significant deviations from the recommended levels, emphasizing the need for improved ventilation and monitoring practices.

The present study aimed to assess the impact of leachates from the emerging cell on the water quality of the Limón stream in Ecuador. Five sampling points were selected as references using the NTE INEN 2176:2013 standard. Subsequently, these samples were analyzed in a laboratory using the standard methods for the examination of water and wastewater for the respective physicochemical analysis. The analysis results were compared with the Unified Text of Secondary Legislation of the Ministry of the Environment, and the water quality index (WQI) was determined according to the National Sanitary Foundation (NSF). Additionally, an environmental diagnosis was conducted based on the cause-effect matrix by Leopold to propose a strategy for the restoration and ecological recovery of the affected components. According to the obtained results, the sampling points closer to the leachate discharge showed high concentrations of dissolved oxygen, iron, fecal coliforms, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS), which exceeded the maximum per-missible limits according to legislation. This resulted in a “fair” water quality index classification according to the WQI classification. These findings highlight the importance of considering and assessing the environmental impacts. A total of 24 impacts were identified on physical, biotic, and anthropic components, with 4.76% being highly significant, 42.86% significant, and 52.38% negligible. In conclusion, the results indicate a scenario of envi - ronmental deterioration at the leachate discharge stations, urging the urgent implementation of corrective measures to address the detected high contamination.

As a part of the marine ecosystem, seagrass plays a significant role in the coastal environment. However, due to increased threats from natural causes and anthropogenic pressures, seagrass decline will likely begin in many areas of the world. Therefore, several studies have been carried out to observe seagrass distribution to help resolve the issue. Remote sensing is often used due to its ability to achieve high accuracy when distinguishing seagrass dis - tribution. Still, this method lacks in species classification because not all satellites and similar aerial vehicles have fine spatial resolution to distinguish distinct species of seagrass. In this study, we aim to address the issue by utiliz - ing unmanned aerial vehicles (UAV), which are known for providing finer resolution and better imagery. Samuh Beach at Tanjung Benoa, Bali, Indonesia, was chosen as the study site location because it experiences high levels of marine tourism and anthropogenic activities. From the UAV flight mission, the images obtained were processed. The result’s accuracy was also tested with an error matrix. The species found in this study are Enhalus acoroides , Halodule pinifolia , Thalassia hemprichii , Cymodocea rotundata , and Syringodium isoetifolium , with 65% overall accuracy of the species classification map. This result indicates that UAVs can be a strong option for similar studies in the future. In addition to that, this study was able to observe the scars on the seagrass beds left by boat propeller activities from marine tourism. However, further research is needed to gain a better understanding of these objects.

Grasses are often used to recultivate areas contaminated during shale gas extraction. This is due to the fact that they adapt very well to unfavorable soil conditions such as: high pH, salinity, water deficit or the presence of harmful substances. Additionally, the grass root system releases enzymes into the soil that increase the activity of micro - organisms and bacteria that decompose polycyclic aromatic hydrocarbons (PAH), which are the main component of drilling waste. In turn, assessment of initial growth and development (germination tests) is a cheap and quick method to assess the sensitivity of the tested plants to pollutants. Young plants are more susceptible to harmful substances. The study aimed to determine the effect of drilling waste, containing polycyclic aromatic hydrocarbons (PAHs) on the initial growth and development of selected grass species, with a specific focus on germination en - ergy and capacity, as young plants are more sensitive to harmful substances compared to older plants. Among the tested species, Lolium perenne and Festuca rubra showed the highest energy and germination ability, while Poa pratensis showed the lowest. The experiment showed that of the tested grass species, Lolium perenne and Festuca rubra were the least sensitive to the effects of PAHs, with the smallest reductions in root length and seedling height observed in these species. Additionally, the highest concentration of PAHs was found in soil seeded with Lolium perenne , while the lowest was found in soil seeded with Poa pratensis .

Employers of the companies where carcinogenic chemicals are being processed or used are obliged to ensure safe working conditions for their employees. Butan-2-one oxime, commonly present in alkyd paints or silicone sealants may pose such a risk due to its reclassification as a category 1B carcinogen. Therefore, in Poland new maximum admissible concentrations (MAC) value of 1 mg/m 3 was proposed by interdepartmental Commission for maximum admissible concentrations and intensities for agents harmful to health in the working environment. Assessing exposure to this compound requires a method to be developed for its determination in the workers’ breathing zone, which was the aim of the presented study. A method was developed for determining the aerosol concentrations of 2-butanone oxime in the air at workplaces, in the range of 1/10 to 2 of the MAC value, i.e. from 0.1 mg/m 3 to 2 mg/m 3 . The method involves trapping the airborne aerosol of 2-butanone oxime onto a sampler - a glass tube with silica gel, its extraction with methanol and analysis of the resulting solution using gas chromatography with flame ionization detector in the presence of co-substances. Validation parameters were determined according to the guidelines of EN 482. The limit of detection at 6.79 ng/ml and the relative total uncertainty of 11.19% was determined. The method can be used by environmental occupational hygiene laboratories to measure concentrations of butan-2-one oxime in the air.

Butan-2-one oxime, commonly present in alkyd paints or silicone sealants may pose such a risk due to its reclassification as a category 1B carcinogen. Therefore, in Poland new maximum admissible concentrations (MAC) value of 1 mg/m 3 was proposed by interdepartmental Commission for maximum admissible concentrations and intensities for agents harmful to health in the working environment.
