This study aimed to monitor abiotic factors at three stations in the Oum Er Rbia estuary, not far from the mouth. The stations were situated upstream (S1), in front (S2) and downstream (S3) from the discharge of urban wastewater from the town of Azemmour, which is discharged directly without treatment near the estuary mouth. The selection of these stations appeared appropriate to assessing the quality of the waters, which are influenced by both marine hydrodynamics resulting from very low freshwater inflows and sewage discharges. Monitoring of several parameters, including temperature, pH, dissolved oxygen, conductivity, salinity, turbidity, as well as the content of chlorophyll a and pheopigments, enabled the examination of the impact of marine hydrodynamics and the and the specific characteristics of the three surveyed stations. The analyses were performed using R software version 4.2.0. The results obtained indicate that the studied physico-chemical and biological parameters exhibited variations with significant correlations. Statistical approaches allowed the determination of profiles for stations S1, S2 and S3. It is evident that S1 (located slightly far from the discharge) showed a profile that tended to differ from the other two stations, S2 and S3, especially for certain parameters (temperature, pH, turbidity, and chlorophyll a ). On the other hand, all stations were impacted to some extent by the discharge of wastewater during rising tides. The present study can serve as an assessment tool to support decision-making regarding the physico-chemical quality of the waters of the Oum Er Rbia estuary.
本研究旨在监测乌姆厄尔比亚河口不远处三个站点的非生物因素。这些监测站分别位于阿泽姆穆尔镇城市污水排放口的上游（S1）、前方（S2）和下游（S3）。由于淡水流入量极少，加上污水排放，水质受到海洋水动力的影响，因此选择这些站点来评估水质似乎是合适的。通过对温度、pH 值、溶解氧、电导率、盐度、浊度以及叶绿素 a 和嗜褐藻色素含量等参数的监测，可以研究海洋水动力的影响以及三个调查站的具体特征。分析使用 4.2.0 版 R 软件进行。结果表明，所研究的物理化学和生物参数呈现出显著相关的变化。通过统计方法确定了 S1、S2 和 S3 站的概况。很明显，S1 站（离排放口稍远）与其他两个站（S2 和 S3）显示出不同的轮廓，特别是某些参数（温度、pH 值、浑浊度和叶绿素 a）。另一方面，所有站点都在一定程度上受到涨潮时废水排放的影响。本研究可作为一种评估工具，支持有关乌姆河河口水域物理化学质量的决策。

The research was conducted on the Bila Tserkva National Agrarian University experimental field on a typical deep, low-humus chernozem. The methods of main cultivation in the sunflower agrocenosis of grain-row crop rotation had a major influence on the soil structuring processes. The use of moldboard and no-moldboard tillage increased the number of the most agronomically beneficial aggregates (0.25–10 mm) in the 0–10 cm soil’s layer at the begin - ning of the sunflower growing season by 6.0% compared to shallow no-moldboardof tillage the soil. By the end of the growing season in the sunflower agrocenosis in the 0–30 cm soil layer, compared to the beginning of the crop growing season, the number of agronomically beneficial aggregates (0.25–10 mm) decreased, the number of frac - tions larger than 10 mm and fractions smaller than 0.25 mm increased. The coefficient of structure for moldboard and no-moldboard tillage significantly increased compared to shallow no-moldboardof tillage. The use of shallow no-moldboardof tillage and moldboard with no-moldboardof tillage was led to an increase in the content of stable aggregates by 1.2–7.5%. The highest yield of sunflower was recorded for the use of moldboard with no-mold - boardof tillage – 2.72 t/ha, which is significantly higher than other variants. The use of shallow no-moldboardof tillage for 10–12 cm with disc tools led to a notable decrease in productivity compared to the control. Improving the water resistance of soil aggregates during moldboard and no-moldboard tillage and shallow no-moldboardof tillage helps to preserve the soil’s potential fertility.

Seaweed species have a positive effect on the bioremediation of nutrient waste. However, waste absorption ef - ficiency varies between species. This research aims to analyze the most efficient seaweed as bioremediation of intensive waste ponds. The method used in this research was three types of seaweed stocked based on treatment groups in each of three tanks measuring 100×100×100 cm made of bamboo, wood, and specially designed tar-paulin. This study was carried out on a laboratory scale for 42 days on three local seaweed species to evaluate the waste disposal efficiency of each seaweed species. This research was conducted at the Bone Marine and Fisheries Polytechnic Laboratory, Tulang Daerah, South Sulawesi Province, Indonesia, from September to October 2022. Measurement of ammonia (NH 3 -N), nitrite (NO 2 -N), nitrate (NO 3 -N), and phosphate (PO 4 -P) carried out at the Center for Brackish Water Aquaculture and Fisheries Extension in Maros, the concentrations of the four nutrient wastes were significantly different (P<0.05), indicating differences in nutrient removal for each seaweed species. The removal efficiency of NH 3 -N, NO 2 -N, NO 3 -N, and PO -P by G. verrucosa (97.1, 99.7, 99.9, 99.7%) was significantly higher (P<0.05) compared with E. spinosum (90.5, 93.9, 96.4, 95.4%) and K. alvarezii (81.6%, 94.6%, 94.5%, and 95.4%, respectively). Meanwhile, E. spinosum was not significantly different (P>0.05) from K. alvare-zii in removing NO 2 -N, NO 3 -N, and PO 4 -P but was more efficient in reducing NH 3 -N. Overall, G. verrucosa is the most efficient in intensive disposal of shrimp pond waste based on the results of this study.
海藻物种对营养废物的生物修复有积极作用。然而，不同种类的海藻对废物的吸收能力各不相同。本研究旨在分析最有效的海藻对密集型废物池塘的生物修复作用。本研究采用的方法是在三个面积分别为 100×100×100 厘米的池塘中按处理组投放三种类型的海藻，池塘分别由竹子、木头和专门设计的防水油布制成。这项研究在实验室对三种本地海藻进行了为期 42 天的试验，以评估每种海藻的废物处理效率。这项研究于 2022 年 9 月至 10 月在印度尼西亚南苏拉威西省 Tulang Daerah 的 Bone 海洋与渔业理工实验室进行。在马罗斯咸水养殖和渔业推广中心进行的氨氮（NH 3 -N）、亚硝酸盐（NO 2 -N）、硝酸盐（NO 3 -N）和磷酸盐（PO 4 -P）测量结果显示，在去除 NO 2 -N、NO 3 -N 和 PO 4 -P 方面，四种营养废物的浓度与 K. alvare-zii 有显著差异（P0.05），但在减少 NH 3 -N 方面效率更高。总体而言，根据本研究的结果，疣尾藻类在集中处理虾池废物方面效率最高。

Activated carbon (AC) is one of the best adsorbents for removing trace contaminants from air, soil and water due to its adsorption properties. It is produced from carbon-rich materials, mainly fossil raw materials. However, the price of hard coals has increased significantly in recent years due to the COVID-19 pandemic and the war in Ukraine. The existing eastern markets became blocked for carbon-raw-material sourcing. It is therefore important to find alternative materials or plant-based products. This study investigated the possibility of manufacturing activated carbon from waste biomass such as sugar beet fibers (SBSF), mixed vegetable processing waste (mainly corn) (MVW) and cherry stones (ChS). The raw material was subjected to pyrolysis, milling, granulation, carbonisation and activation at different times and temperatures. However, of the biomass materials tested, only SBSF in the form of marc can be processed into valuable activated carbon in further production steps. MVW and ChS as carbon substrates showed, in addition to high moisture and ash, low efficiency in decolourising molasses and methylene blue MB and also had a lower specific surface area.

The problem of recovering water from treated wastewater may concern an increasing number of countries, especially those with low water resources. After costly treatment processes, water taken from surface and underground intakes is used and then largely discharged to receivers in the form of treated wastewater. Advanced wastewater treatment methods ensure that the treated wastewater is characterized by very low physical and chemical pollution, sometimes better than the water quality in the receiving basin. The research was conducted under a cooperation agreement between Bialystok University of Technology and Bialystok Waterworks Ltd. The recovery of water from wastewater was one of the topics pursued.This paper analyzes the parameters of treated wastewater from the largest municipal wastewater treatment plant in the Podlaskie Province. The analysis of the treated wastewater composition was based on monitoring studies conducted by the company Bialystok Waterworks Ltd. between 2020 and 2023. The analysis concerned the basic parameters of wastewater, namely the content of organic matter and total suspended solids.This was due to the requirements for the recyclability of treated wastewater. Linear modeling was performed to determine if a sufficiently strong correlation was detected;otherwise output distribu - tion characteristics were provided.In all cases, the output concentrations were far below the class A limits for irrigation in the whole research period.
越来越多的国家，尤其是水资源匮乏的国家，都在关注从处理过的废水中回收水的问 题。从地表和地下取水口取来的水经过昂贵的处理工艺后被使用，然后大部分以经过处理的废水的形式排放到接收器中。先进的废水处理方法可确保处理后的废水物理和化学污染极低，有时甚至优于受水流域的水质。这项研究是根据比亚韦斯托克理工大学和比亚韦斯托克水务有限公司之间的合作协议进行的。本文分析了波德拉谢省最大的城市污水处理厂处理过的废水参数。对处理后废水成分的分析基于比亚韦斯托克水务有限公司在 2020 年至 2023 年期间进行的监测研究。分析涉及废水的基本参数，即有机物和总悬浮固体的含量。通过线性建模来确定是否检测到足够强的相关性，否则将提供输出分布特征。在所有情况下，输出浓度在整个研究期间都远远低于灌溉的 A 级限值。

One of the greatest threats to many lakes is their accelerated eutrophication resulting from anthropogenic pressure, agricultural intensification, and climate change. A very important element of surface water protection in environmentally conserved areas is the proper monitoring of water quality and detection of potential threats by examining the physicochemical properties of water and performing statistical analyses that enable possible exposure of unfavourable trends. The article presents the analyses of the results of measurements made in three lakes located in the Sierakowski Landscape Park. As part of the measurements, water quality indicators i.e., phosphorus, nitrogen, BOD 5 and COD, were determined monthly for a year at the inflows and outflows of the studied lakes. The test results of selected water quality indicators were analysed using machine learning algorithms i.e., PCA and k -means. The conducted tests enabled statistical estimation of changes in water quality indicators in the reservoirs and evaluation of their correlation.
许多湖泊面临的最大威胁之一是人为压力、农业集约化和气候变化导致的湖泊富营养化加速。在环境保护区保护地表水的一个非常重要的因素是通过检查水的物理化学特性和进行统计分析来适当监测水质和发现潜在威胁，从而揭示不利趋势。文章介绍了对位于 Sierakowski 景观公园的三个湖泊的测量结果进行的分析。作为测量工作的一部分，在所研究湖泊的流入口和流出口每月测定水质指标，即磷、氮、生化需氧量 5 和化学需氧量，为期一年。选定水质指标的测试结果使用机器学习算法（即 PCA 和 k -means）进行分析。通过测试，可以对水库水质指标的变化进行统计估算，并对其相关性进行评估。

This study assessed the effectiveness of integrating electrocoagulation, magnetic fields, and ozonation technolo - gies to remove chemical oxygen demand (COD) and total suspended solids (TSS) from tannery wastewater. Fur - thermore, the effects of their key operating factors were determined. To achieve this goal, an electrocoagulation re - actor coupled with a magnetic-field generator was used and the response surface methodology was applied through a Box-Behnken experimental design. Here, current intensity (I), treatment time (T), and ozone concentration (O 3 ) are considered the influencing factors. Likewise, the removal percentages of COD and TSS serve as response indicators. The results indicate that T, I, and O 3 are significant for the removal of COD and TSS at a confidence level of p-value < 0.05. For COD, the optimal operating conditions are I = 6.8 A, T = 30 min, and O 3 = 10 mg/l; and for TSS, the optimal conditions are I = 5.72 A, T = 28 min, and O 3 = 7.8 mg/l. These conditions yield removal efficiencies of 41.8% for COD and 97.9% for TSS. The findings suggest that integrating these technologies is a viable alternative for mitigating the pollution issues caused by the tannery industry.
