ABSTRACT

This cross-sectional study was conducted to evaluate drinking water and wastewater management facilities, as well as the health risk associated with heavy metal contamination of available water sources among Badagry schools. According to Joint Monitoring Program classification, majority (60%) of the schools provided basic water service, 10% limited service, whereas 30% provided no service. Water quality parameters such as pH, Pb, Cr, Cd, and E. Coli count were above the permissible limits in both public and private schools. None of the schools had wastewater management facilities, thereby leading to ponding. Pb and Cr posed a carcinogenic risk to the consumers as they exceeded the permissible 10⁻⁵. Even though majority of the schools provided basic water service, the contamination of majority of the water sources and the absence of structured-drainage channels in all the schools was bothersome. Prompt intervention is required to safeguard and maintain the integrity of the students’ health.

摘要

这项横断面研究旨在评估巴达格里学校的饮用水和废水管理设施，以及与可用水源的重金属污染相关的健康风险。根据联合监测计划分类，大多数（60%）学校提供基本供水服务，10% 提供有限服务，而 30% 不提供服务。水质参数，如 pH、Pb、Cr、Cd 和大肠杆菌计数均高于公立和私立学校的允许限值。没有一所学校有废水管理设施，从而导致积水。^{铅和铬超过允许的 10 -5}对消费者构成致癌风险. 尽管大多数学校提供基本的供水服务，但大部分水源受到污染，而且所有学校都没有结构化的排水渠道，这令人烦恼。需要及时干预以保障和维护学生健康的完整性。
