This systematic review and meta-analysis estimated the pooled mean levels of heavy metals in ground and surface water samples obtained from the Niger Delta region of Nigeria (NDRN). PUBMED and Google Scholar databases were searched for studies published between 2000 and 2019, which assessed the levels of heavy metals in natural water samples obtained from the NDRN. Thirty one (31) studies which had a total of 951 water samples were identified. The pooled mean estimate (PME) from the meta-analysis indicates that the levels of Ni, Cd, Cr, and Pb in the majority of the natural water bodies from the NDRN are higher than the WHO safe permissible limit for drinking water. The contributions of prevailing anthropogenic activities to the observed heavy metal profiles of natural water sources from the NDRN were discussed. Stricter enforcement of safe environmental practices is necessary to protect the lives of the over 30 million inhabitants of this oil rich region.
本系统评价和荟萃分析估计了从尼日利亚尼日尔三角洲地区（NDRN）采集的地下水和地表水样本中重金属的平均含量。在 PUBMED 和 Google Scholar 数据库中检索了 2000 年至 2019 年期间发表的评估从 NDRN 采集的天然水样中重金属含量的研究。确定了 31 项研究，其中共有 951 个水样。荟萃分析的汇总平均值（PME）表明，NDRN 地区大多数天然水体中的 Ni、Cd、Cr 和 Pb 含量均高于世界卫生组织（WHO）饮用水安全允许限量。讨论了普遍存在的人为活动对 NDRN 天然水源中观察到的重金属分布的影响。为了保护这个石油资源丰富地区的 3000 多万居民的生命，有必要加强安全环境实践的执行力度。
