Access to safe drinking water and the wide spread of water-borne diseases are major challenges in Sub-Saharan Africa and Madagascar. Based on this, a water purification models has been developed which can use on a local scale. It consists of an intermittent biosand filter amended with oyster shell powders designed from local materials. The performance of the filter was evaluated through physicochemical and bacteriological analyses using standardized methods on raw polluted well water with previously determined initial D0 characteristics. The effectiveness of the designed filter was assessed and a filtration operation was carried out over a monitoring period of 13 days (D13) prior to 7 days of acclimatization of the system. With a filtration rate of 0.75l/h-1, there is a very strong reduction in turbidity from 35.59NTU to 0 NTU and in BOD5 from 125mg/l to 2mg/l. More so, bacteriological analyses reveal a progressive and complete decrease from D0 to D13 of fecal coliforms from 9000 CFU/100ml to 0 CFU/100ml; total coliforms from 6,000 CFU/100 ml to 0 CFU/100 ml and fecal streptococci from 10,800 CFU/100 ml to 0 CFU/100 ml. Compared to the classic ceramic filter, no significant difference in the Duncan test is reported for the highlighted parameters. This filter presents potential among other water treatment methods at the local scale for reducing the risks of water-borne diseases and achieving Sustainable Development Goal 6 in developing countries.

Noise pollution is one of the more prevalent types of pollution caused mainly by urbanization. It is characterized as noise propagating throughout a living being in a way that is to its physical and mental health. Along with the growth of the city, trade, business, shopping, education, and other activities have been accelerating. The main purpose of the study was to address the dangerous point of noise pollution in Dinajpur municipality and identify the causes of noise pollution. For this study, data sets on the amount of noise pollution at 35 different places throughout Dinajpur city have been analyzed. Three shifts of data collection were conducted: morning (8 am to 10 am), afternoon (12 pm to 2 pm) and evening (4.00 pm-6.00 pm). Using the ArcGIS 10.8 program, descriptive statistics tools and analysis of variance were carried out. The highest average noise level (105.7 dB) was found at Central Bus Terminal at the time of evening which is a mixed zone. The lowest average noise level (64 dB) was found at Chotogurgola and Balubari at the time of morning and evening respectively which is residential zone. The noise levels throughout the city vastly exceed both the WHO and DoE recommendations. The main causes of noise pollution are the expanding urban area, unregulated auto rice mills establishment, the heavy use of construction equipment, automobile engines, uncontrolled horns, and outrageous auto rickshaws etc. It is vital to take action to lower noise levels because prolonged exposure to noise has numerous negative effects. The development of comprehensive land use plans for this city would benefit from taking noise pollution into consideration.

Water treatment chemicals (WTCs) are important raw materials during the drinking water production process. Occasionally unqualified WTCs with heavy metals were provided to Water Treatment Plant（WTP） by supplier during emergency situation，such as earthquake, typhoon and city block for epidemic disease, just because it cannot obtain the qualified WTCs. The harmful heavy metals in WTCs may expose a certain health risk to the quality of drinking water. In this paper, the influence of heavy metals in WTCs on the quality of drinking water was explored and the feasible management measures are proposed, taking the ILha Verda Water Plant (IVP) in Macao as an example. The study was based on the testing results of heavy metals in WTCs and treated water from 2017 to 2022 in IVP. A series of mathematical models were established to evaluate the content of heavy metals in water brought by WTCs. The removal rates of the water treatment process to the heavy metals were calculated at same time. The maximum allowable concentrations of heavy metals in WTCs were calculated and accessed. The results show that the drinking water is safety if the heavy metals in unqualified WTCs are under the maximum allowable concentrations. Then it is proposed for the classification of WTCs and risk management. The study will provide theoretical and technical support for water quality safety supervision and water supply management.

This study was carried out to assess the groundwater quality around the Mogadishu area, Banadir region, Somalia. Multivariate statistical techniques such as factor analysis (FA), principal component analysis (PCA) and cluster analysis (CA)were applied to 22 groundwater samples collected from boreholes and dug wells in the coastal line districts namely: Wadajir, Kaxda and Dharkinley districts of Banadir region, Somalia. Correlations among 14 hydrochemical parameters were statistically examined. A two-factor model is suggested and explains over 82.4% of the total groundwater quality variation. Factor Analysis (FA) revealed significant variables including electrical conductivity (EC), pH value and other parameters such as K+, Ca2+, Mg2+, Na+, SO42- and hardness expressed as CaCO3, Chlorine, Fluoride, B, S, Si, and NO3 which are responsible for variations in groundwater quality and affect water chemistry. The results were compared with the World Health Organization (WHO) standard guidelines. Geographic Information System (GIS) was used to create the spatial distribution maps of water quality parameters. Cluster Analysis (CA) grouped all sites into three zones based on spatial similarities and dissimilarities of physiochemical properties. The pH value and Boron, fluoride calcium, magnesium, sulfide, potassium, and Silica are well within the desirable limit at all locations. However, the concentration of conductivity chloride, hardness as CaCO3, sulfate, nitrate, and Sodium in all samples exceeded the desirable WHO maximum permissible limit. The study reveals that the groundwater quality changed due to anthropogenic and natural influences such as natural weathering processes. As a result of this the qualities of the boreholes and dug well water samples were therefore not suitable for human consumption without adequate treatment. Regular monitoring of groundwater quality, abolishing unhealthy waste disposal practices, and introducing modern techniques are recommended.

The amount of clinical solid waste generated at Juba Teaching Hospital has been increasing as a result of the increasing population of Juba city. Despite the increase in the amounts of clinical solid waste, few scientific studies were conducted and the studies focused only on municipal solid waste management and have not explored clinical solid waste management in Juba City. A survey study aimed to explore the current methods and challenges of clinical solid waste management (CSWM) at Juba Teaching Hospital was conducted. The data was obtained through questionnaires, observation and oral interview. Word-excel-2013 and Statistical Package for Social Sciences (SPSS) IBM – 2021 version were used to process the data. The results revealed inappropriate methods of clinical solid waste management practices such as irregular collection, mixing different types of solid wastes together, use of water bottles instead of safety boxes for segregation of sharps, manual transportation of solid wastes, unprotected storage site, irregular incineration, open burning and random dumping. Reasons such as insufficient equipment, negligence of hospital administrators and few numbers of waste collectors was attributed to the inappropriate management of clinical solid waste in the hospital. The study recommended adoption of recycling strategies, employment of more waste handlers, commensurate remuneration and motivation, provision of enough equipment, creation of staff awareness and capacity development on health implications of poor clinical solid waste management.
随着朱巴市人口的增加，朱巴教学医院产生的医疗固体废物量也在不断增加。尽管临床固体废物的数量有所增加，但进行的科学研究却寥寥无几，而且这些研究仅侧重于城市固体废物管理，并未对朱巴市的临床固体废物管理进行探讨。我们开展了一项调查研究，旨在探索朱巴教学医院临床固体废物管理 (CSWM) 的当前方法和挑战。数据通过问卷调查、观察和口头访谈获得。数据处理使用了 Word-excel-2013 和 IBM - 2021 版社会科学统计软件包 (SPSS)。结果显示，临床固体废物管理方法不当，如收集不规范、将不同类型的固体废物混在一起、使用水瓶而不是安全箱来隔离利器、人工运输固体废物、储存地点无保护、焚烧不规范、露天焚烧和随意倾倒。设备不足、医院管理人员疏忽和废物收集人员数量少等原因是造成医院临床固体废物管理不当的原因。研究建议采取回收策略，雇用更多的废物处理人员，给予相应的报酬和激励，提供足够的设备，提高员工对不良临床固体废物管理对健康影响的认识和能力。
