Pinyari (old Phulleli) canal off-takes from left bank of Kotri barrage is last Hydraulic structure on Indus river. This canal is passing from periphery of Hyderabad city and its design discharge is 13,636 cusecs which supplies fresh water not only for agricultural, industrial purpose and drinking purpose for the several towns and villages because groundwater in its command area is highly saline and not drinkable. The cottage factories and Hyderabad industrial area are located on nearby banks of canal. Hence, effluents from city and industrial SITE area are directly disposed off into the canal. The disposal of untreated wastewater created health and environmental safety problem. This paper presents that the analyzed results of water quality parameter ie pH, TDS, EC, Na, hardness, K, Mg, Mn, DO and BOD of collacted samples exhibit TDS 6%, K 20%, DO 67% and BOD 54%, respectively exceeded permissible limit. While pH, Na, hardness and Mn found within prescribed limits. Total coliform /E.coli (MPN/100ml) were found positive. Furthermore, the result of Water Quality Index (WQI) model reveals that water quality of canal of collected samples varies from excellent to very poor that reveals canal water is unsuitable for drinking purpose and aquatic life and also causes various waterborne diseases. Therefore, the local people are facing serious health problem by consuming water canal. With an attempt to ensure enforcement of environmental water laws in Sindh province of Pakistan for preventing degrading clean water. These environmental water laws have already been framed, but due to lake of enforcement, water pollution problems are increasing day by day. The enforcement of environmental water laws are very essential to control water pollution for safety of human health, and ecology in Sindh, Pakistan.
Pinyari(旧Phulleli)运河从Kotri拦河坝左岸出发,是印度河上最后一个水力结构。这条运河从海得拉巴市的外围通过,其设计流量为13636立方米,不仅为农业、工业和几个城镇和村庄提供淡水,因为其指挥区域的地下水含盐量高,不能饮用。村舍工厂和海得拉巴工业区位于附近的运河岸边。因此,城市和工业场地的污水直接排入运河。未经处理的废水的处理造成了健康和环境安全问题。对采集样品的水质参数pH、TDS、EC、Na、硬度、K、Mg、Mn、DO和BOD的分析结果显示,TDS、k20%、DO和BOD分别超过允许范围6%、67%和54%。pH、Na、硬度、Mn均在规定范围内。总大肠菌群/E。大肠杆菌(MPN/100ml)阳性。此外,水质指数(WQI)模型的结果显示,所采集样本的运河水质从优良到极差,表明运河水不适合饮用和水生生物,并引起各种水传播疾病。因此,当地居民因饮用水渠而面临严重的健康问题。试图确保巴基斯坦信德省环境水法的执行,以防止清洁水的退化。这些环境水法已经制定,但由于执行不力,水污染问题日益严重。在巴基斯坦信德省,环境水法的执行对于控制水污染、保障人类健康和生态安全至关重要。

This study aims to make adsorption-capable zeolite from coal fly ash, a waste product from coal-fired power plants (CFA). When it comes to commercializing sorbent, the total cost and efficiency of the adsorbent material are critical. This work used tap water instead of distilled water (DW) to synthesis zeolite from fly ashes at 90°C crystallization temperatures. The discovery lays the door for a cost-effective but easy technique of synthesizing viable zeolitic materials for adsorption applications using waste products like coal fly ash. According to the comprehensive characterization, the support for the use of TP to make zeolites is based on its larger particle size, and lower carbon impurities. The generated zeolite was homogenous and A-type, and applied as an adsorbent to remove traces of heavy metals contaminants. During a 25-minute agitation period, the zeolites produced with TP had a greater adsorption capacity. In principle, the proposed approach permits the synthesis of low-cost, high-efficiency zeolite-based adsorbent materials for environmental remediation without the use of harmful or expensive chemicals.
本研究旨在利用燃煤电厂的废弃物粉煤灰制备具有吸附性能的沸石。当涉及到吸附剂的商业化,吸附剂材料的总成本和效率是至关重要的。本研究以自来水代替蒸馏水,在90℃结晶温度下由粉煤灰合成沸石。这一发现为一种经济而简单的技术铺平了道路,即利用粉煤灰等废物合成可行的沸石吸附材料。综合表征可知,TP粒径较大,碳杂质较低是其制备沸石的支撑。所得沸石为均质a型沸石,可作为吸附剂去除痕量重金属污染物。在25分钟的搅拌时间内,TP制备的沸石具有更大的吸附能力。原则上,所提出的方法允许合成低成本、高效率的沸石基吸附材料,用于环境修复,而不使用有害或昂贵的化学品。

The study area is located in the south-western coastal part of Bangladesh and belongs to the lower deltaic plain of the Ganges delta system, which lies in the Rampal upazila of Bagherhat district. The area is more or less flat with elevation ranges from 1.0 to 2.0 m above mean sea level (MSL) and is blanketed with fluvio-tidal deposits of sandy silt, clayey silt and clay. Right now, water logging is one of the major problems in the area. The present paper is an attempt to expose the causes of water logging as well as its consequences. The satellite images of the last few decades, existing statistical records and simultaneous field checking were employed in this study, which reveals that natural as well as anthropogenic factors are responsible for water logging problem. The rivers and their link channels in the areas are influenced by tidal water regularly. The Water Development Board (WDB) was built embankments along the river courses as well as constructed sluice gates on the head of the tidal creeks to protect the area from regular tidal flooding and sea water intrusion. During monsoon, when rivers carry huge amount of water and sediments due to torrential rain, and these rising waters overtop the natural levees which were artificially modified and raised by coastal embankments. Consequently, the sediments drop down inside the channel and near channel bank rather in the nearby tidal plain. As a result, channels are gradually congested due to siltation, whereas tidal plain areas gradually lower due to subsidence and lack of sedimentation. Moreover, many sluice gates were constructed on the river courses in the coastal areas which also aggravate the situation. Daudkhali river is one of the main rivers in the study area. Image interpretation depicts that in 1977 the width of this river was nearly about 200 m all through its course and the river maintained this width up to 1990. But due to embankments the river starts to squeeze and the width of the river reached about 100 m in 2000. But in 2014, the river was nearly abandoned. A sluice gate was constructed on the course of the river about 30 years ago near Foila Bazar. The sediments carried by the river started to deposit in the mouth of the sluice gate which gradually choked the opening of the gate and now the gate is nearly blocked. During the rainy season, the river cannot carry excess water resulting flooding and water logging for long time. The presence of thick finer sediments in the subsurface as well as climate change further prolongates the situations. Finally, for sustainable development of the area,it is necessary to carry out different development activities with consideration of delta building processes.
研究区位于孟加拉国西南沿海,属于恒河三角洲体系的下三角洲平原,位于Bagherhat地区的Rampal upazila。该地区地势较平坦,海拔高度在平均海平面以上1.0 ~ 2.0 m之间,覆盖着砂质粉砂、粘土粉砂和粘土的流潮沉积。目前,内涝是该地区的主要问题之一。本文试图揭示内涝的原因及其后果。利用近几十年的卫星影像、已有的统计记录和同时进行的实地核查,揭示了自然因素和人为因素对内涝问题的影响。该地区的河流及其连接河道经常受到潮汐的影响。水发展局(WDB)沿着河道修建了堤防,并在潮汐小溪的顶部建造了闸门,以保护该地区免受定期的潮汐洪水和海水入侵。在季风期间,由于暴雨,河流携带了大量的水和沉积物,这些上涨的水超过了由沿海堤防人工修改和抬高的天然堤防。因此,沉积物落在河道内和靠近河道岸边,而不是附近的潮汐平原上。因此,河道因淤积而逐渐淤塞,而潮平原地区则因沉降和缺乏淤积而逐渐降低。此外,在沿海地区的河道上修建了许多闸门,也加剧了这一情况。Daudkhali河是研究区内的主要河流之一。图像解译显示,1977年,这条河的整个河道宽度约为200米,直到1990年,这条河一直保持着这一宽度。但由于堤防,河流开始挤压,2000年河流宽度达到100米左右。但在2014年,这条河几乎被废弃了。大约30年前,在福伊拉巴扎尔附近的河道上修建了一个水闸。河水携带的泥沙开始在闸门口淤积,逐渐堵住了闸门的开口,现在闸门几乎被堵住了。在雨季,河流不能携带多余的水,导致洪水和内涝长时间。地下厚而细的沉积物的存在以及气候变化进一步延长了这种情况。最后,为了区域的可持续发展,有必要在考虑三角洲建设过程的情况下开展不同的开发活动。

Wetlands are the source of vital ecosystems which provide human societies with essential and extremely valuable life-supporting functions. The rapid population growth and resultant exploitation of lands, water bodies, and forests have badly influenced wetland resources. Wetlands are non-market goods as they do not have market value. So, it is important to evaluate these resources economically to identify their significance. Therefore, this study aims to identify the visitors’ willingness to pay for the economic valuation of Salt Range wetlands comprised of Kalar Kahar, Uchali, Jhalar, Khabeki, and Namal Lakes. A qualitative method was used to gather relevant information from the respondents by using a questionnaire. By applying the willingness to pay (WTP) technique it was found that about 85.34% of tourists were agreed to visit these lakes because of their naturalness. Similarly, the mean WTP in Kalar Kahar lake was PKR. 1808, in Uchali lakes was PKR.1820 while in Namal lake it was PKR. 1848. It is concluded that all the lakes are equally important and economically valuable for the tourists as there was a frictional difference in mean WTP. It is suggested that these lakes should be conserved for future generations to sustain the long-term economic benefits for the concerned stakeholders through the initiation of ecotourism.
湿地是重要生态系统的来源,为人类社会提供了基本和极其宝贵的维持生命的功能。人口的快速增长以及随之而来的对土地、水体和森林的开发已经严重影响了湿地资源。湿地是非市场商品,因为它们没有市场价值。因此,对这些资源进行经济评价以确定其重要性是十分重要的。因此,本研究旨在确定游客对由Kalar Kahar、Uchali、Jhalar、Khabeki和Namal湖泊组成的盐岭湿地的经济价值支付意愿。采用定性的方法,通过问卷调查的方式从受访者中收集相关信息。应用支付意愿(WTP)技术分析发现,85.34%的游客因其自然属性而同意游览这些湖泊。Kalar Kahar湖的平均WTP为PKR。1808年,在乌恰里湖是PKR.1820,而在纳马尔湖是PKR。1848. 结果表明,由于湖泊平均WTP存在摩擦差异,各湖泊对游客具有同等的重要性和经济价值。建议为子孙后代保护这些湖泊,通过开展生态旅游,为相关利益相关者维持长期的经济效益。

Climate Change in Bangladesh is an extremely crucial issue. Bangladesh is one of the worstly affected countries by the impacts of Climate Change in coming decades. The climate change in Bangladesh causes the degradation of land resources. High intensity and recurrence of floods are due to irregular rainfall and glacier melting of the Himalayas intensified river bank erosion throughout the year. High yielding land resources on the river bank are degraded each year. This study was conducted for riverbank shifting detection, morphodynamics assessment, and estimation of eroded and accreted land by the Jamuna river at Shahjadpurupazila, Sirajganj district, Bangladesh. The investigation is based on multispectral satellite imagery interpretations using ArcGIS software, followed by a field check. Interpretations show that the Jamuna river in the study area has continuously shifted its path from east to west from 1956 to 2020, resulting in a total loss of 51.68 km2 of landmass. The rate of engulfment was 0.95km2/year whereas the accretion rate was 0.15km2/year. The maximum rate of river shifting on the right bank of Jamuna river in the ShahjadpurUpazila is 84.38 meters/year and the minimum shifting is 31.25 meters/year. This study will help to understand the scenario of land degradation by river erosion in the study area. It may be also helpful to the decision-makers to take the proper mitigation measures regarding riverbank erosion and protection.
气候变化在孟加拉国是一个极其关键的问题。孟加拉国是未来几十年受气候变化影响最严重的国家之一。孟加拉国的气候变化导致了土地资源的退化。洪水的高强度和反复发生是由于不规律的降雨和喜马拉雅山的冰川融化加剧了全年的河岸侵蚀。河岸的高产土地资源每年都在退化。本研究对孟加拉国Sirajganj地区Shahjadpurupazila的贾穆纳河进行了河岸移动检测、形态动力学评估和侵蚀和淤积土地估算。调查基于使用ArcGIS软件的多光谱卫星图像解译,随后进行实地检查。解译结果表明,1956年至2020年,研究区内的贾穆纳河河道不断由东向西移动,共损失了51.68 km2的陆地面积。吞没速率为0.95km2/年,吸积速率为0.15km2/年。沙杰德普巴齐拉贾木纳河右岸的最大移河速率为84.38米/年,最小移河速率为31.25米/年。本研究将有助于了解研究区河流侵蚀导致土地退化的情景。针对河堤侵蚀和保护采取适当的缓解措施,对决策者也有一定的帮助。

High yielding land resources on the river bank are degraded each year. This study was conducted for riverbank shifting detection, morphodynamics assessment, and estimation of eroded and accreted land by the Jamuna river at Shahjadpurupazila, Sirajganj district, Bangladesh. The investigation is based on multispectral satellite imagery interpretations using ArcGIS software, followed by a field check. Interpretations show that the Jamuna river in the study area has continuously shifted its path from east to west from 1956 to 2020, resulting in a total loss of 51.68 km2 of landmass.

Mining is one of the oldest professions in history. Along with the development of human life, mines also give direction to civilization and the economy. Mining activities carry various risks in terms of occupational health and safety (OHS). These risks can be examined under the main headings of work accidents and occupational diseases. As a result, thousands of workers face illness and death every year. Additionally, economic losses occur as a result of production interruption and stopping. Despite all the efforts to reduce mining accidents, statistics show that underground mining is one of the riskiest among all working industries. It is seen that the physical risk factors encountered in the mining sector line are remarkable in terms of risk factors. Physical risk factors that may be encountered in mines are dust, noise, vibration, lighting problems, and thermal conditions. It is essential to take measures to assess these risks and ensure the comfort of employees where each physical risk factor needs to be examined separately. In this study, physical risks being frequently encountered in underground coal mines are taken into account with recommendations for the risks.
采矿是历史上最古老的职业之一。随着人类生活的发展,矿山也为文明和经济指明了方向。采矿活动在职业健康和安全方面存在各种风险。这些风险可以在工作事故和职业病的主要标题下进行审查。因此,每年有成千上万的工人面临疾病和死亡。此外,生产中断和停止也会造成经济损失。尽管为减少采矿事故做出了种种努力,但统计数据表明,地下采矿是所有工作行业中最危险的行业之一。可见,矿业板块线下遇到的物理风险因素在风险因素方面是显著的。矿井中可能遇到的物理危险因素有粉尘、噪音、振动、照明问题和热条件。必须采取措施评估这些风险,并确保员工的舒适度,其中每个身体风险因素需要单独检查。本研究考虑了煤矿井下经常遇到的物理风险,并提出了相应的风险建议。

Quality standards have been a significant achievement for organizations worldwide. Environmental standardsshould be established in hospitals by coding ISO14001. Hospital water pollution can cause health issues in nearby urbanareas and settlements. The study was aimed to estimate, characterize, use, and response to water quality parameters onamplification of environmental coordination at General Hospital Lahore (GHL), and their implications for evaluation inmanagement reviewing. For these purposes, the drinking water samples were collected from different locations in thestudy area. All these samples were analyzed for different water quality parameters namely, pH, TDS, turbidity, andchloride, and compared with national environmental quality standards (NEQS). All the results and management processeswere also compared with ISO 14001:2015, which indicated the weakness in the general administration framework andEnvironmental Management System (EMS). The results show that pH 8.6, TDS 1100 mg/l, turbidity 5.5 NTU, andchloride 260 mg/l were exceeding the maximum permissible limits. The present study recommended that GHL watershould be treated before its use/ disposal. In the end, an EMS (a policy with protocol) manual was developed for continualimprovement of water use. Drinking water quality assessment and EMS framework offer assistance to oversee the waterquality and environment in health centers. Drinking water quality management under the guidelines of the environmentmanagement system manual developed in this study will greatly help to manage the environment, particularly waterpollution in local hospitals of Pakistan.

The current environmental pollution has great impact on climate change and the present study was aimed at removal of sulfur as a pollutant for environment on combustion of kerosene fuel using clay, namely attapulgite and magnetic iron (ATP)-Fe3O4 nanocomposite. To lower the toxic sulfur and to enhance the property of reduced sulfur fuel specifically the electrical conductivity (EC) was also improved by the addition of quality improver additives. The (ATP)-Fe3O4 nanocomposite was synthesized by co-precipitation method and the structure, and morphology were evaluated using scanning electron microscopy (SEM), and fourier transform infrared spectroscopy (FT-IR). The average size of Fe-NPs which helps in the oxidative desulfurization was found to be <100 nm, and the toxic sulfur content in fuel was reduced up to 71% from its original using 05mg/mL of nanocomposite at 150°C for 30 min along with CH3COOH and H2O2 proceed with water washing. The EC of the oxidative desulfurized (ODS) fuel was enhanced by the addition of (0.5, 0.7 and 1.0ppm) STADIS 450 additive as compared to MEROX kerosene fuel (untreated). The ODS kerosene showed greater stability of EC over MEROX kerosene.
当前的环境污染对气候变化的影响很大,本研究旨在利用粘土即凹凸棒土和磁性铁(ATP)-Fe3O4纳米复合材料去除煤油燃料燃烧对环境的污染物硫。为了降低有毒硫,提高还原硫燃料的性能,还通过添加质量改良剂来改善其电导率。采用共沉淀法合成了(ATP)-Fe3O4纳米复合材料,并利用扫描电镜(SEM)和傅里叶变换红外光谱(FT-IR)对其结构和形貌进行了表征。结果表明,Fe-NPs的平均粒径小于100 nm,在150℃、CH3COOH和H2O2的作用下,用05mg/mL的纳米复合材料水洗30 min,可使燃料中有毒硫含量降低71%。与未处理的MEROX煤油相比,添加(0.5、0.7和1.0ppm) STADIS 450添加剂可提高氧化脱硫(ODS)燃料的EC。ODS煤油的EC稳定性优于MEROX煤油。
