Introduction: The effluents generated by hospital activities pose a potential danger to health and the environment. This study aimed to study the microbiological quality of the effluents produced by the university and hospital centres of Littoral department. Methods: This was a descriptive cross-sectional study of 60 samples of hospital effluents from sewage treatment plants and septic tanks carried out during the period from April to June 2019. Samples at the station were made at the entrance and exit of the station. Samples for microbiological analysis were collected in pre-sterilized 500 mL glass bottles. Samples were kept between at 2°C - 8°C and in the dark to ensure satisfactory preservation. ANOVA one-way analysis of variance was performed for each microbiological parameter and principal component analysis (PCA) was also performed. Results: The bacteriological analyses carried out on the 60 samples taken showed a significant microbiological load. In fact, the bacteriological parameters measured and compared to the pollutant release standards in the environment show that the number of germs identified is above the recommended guideline values. The average values for total coliforms, faecal coliforms, faecal streptococci and staphylococci were: 3.91 × 105 UFC/100 mL, 0.52 × 105 UFC/100 mL, 3.92 × 105 UFC/100 mL and 1.36 × 105 UFC/100 mL, respectively. The most isolated bacteria were: Klebsiella pneumoniae, Klebsiella oxytoca, Escherichia coli, Enterococcus faecalis, Enterobacter cloacae, Pseudomonas horizyhabitans, Staphylococcus aureus and Staphylococcus saprophyticus. Most strains were resistant to at least 3 families of antibiotics (beta-lactams, aminoglycosides and fluoroquinolones). Conclusion: These effluents therefore present health and environmental risks. It is of utmost importance to develop methods for the treatment of these effluents before their release into the natural environment.

Introduction: Because of the specificity of their care activities, hospital wastewater contains various contaminants such as germs, disinfectants, metals, pharmaceuticals and chemical reagents, potentially infectious or toxic, which can be harmful to living organisms, or create ecological damage. This study aimed to analyze the quality of wastewaters produced by university hospitals of Cotonou in Benin. Methods: We conduct an analytical cross-sectional study including 30 wastewater samples from selected hospitals. An analysis of variance was performed at the significance level of 0.05. Results: Microbiological analysis showed the presence of germs such as total coliform types, faecal coliforms, fecal streptococcus, staphylococcus, yeasts and Clostridium perfringens in hospital wastewater samples. There was a significant difference (p lectrical conductivity of wastewater (p levels of metals detected in the wastewaters were in line with Benin’s standards. There was no difference between the average concentrations of metals except for copper (p Conclusion: The wastewater produced by the university hospitals of Cotonou is of poor quality and therefore requires adequate prior treatment before discharge into the environment.

地膜的大量使用会导致土壤微塑料(microplastics,MPs)和邻苯二甲酸酯(phthalate acid esters,PAEs)的污染,但较少有研究报道不同轮作模式对土壤中MPs丰度和形态分布的影响,同时MPs与PAEs之间在农业土壤中的相关性尚不清楚。本研究采集了邳州大蒜种植区内大蒜-玉米、大蒜-大豆和大蒜-水稻3种不同轮作模式下的土壤,采用激光红外成像系统对土壤中MPs的丰度、组成以及形态特征进行分析鉴定,并采用气相色谱-质谱联用法(GC-MS)法分析土壤中16种PAEs含量,结合土壤MPs丰度分析二者之间的相关性。结果表明,邳州大蒜种植区土壤MPs的平均丰度为4710.67个·kg^(-1),主要由聚酰胺(PA)、聚乙烯(PE)和聚氯乙烯(PVC)等类型组成,分别占比47.82%、13.94%和17.51%;MPs以碎片状为主,且超过75%的MPs粒径≤50μm。不同轮作模式下的MPs平均丰度差异明显,呈现大蒜-玉米土壤(5788.02个·kg^(-1))>大蒜-水稻土壤(4983.71个·kg^(-1))>大蒜-大豆土壤(3090.93个·kg^(-1))的趋势。大蒜-大豆土壤MPs的平均面积及高度和宽度等形态特征与大蒜-玉米土壤和大蒜-水稻土壤的MPs均存在显著差异。此外,土壤中的PAEs种类主要为邻苯二甲酸二(2-乙基己基)酯(DEHP)、邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二甲酯(DMP)。邳州大蒜种植区土壤中MPs总丰度与∑PAEs含量(R^(2)=0.68,P=0.0005)和DEHP含量(R^(2)=0.54,P=0.004)呈显著正相关。

Iron and Manganese contents and parameters including pH, conductivity, and organic matter contents were determined in the sediments of the Okpara dam in Northern Benin. Fifteen samples were collected during a one-month period and analysed in laboratory using the method of sequential extraction of Tessier. The analyses indicated that sediments contained high concentrations in reducible fraction of Iron and relatively high contents of exchangeable fraction, acidhydrolysable fraction and residual fraction of Manganese. The findings of this study confirmed the hypotheses that the meal contents of the sediments were relatively high and varied according to the geochemical phases.

由于人类活动和工业化的迅速发展,大量的有机氯农药被应用于农业。这些化学品在其生命周期中的不可持续管控,己导致环境土壤、地表水和地下水、生物群和人类受到广泛而严重的持续性有毒物质污染。农药废水的流出与积累到土壤,使土壤含有范围广而浓度极高的有机氯污染物。污染土壤问题是一个全球性环境问题,亟须解决。在目前的土壤修复应用中,电动修复技术处理清洗单一污染物合成的土壤己得到广泛的研究,但是该技术在实际污染场地土壤的应用上具有挑战性,有待更进一步地实践创新。[目的]本文旨在探讨非离子表面活性剂吐温80 （TW80）对电动一高级氧化修复有机氯农药污染场地土壤的增强效果,为解决实际污染场地土壤提供科学理论依据。[方法]采集湖北武汉某农药化工厂的污染场地土壤为供试土壤,分别研究10g/LTW80和20g/L过硫酸钠（NaSO,PS）作为不同溶剂/共溶剂的电动修复体系对场地污染土壤中11种有机氯苯化合物的降解效果。[结果]实验研究结果可知,TW80-PS作为共溶剂增强了电动一高级氧化,10天处理后均可从土壤中去除有机氯苯污染物约60%到80%（存在nZVI反应墙）。与空白组（没有TW80）相比,对应的增强幅度为20%—30%。这一性能归因于TW80一方面能够溶解低或难溶的化合物;另一方面通过溶解土壤自身的过渡金属离子（在不存在nZVI反应墙）来维持过硫酸根离子(SO～（2-）)的活化,这是维持硫酸根自由基(SO～（～-）)产生和污染物降解所必需的。[结论]表明（EK-TW80-PS-nZVI）是修复污染场地的最佳方法,TW80能够增强电动—高级氧化修复效果。
