Abstract

Background

Groundwater is a sustainable resource that provides potable water for millions of people. Contamination of groundwater by metals and metalloids (MMs) may, therefore, pose serious health threats to consumers.

Objective

This study aimed at assessing the health risk of MMs in groundwater resources around the vicinity of sanitation facilities at different markets in Abeokuta metropolis, southwestern Nigeria.

Methods

Fifty hand-dug wells around the waste sanitation facilities in ten markets from the Abeokuta metropolis were monitored. Groundwater samples were analysed for MMs using atomic absorption spectrophotometer. Data were subjected to descriptive and inferential statistics. Health risk assessment (non-carcinogenic hazard quotient [HQ], and cancer risk [CR]) were estimated in groundwater.

Results

Significantly higher (p<0.01) levels of MMs were observed in groundwater from the market areas than in the control site. The health risk assessment showed high HQs greater than the acceptable limit of 1.0 for Mn and Pb, establishing non-carcinogenic adverse health effects. Co also indicated carcinogenic effects in the groundwater from the market areas showing a CR value greater than the permissible limit of 1.0 × 10⁻⁴.

Conclusion

This study established the detrimental effects of market wastes on the surrounding groundwater quality.

尼日利亚西南部阿贝奥库塔大都市主要市场卫生设施周围地下水资源中金属和类金属的人类健康风险评估

地下水是一种可持续资源，为数百万人提供饮用水。因此，金属和类金属污染地下水可能对消费者的健康构成严重威胁。目的评价尼日利亚西南部阿贝奥库塔市不同市场卫生设施附近地下水资源中mm的健康风险。方法对阿贝奥库塔市10个市场垃圾环卫设施周围50口手挖井进行监测。采用原子吸收分光光度计对地下水样品中mm进行了分析。对数据进行描述性和推断性统计。对地下水进行了健康风险评价(非致癌危害系数[HQ]和致癌风险[CR])。结果市场区地下水中mm含量显著高于对照组(p < 0.01)。健康风险评估显示，高HQs值大于可接受的Mn和Pb限值1.0，建立了非致癌的不良健康影响。Co还指出，来自市场地区的地下水的致癌作用显示CR值大于允许限值1.0 × 10−4。结论本研究确定了市场废弃物对周边地下水水质的不利影响。
