A disastrous sudden blackening of the river Kameng in Arunachal Pradesh, known as the river Jiya Bharali in Assam, was studied to find its cause and effects. The water of the river suddenly turned turbid and black on October 29, 2021, causing a large-scale death of fish for several days creating panic among the surrounding people. Samples of water and sediment were collected from different locations of the river and were analysed. The results indicate an increase in TSS consisting of aluminosilicates and oxides of Fe, Mn, Co, Ni, etc., mixed with water due to landslides. Coloured metal oxides were found to cause the blackening while toxicity and suffocation due to excess of suspended microscopic particles may have led to the death of fish. Preventive and curative measures for the disaster have been suggested.
对阿鲁纳恰尔邦卡蒙河(在阿萨姆邦被称为吉亚巴拉利河)突然变黑的灾难性事件进行了研究,以找出其原因和影响。2021 年 10 月 29 日,河水突然变得浑浊发黑,导致鱼类大量死亡,并持续数日,引起了周围居民的恐慌。我们从河流的不同位置采集了水和沉积物样本,并对其进行了分析。结果表明,由于山体滑坡,由铝硅酸盐和铁、锰、钴、镍等氧化物组成的总悬浮物与水混合后有所增加。结果发现,有色金属氧化物是导致水体变黑的原因,而悬浮微粒过多可能导致鱼类中毒和窒息死亡。针对这一灾害提出了预防和治疗措施。

Smart water meters play a significant part in the interactive control of water supply networks required for smart cities. Opposed to completely mechanical water meters, electro-mechanical water meters or fully electronic water meters can capture real-time data via an automated meter reading process, making them more appropriate for smart city applications. However, the depletion of fresh water supplies as a result of climate change, as well as the rising demand associated with population increase, are some growing concern in many regions globally. Monitoring water distribution and delivery is a critical strategy for increasing distribution efficiency. This paper presents a wireless transceiver unit that can be integrated with existing electronic water meters. The unit utilises a reliable communication algorithm for real-time data exchange. Metering data is transmitted using cutting-edge narrow-band Internet of Things technology that operates using low power whilst covering a wide range with effective penetration.
智能水表在智能城市所需的供水网络互动控制中发挥着重要作用。与完全机械式水表相比,机电式水表或全电子式水表可以通过自动抄表过程获取实时数据,因此更适合智能城市的应用。然而,气候变化导致的淡水供应枯竭,以及与人口增长相关的需求上升,是全球许多地区日益关注的问题。监测配水和输水是提高配水效率的关键策略。本文介绍了一种可与现有电子水表集成的无线收发器装置。该装置利用可靠的通信算法进行实时数据交换。计量数据采用尖端的窄带物联网技术进行传输,该技术使用低功耗,同时覆盖范围广,穿透力强。

There are several causes of hemolytic diseases, such as viral or bacterial contamination, enlarged spleen, and typhoid fever, which can be transmitted through contaminated water. Polluted wastewater samples were collected for the period of June-2022 to (May-2023) from five stations in Baghdad City such as Al- Gureat, Al-Ahdamyah, Bab Al-Muhadum, Bab Al-Sharqy and Al-Jadryah stations on the Tigris Riverbanks for the studying of Ceftriaxone antibiotic risk. The concentrations of ceftriaxone have been detected using high-performance liquid chromatography (HPLC). The results reveal that concentrations of ceftriaxone in the water fluctuated via sampling stations and seasons; so the highest concentration was 8 × 10-5 ppm in site 2 at Ahdamyah station, while the lowest concentrations was 1 × 10-7 ppm in site 5 sites at Al-Jadryah station during wet season 2023. The results of the statistical analysis showed that there were no significant differences between the study stations, except for the control station. The detection of ceftriaxone in raw surface water confirms that sewage from health institutions reaches the river without any effective treatment.
导致溶血性疾病的原因有多种,如病毒或细菌污染、脾脏肿大、伤寒等,这些疾病都可以通过受污染的水传播。为研究头孢曲松抗生素风险,从 2022 年 6 月至(2023 年 5 月)期间在巴格达市底格里斯河岸的 Al-Gureat、Al-Ahdamyah、Bab Al-Muhadum、Bab Al-Sharqy 和 Al-Jadryah 等五个站点收集了污染废水样本。采用高效液相色谱法(HPLC)检测头孢曲松的浓度。结果显示,在 2023 年雨季期间,水中头孢曲松的浓度随采样点和季节的变化而波动;因此,在 Ahdamyah 站的 2 号采样点,头孢曲松的浓度最高,为 8 × 10-5 ppm,而在 Al-Jadryah 站的 5 号采样点,头孢曲松的浓度最低,为 1 × 10-7 ppm。统计分析结果表明,除对照站外,各研究站之间没有显著差异。在地表原水中检测到头孢曲松证实,卫生机构的污水未经任何有效处理就流入河流。

Arsenic significantly impacts human health and the environment and its removal from wastewater is still difficult. Magnetic nanoparticles have come to light as a viable arsenic remediation technique, providing a fresh and long-lasting water purification method. This study investigates the use of magnetic nanoparticles to remove arsenic by concentrating on their adsorption mechanism, kinetics, potential for adsorption, recovery, and promising use of this method in the future. Due to the extensive surface area and variable surface chemistry of magnetic nanoparticles, they can effectively adsorb arsenic from water sources. Because their magnetic properties simplify separation and regeneration, they may be used again with little to no efficiency loss. As a result, they reduce trash output by providing an ecologically acceptable alternative to traditional adsorbents. The present study also examines the kinetics and adsorption process of magnetic nanoparticles, emphasising their improved selectivity and capacity for adsorption. Due to these characteristics, the authors were able to successfully remove arsenic from wastewater, resulting in better water quality and decreased health hazards after exposure to arsenic. Additionally, the potential applications of magnetic nanoparticles in removing arsenic have been highlighted. It is envisaged that advances in material science and nanotechnology will create unique magnetic nanoparticles with even better performance. Combining hybrid materials and surface alterations can increase their effectiveness in wastewater treatment settings.
砷严重影响人类健康和环境,而从废水中去除砷仍然十分困难。磁性纳米粒子作为一种可行的砷修复技术,为人们提供了一种全新而持久的水净化方法。本研究通过集中研究磁性纳米粒子的吸附机理、动力学、吸附潜力、回收率以及该方法在未来的应用前景,对利用磁性纳米粒子去除砷进行了研究。由于磁性纳米粒子具有广泛的表面积和可变的表面化学性质,因此可以有效地吸附水源中的砷。由于它们的磁性简化了分离和再生过程,因此再次使用时几乎不会降低效率。因此,纳米颗粒是一种生态上可接受的传统吸附剂替代品,可减少垃圾产量。本研究还对磁性纳米粒子的动力学和吸附过程进行了研究,强调它们具有更好的选择性和吸附能力。基于这些特性,作者能够成功去除废水中的砷,从而改善水质,减少接触砷后对健康的危害。此外,作者还强调了磁性纳米粒子在去除砷方面的潜在应用。预计材料科学和纳米技术的进步将创造出性能更优的独特磁性纳米粒子。将混合材料和表面改变结合起来,可以提高它们在废水处理环境中的有效性。

Records of precipitation and soil temperature, two of the most significant climatic elements impacting vegetation cover, were gathered as annual and monthly data over a period of 20 years from the European Center for Long-term Numerical Weather Forecasts. The goal of this study was to ascertain the impact of plant cover on climatic variations. The study’s final findings revealed that Mosul station had the greatest value of vegetation at 0.24 and Basra station had the lowest value at 0.15. The Mosul station recorded the maximum amount of precipitation, 1400 mm in the northern and central parts during the winter, and the lowest amount, 8 mm, during the fall and summer months in the districts west of the Rutba station. Using the Pearson test, it was discovered that the relationship between vegetation cover and soil temperature is inverse, and this, in turn, plays a significant role in the lack of vegetation cover in the southern regions because of nature. The desert of the region, as well as the lack of precipitation and high temperatures, is responsible for the region’s lack of vegetation. The highest value reached by the soil temperature was in the year 2018 at the Basra station.
降水量和土壤温度是影响植被覆盖的两个最重要的气候要素,欧洲长期数值天气预报中心收集了这两个要素 20 年来的年度和月度数据。这项研究的目的是确定植物覆盖对气候变化的影响。研究的最终结果显示,摩苏尔站的植被值最大,为 0.24,巴士拉站的植被值最小,为 0.15。摩苏尔站北部和中部地区冬季降水量最大,为 1400 毫米,鲁特巴站以西地区秋季和夏季降水量最小,为 8 毫米。通过皮尔逊检验发现,植被覆盖率与土壤温度之间存在反比关系,这也是南部地区植被覆盖率不足的重要原因。该地区的沙漠以及降水不足和气温偏高是造成该地区植被缺乏的原因。土壤温度的最高值出现在 2018 年的巴士拉站。

The presence of organophosphorus contaminants (OPCs) in water is a major concern due to their toxicity and adverse effects on human health and the environment. Traditional water treatment methods such as coagulation, sedimentation, and filtration are not always effective in removing OPCs from water, making it necessary to explore alternative methods. Nanomaterials, due to their unique physical, chemical and biological properties, have emerged as promising adsorbents for the removal of OPCs from water. This review article focusses on the recent developments in the use of nanomaterials as adsorbents for the removal of OPCs from water. The article covers various types of nanomaterials, including carbon-based nanomaterials, metal-based nanomaterials and other hybrid nanomaterials. The mechanisms of OPC adsorption by nanomaterials, such as electrostatic interactions, hydrogen bonding, and Van der Waals forces, are also discussed. The article further highlights the factors affecting the adsorption capacity of nanomaterials, such as pH, temperature, and concentration of OPCs. Additionally, the article examines the challenges associated with the application of nanomaterials in water treatment, such as the potential release of nanomaterials into the environment and the need for cost-effective and scalable synthesis methods.
由于有机磷污染物(OPCs)的毒性及其对人类健康和环境的不利影响,水中存在有机磷污染物已成为人们关注的主要问题。传统的水处理方法,如混凝、沉淀和过滤,并不总能有效去除水中的 OPC,因此有必要探索替代方法。纳米材料因其独特的物理、化学和生物特性,已成为去除水中 OPCs 的理想吸附剂。这篇综述文章重点介绍了使用纳米材料作为吸附剂去除水中 OPC 的最新进展。文章涉及各种类型的纳米材料,包括碳基纳米材料、金属基纳米材料和其他混合纳米材料。文章还讨论了纳米材料吸附 OPC 的机理,如静电相互作用、氢键和范德华力。文章进一步强调了影响纳米材料吸附能力的因素,如 pH 值、温度和 OPC 的浓度。此外,文章还探讨了与纳米材料在水处理中的应用相关的挑战,如纳米材料可能释放到环境中,以及需要具有成本效益和可扩展的合成方法。

However, the depletion of fresh water supplies as a result of climate change, as well as the rising demand associated with population increase, are some growing concern in many regions globally. Monitoring water distribution and delivery is a critical strategy for increasing distribution efficiency. This paper presents a wireless transceiver unit that can be integrated with existing electronic water meters. The unit utilises a reliable communication algorithm for real-time data exchange. Metering data is transmitted using cutting-edge narrow-band Internet of Things technology that operates using low power whilst covering a wide range with effective penetration.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139798313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of organophosphorus contaminants (OPCs) in water is a major concern due to their toxicity and adverse effects on human health and the environment. Traditional water treatment methods such as coagulation, sedimentation, and filtration are not always effective in removing OPCs from water, making it necessary to explore alternative methods. Nanomaterials, due to their unique physical, chemical and biological properties, have emerged as promising adsorbents for the removal of OPCs from water. This review article focusses on the recent developments in the use of nanomaterials as adsorbents for the removal of OPCs from water. The article covers various types of nanomaterials, including carbon-based nanomaterials, metal-based nanomaterials and other hybrid nanomaterials. The mechanisms of OPC adsorption by nanomaterials, such as electrostatic interactions, hydrogen bonding, and Van der Waals forces, are also discussed. The article further highlights the factors affecting the adsorption capacity of nanomaterials, such as pH, temperature, and concentration of OPCs. Additionally, the article examines the challenges associated with the application of nanomaterials in water treatment, such as the potential release of nanomaterials into the environment and the need for cost-effective and scalable synthesis methods.
由于有机磷污染物(OPCs)的毒性及其对人类健康和环境的不利影响,水中存在有机磷污染物已成为人们关注的主要问题。传统的水处理方法,如混凝、沉淀和过滤,并不总能有效去除水中的 OPC,因此有必要探索替代方法。纳米材料因其独特的物理、化学和生物特性,已成为去除水中 OPCs 的理想吸附剂。这篇综述文章重点介绍了使用纳米材料作为吸附剂去除水中 OPC 的最新进展。文章涉及各种类型的纳米材料,包括碳基纳米材料、金属基纳米材料和其他混合纳米材料。文章还讨论了纳米材料吸附 OPC 的机理,如静电相互作用、氢键和范德华力。文章进一步强调了影响纳米材料吸附能力的因素,如 pH 值、温度和 OPC 的浓度。此外,文章还探讨了与纳米材料在水处理中的应用相关的挑战,如纳米材料可能释放到环境中,以及需要具有成本效益和可扩展的合成方法。

Records of precipitation and soil temperature, two of the most significant climatic elements impacting vegetation cover, were gathered as annual and monthly data over a period of 20 years from the European Center for Long-term Numerical Weather Forecasts. The goal of this study was to ascertain the impact of plant cover on climatic variations. The study’s final findings revealed that Mosul station had the greatest value of vegetation at 0.24 and Basra station had the lowest value at 0.15. The Mosul station recorded the maximum amount of precipitation, 1400 mm in the northern and central parts during the winter, and the lowest amount, 8 mm, during the fall and summer months in the districts west of the Rutba station. Using the Pearson test, it was discovered that the relationship between vegetation cover and soil temperature is inverse, and this, in turn, plays a significant role in the lack of vegetation cover in the southern regions because of nature. The desert of the region, as well as the lack of precipitation and high temperatures, is responsible for the region’s lack of vegetation. The highest value reached by the soil temperature was in the year 2018 at the Basra station.
降水量和土壤温度是影响植被覆盖的两个最重要的气候要素,欧洲长期数值天气预报中心收集了这两个要素 20 年来的年度和月度数据。这项研究的目的是确定植物覆盖对气候变化的影响。研究的最终结果显示,摩苏尔站的植被值最大,为 0.24,巴士拉站的植被值最小,为 0.15。摩苏尔站北部和中部地区冬季降水量最大,为 1400 毫米,鲁特巴站以西地区秋季和夏季降水量最小,为 8 毫米。通过皮尔逊检验发现,植被覆盖率与土壤温度之间存在反比关系,这也是南部地区植被覆盖率不足的重要原因。该地区的沙漠以及降水不足和气温偏高是造成该地区植被缺乏的原因。土壤温度的最高值出现在 2018 年的巴士拉站。
