摘要

奥莫河流经奥莫雷特镇,该镇及其周边地区的生活、市政和工业废物(包括农用化学品)被排入河中。本研究旨在确定奥莫河下游淡水生态系统(水和沉积物)中的重金属含量及其对环境和人类健康的影响。河水中检测到的重金属平均浓度为 0.439 毫克/升(锰)、0.1 毫克/升(锌)、0.168 毫克/升(铜)、0.393 毫克/升(铬)、0.318 毫克/升(铅)、0.007 毫克/升(镍)、8.926 毫克/升(铁)和 0.06 毫克/升(钴)。HPI 值表明所有采样点都受到了严重污染。儿童和成人的口服和皮肤接触 HQ 值依次为 Cr > Pb > Mn > Fe > Cu > Co > Ni > Zn。经调查,儿童和成人从河水中通过摄入和皮肤途径摄入铬、铅和锰的 HQ 值均大于 1。儿童和成人摄入河水的 CR 值依次为 Cr > Pb。根据 CRI 值,河水可归类为极高环境风险。在沉积物中检测到的重金属的 EI 结果也遵循以下顺序:铁 > 铬 > 铜 > 铅:铁 > 铬 > 铜 > 铅 > 锰 > 钴 > 锌 > 镍。

Heavy Metal Contamination in Omo River, Ethiopia: Environmental and Human Health Risks.

The Omo River flows through the town of Omorate, where domestic, municipal, and industrial wastes from the town and its surroundings, including agrochemicals, are discharged into the river. The present study was conducted to determine the levels of heavy metals and associated environmental and human health impacts from the Lower Omo River freshwater ecosystem (water and sediment) of the Lower Omo River. The mean concentrations of heavy metals detected in the river water were 0.439 mg/l for (Mn), 0.1 (Zn), 0.168 (Cu), 0.393 (Cr), 0.318 (Pb), 0.007 (Ni), 8.926 (Fe), and 0.06 (Co).The order for the mean concentrations of the heavy metals in the water was Fe > Mn > Cr > Pb > Cu > Zn > Cu > Co > Ni. The HPI value indicates that all water sampling sites were highly contaminated. Oral and dermal HQs for both children and adults were in the order of Cr > Pb > Mn > Fe > Cu > Co > Ni > Zn. The HQ value greater than 1 was investigated for Cr, Pb, and Mn in both children and adults by ingestion and dermal routes from the river water. The CRs for both children and adults by ingestion of the river water followed the order Cr > Pb. According to the CRI value, the river water could be classified as a very high environmental risk. The EI results for the heavy metals detected in the sediments also followed the order: Fe > Cr > Cu > Pb > Mn > Co > Zn > Ni.
