Abstract

This study was undertaken to determine the possible health risk associated with raw wastewater use in agricultural purposes, particularly, the transmission of parasite infections among children of five regions in Beni-Mellal, Morocco. In a randomly-selected sample of 1343 children, 740 of them were from five regions using raw wastewater for agriculture, and 603 were from 4 control regions that do not practice wastewater irrigation. One or more parasite infections were identified in 50.8% of the children living in the wastewater re-use regions and in 8.2% only of the others. The seven parasites identified were Entamoeba histolytica, Giardia intestinalis, Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Hymenolepis nana, Taenia saginata, which infected 34.3%, 5.1%, 20.5%, 0.4%, 5.2%, 7.2%, 0.5% in the exposed population and 4.3%, 0.3%, 3.8%, 0.3%, 1.0%, 0.6% and 0.0% in the control population respectively. In conclusion, raw wastewater use in Beni-Mellal lead to a high risk of parasite infections. Adequate treatment of wastewater is highly recommended.

摘要

本研究旨在确定农业使用未经处理的废水可能带来的健康风险，特别是摩洛哥贝尼-梅勒五个地区儿童中寄生虫感染的传播情况。在随机抽取的1343名儿童样本中，其中740名来自使用未经处理的废水进行农业生产的五个地区，603名来自不进行废水灌溉的4个对照地区。生活在废水再利用地区的儿童中，50.8%被查出感染了一种或多种寄生虫，而在其他地区的儿童中这一比例仅为8.2%。鉴定出的七种寄生虫为溶组织内阿米巴、肠贾第虫、蛔虫、鞭虫、蛲虫、微小膜壳绦虫、牛带绦虫，在暴露人群中的感染率分别为34.3%、5.1%、20.5%、0.4%、5.2%、7.2%、0.5%，在对照人群中的感染率分别为4.3%、0.3%、3.8%、0.3%、1.0%、0.6%和0.0%。总之，贝尼-梅勒地区使用未经处理的废水会导致寄生虫感染的高风险。强烈建议对废水进行充分处理。
