Crop yield variations in the Orinoquía region – Colombia, are primarily associated with extreme precipitation events. Therefore, studying crop water supplies under naturally variable climate conditions is fundamental in an actual climatic change context. Rainfall data collected in the Quenane sub-basin were analyzed to understand the soil water dynamics in the Orinoco catchment. The basin covers 179 km 2 and consists of the piedmont landscape (Eastern Mountain Range) of the Villavicencio Municipality, Department of Meta. This study analyzes the rainfall variability using Pearson correlation analysis, the Mann-Kendall trend analysis, and soil water balance to determine the implications of these factors in crop performance at the basin scale. The results indicated that the spatial distribution of rainfall in the basin responds to a longitudinal average variation of precipitation and that this response is more accentuated (i.e., greater rainfall) toward the west of the basin. Despite the basin being located in the tropical zone, no evidence was found regarding the effect of the El Niño Southern Oscillation on rainfall patterns. Yet, the temporal analysis revealed some years with extreme rainfall values and high-uncertainty levels during transitions between wet and dry periods. During these transition periods, a greater potential for effects on farm yields exists due to the variable cumulative rainfall observed during recent years. The time series trend analysis revealed changes in rainfall patterns at different scales (weekly and yearly) and distribution based on the decrease of rainy days per week and year. This trend is much more accentuated during the second half of the year, generating uncertainty and reducing farm yields throughout the basin.

This study performs a life cycle assessment (LCA) on the wastewater treatment operations at Sebelas Maret University in Surakarta, Indonesia, with the goal of systematically evaluating the environmental impacts associated with its processes. LCA serves as a comprehensive method for assessing environmental impacts across all stages of a product’s life cycle, which includes goal and scope definition, life cycle inventory (LCI), life cycle impact as - sessment (LCIA), and interpretation. Utilizing this methodology, our analysis categorizes environmental impacts into three significant domains: human health, ecosystem quality, and resource depletion. The findings indicate that human health is the most impacted category, showing an effect of 0.275 disability-adjusted life years (DALY) -equivalent units. Resource depletion follows, measured at 0.193 DALY-equivalent units, and non-renewable en - ergy consumption is quantified at 0.0214 DALY-equivalent units. To address these impacts, the study proposes several improvement strategies, such as adopting more sustainable clean water treatment technologies, capturing and utilizing methane gas through anaerobic digestion, and establishing green spaces for CO 2 sequestration. These strategies aim to reduce the environmental footprint of the wastewater treatment process, moving towards more sustainable management practices.
本研究对印度尼西亚泗水 Sebelas Maret 大学的废水处理业务进行了生命周期评估（LCA），目的是系统地评估与处理过程相关的环境影响。生命周期评估是评估产品生命周期各阶段环境影响的综合方法，包括目标和范围定义、生命周期清单（LCI）、生命周期影响评估（LCIA）和解释。利用这种方法，我们的分析将环境影响分为三个重要领域：人类健康、生态系统质量和资源损耗。研究结果表明，人类健康是受影响最严重的类别，其影响达到 0.275 个残疾调整寿命年（DALY）当量单位。紧随其后的是资源损耗，为 0.193 个残疾调整生命年当量单位，而不可再生能源消耗的量化影响为 0.0214 个残疾调整生命年当量单位。针对这些影响，研究提出了若干改进策略，如采用更可持续的清洁水处理技术、通过厌氧消化收集和利用甲烷气体，以及建立二氧化碳封存绿地。这些策略旨在减少废水处理过程的环境足迹，向更可持续的管理方法迈进。

Biomass, primarily derived from photosynthesizing plants harnessing solar energy, is crucial for ecosystem func - tioning and diverse services. This study delved into the unique ecosystem of coal mine heaps, exploring unex - pected relations between abiotic factors and biomass in spontaneous vegetation. Biomass quantity and quality are influenced by such factors as plant photosynthesis efficiency, necessitating an understanding of dynamics on post-mining sites. The conducted investigation focused on diverse spontaneous vegetation on coal mine heaps, analyz - ing abiotic conditions such as soil texture, water holding capacity, pH, electrical conductivity, nitrogen, carbon, magnesium, sodium, and acidity. Contrary to the adopted hypothesis, nitrogen content negatively correlates with soil total nitrogen, carbon, and water holding capacity. However, the biomass of dominant plant species positively correlates with available phosphorus, pH, calcium, and sodium. These unexpected relationships highlight biomass dynamics complexity in novel ecosystems on coal mine heaps, stressing the need to consider spontaneous vegeta - tion biomass as a valuable resource and ecosystem service in urban-industry landscapes. The obtained findings ex - pand scientific inquiry and have practical implications for post-industrial area reclamation. Understanding biomass potential in identified vegetation types provides insights into biomass character on coal mine heaps, crucial for maximizing spontaneous vegetation potential and transforming post-industrial landscape reclamation approaches.

Finding a thermal insulation material that is naturally available, cheap, and effective for minimising energy losses is a challenge for geotechnical engineers in Jordan. Previous research suggests the use of mineral wool, polyurethane, or air layers as an insulation material but so far, the basalt has not been used as an insulation material in Jordan. The objective of this study was to measure and compare the thermal conductivity ( K ), bulk density (ρ B ), porosity (ɛ) and chemical composition of the basalt from Hashemiah area and Hulial mountain in Jordan in order to evaluate the rock as a thermal insulation material. A total of fourteen samples, seven for each zone, were evaluated. The thermal conductivity was measured using transient plane source technique (TPS) at ambient temperature. Porosity and density were measured by the standards of the American Society of Testing Materials (ASTM). The chemical composition of the samples was analysed by X-Ray diffraction to include the effect of aluminium oxide on thermal conductiv - ity analysis. Experimental values covered the range of ɛ between 0.008–8.7%; ρ B between 2.54–2.93 g/cm 3 and K between 1.62–2.98 W/mK. The experimental K values were compared with allometric fit and theoretical prediction models. In general, thermal conductivity tends to decrease with porosity in basalt samples. This study found increasing conductivity values with ɛ when ferromagnesian-aluminium oxide concentration reached levels above 38% and porosity less than 4% indicating that high percentages of these oxides decrease the insulating effect of the air in the empty spaces of the basalt at reduced porosity levels. Low values of conductivity and percentage of ferromagnesian-aluminium oxides characterise the Jordanian basalt in the Hashemiah area and makes it better for insulation than the Hulial mountain basalt. The experimental values presented in this work are important for predicting the optimum insulation thickness and predicting energy losses in construction buildings where basaltic rocks are used.
对于约旦的岩土工程师来说，寻找一种天然、廉价、有效的隔热材料来减少能源损失是一项挑战。以往的研究建议使用矿棉、聚氨酯或空气层作为隔热材料，但迄今为止，约旦尚未使用玄武岩作为隔热材料。本研究的目的是测量和比较约旦哈希米亚地区和胡利亚尔山的玄武岩的导热系数（K）、体积密度（ρ B）、孔隙率（ɛ）和化学成分，以评估玄武岩作为隔热材料的性能。共评估了 14 个样本，每个区域 7 个。热导率是在环境温度下使用瞬态平面源技术（TPS）测量的。孔隙率和密度按照美国材料试验协会（ASTM）的标准进行测量。通过 X 射线衍射分析了样品的化学成分，包括氧化铝对热导率分析的影响。实验值的范围包括：ɛ 在 0.008-8.7% 之间；ρ B 在 2.54-2.93 g/cm 3 之间；K 在 1.62-2.98 W/mK 之间。实验得出的 K 值与异速拟合模型和理论预测模型进行了比较。一般来说，玄武岩样本的导热率会随着孔隙率的增加而降低。本研究发现，当铁镁铝氧化物浓度达到 38% 以上、孔隙率小于 4% 时，电导率值会随着ɛ 的增加而增加，这表明这些氧化物的高比例会降低玄武岩空隙中空气在孔隙率降低时的隔热效果。哈希米亚地区的约旦玄武岩的导电率和铁镁铝氧化物百分比值较低，这使其比胡利亚尔山的玄武岩具有更好的隔热性能。这项工作中提出的实验值对于预测使用玄武岩的建筑中的最佳隔热厚度和预测能量损失非常重要。

The article addresses the problem of the presence of selected pharmaceuticals in waters by determining the state of scientific knowledge. The sources of drug residues in the aquatic environment were characterized and the most important information was collected on the toxicity measures of the most commonly used drugs, including NLPZ: (1) non-steroidal analgesics and antipyretics (diclofenac, ibuprofen, phenazone, acetaminophen, propy - phenazone, indomethacin, ketoprofen, pentoxifylline, and phenacetin), (2) pharmaceuticals used to reduce blood lipid levels (bezafibrate, fenofibrate, gemfibrozil), (3) drugs used in cardiac conditions, in particular those used to lower blood pressure and treat arrhythmia (atenolol, sotalol, metoprolol), (4) antibiotics (trimethoprim, clar-ithromycin, amoxicillin, sulfamethoxazole, piperacillin, erythromycin, sulfadimidine, dehydrate-erythromycin, 4N-Acetylsulfamethoxazol), (5 )drugs used to treat rheumatoid arthritis (naproxen, fenoprofen), and (6) anticon - vulsants, drugs used in neuropathic disorders and tranquilisers (carbamazepine, diazepam, primidone, oxazepam, temazepam). The authors reviewed research papers dealing with the indicated issue, taking into account: (1) research on the presence of pharmaceuticals in water, (2) studies on the health and environmental risk of drinking water for the presence of drug residues and their mixtures, (3) research on the effectiveness of water treatment in terms of pharmaceuticals. Gaps in scientific knowledge have been demonstrated, which are a hint for the direc - tions of future research work.

The Paris Agreement came into force in 2016. Now, there are 196 parties to this Agreement, including Russia. The purpose of the accommodation is to hold the increase in the global average temperature below 2 °C and to make ef - forts to limit the temperature increase to 1.5 °C. Another important goal of this Agreement is to reduce greenhouse gas emissions, according to UNFCCC-2015. Each participating country at the national level plans special activities that will help to achieve these goals. In general, this should reduce the rate of global warming. The goals of the Paris Agreement can be achieved either by introduction of new technologies that exclude the formation of a large amount of carbon footprint or termination of the usage of fossil fuels for electricity production. The formation of a carbon footprint is observed at all mining enterprises, regardless of the extracted raw materials. In this case, the amount of carbon footprint depends only on the extraction technologies and the success of ecological measures.

Sorghum stem ( Sorghum bicolor L . ) is a plant that has not been maximally utilized. But sorghum stems contain high cellulose. The hydroxyl (OH-) and carboxyl (-COOH) groups on cellulose can bind heavy metals; therefore, sorghum stems have the opportunity to be used as an adsorbent to absorb heavy metals, especially Cu(II) metal, which can pollute the environment. Therefore, this research was conducted to determine the optimum pH, contact time, and the adsorption capacity of Cu(II) using HNO 3 modified sorghum stem adsorbent. The stages of the re - search included the preparation of sorghum stem adsorbent, modification of adsorbent with HNO 3 , determination of optimum pH, optimum contact time and adsorption capacity of Cu(II) metal. Furthermore, the functional groups of the adsorbent before and after modification were determined by FTIR. SEM-EDS to assess the morphological structure and chemical components contained in the adsorbent. After the research, the optimum pH of Cu(II) metal adsorption was pH 6, and the adsorption power was 99.88%. The optimum contact time is 10 minutes. The percent removal of Cu(II) metal with concentrations of 10, 30, 50, and 100 ppm were 79.96; 79.90; 56.40 and 54.04%, respectively. Adsorption of Cu(II) metal using HNO 3 modified sorghum stem adsorbent followed the Freundlich isotherm pattern compared to Langmuir with R 2 = 0.9039. It is concluded that activated sorghum stem can be used as Cu(II) metal adsorbent.

Introducing vegetation into towns and cities, for example through establishing green corridors which ensure a continuous character of urban green areas is a way to counteract negative effects of urban climate. The aim of the study was to assess the role of a green corridor and the contribution of vegetation to regulating the level of hourly tropospheric ozone concentrations in Legnica. Hourly values of tropospheric ozone concentrations (O 3 , μg m -3 ) and wind directions (D, °) collected between 2011 and 2014 from an urban background station for air quality monitoring of the Provincial Inspectorate for Environmental Protection were used in the study. To prepare a land cover map, data from the Database of Topographic Objects provided by the Geodesy and Cartography Department of the Marshal’s Office of the Lower Silesian Voivodship were used. The estimations of frequency of hourly O 3 concentrations for given seasons of the year and the analysis of land cover within 2 km from the measuring point were made based on an 8-wind compass rose. In summer, the frequency of hourly O 3 concentrations was assessed for every direction and for every hour of the day. A Pearson correlation matrix was generated to illustrate the rela - tionship between land cover type and the frequency of pollution coming from each direction, Between 21:00 and 6:00, increased frequency of hourly O 3 concentrations in the 0–40 μg m -3 range coming from the southwest was recorded, which accounted for 70–90% of all concentration ranges. Correlation analyses showed a statistically significant relationship between increased high vegetation coverage and decreased frequency of hourly O 3 concentrations in the 41–80 μg m -3 range. It was demonstrated that between 2011 and 2014, during summers, hourly O 3 concentrations <40 μg m -3 came most frequently from the direction characterised by the highest total share of vegetation-covered land. On the other hand, pollutants with concentrations in the 41–80 μg m -3 range came more frequently at night time from the directions characterised by compact and dense development. The obtained results demonstrated that in summer, the urban park, the Kaczawa River and the green areas along the river play an im - portant role as a green ventilation corridor.
在城镇引入植被，例如建立绿色走廊，确保城市绿地的连续性，是抵消城市气候负面影响的一种方法。这项研究旨在评估绿色走廊的作用以及植被对调节莱格尼察每小时对流层臭氧浓度水平的贡献。研究采用了 2011 年至 2014 年期间从省环境保护监察局空气质量监测城市背景站收集的对流层臭氧浓度小时值（O 3，μg m -3）和风向（D，°）。为绘制土地覆盖图，使用了下西里西亚省元帅办公室大地测量和制图部提供的地形物体数据库中的数据。根据八级风罗盘升高图估算了一年中特定季节每小时 O 3 浓度的频率，并分析了测量点 2 公里范围内的土地覆盖情况。在夏季，对每个方向和每天每个小时的每小时臭氧浓度频率进行了评估。在 21:00 至 6:00 期间，记录到来自西南方向的 0-40 μg m -3 范围内的每小时 O 3 浓度频率增加，占所有浓度范围的 70-90%。相关分析表明，高植被覆盖率的增加与 41-80 μg m -3 范围内每小时 O 3 浓度频率的降低之间存在显著的统计学关系。结果表明，在 2011 年至 2014 年期间的夏季，每小时 O 3 浓度小于 40 μg m -3 的情况最常见于植被覆盖率最高的方向。另一方面，浓度在 41-80 μg m -3 范围内的污染物在夜间更多地从密集发展的方向出现。研究结果表明，在夏季，城市公园、卡泽河和沿河绿地作为绿色通风走廊发挥着重要作用。
