西藏羊卓雍措水体重金属空间分布特征与健康风险评估

Spatial distribution characteristics and health risk assessment of heavy metals in Yamdrok Lake,Tibet

为探究羊卓雍措水体重金属污染特征及其对人体的危害程度,于2018,2019年内分5次采集26个采样点的130个水样,对水样中的Cr,Co,Cu,Fe,Cd,Sb,Ba,Pb,As等9种重金属进行检测分析,并采用美国环境保护署推荐的健康风险评价模型评价羊卓雍措的潜在健康风险。研究结果可以为当地水资源管理部门今后在水资源有效利用与饮用水安全管理方面提供参考。
