HM contamination issue is increasing all over the world in every component of the environment including groundwater resources. Heavy metals, such as Cd, Cu, Pb, Cr, and Hg are major pollutants that contaminate water used for drinking and agricultural purposes. Plants growing on HM‐polluted sites take in this contaminated water and accumulate HM in them and when these plants are used as food, these HM are transferred to the organism's bodies accumulating again [43]. Once fresh water organisms are exposed to HMs, like Cr, Ni, Cd, and Pb, accumulation is increased with increased exposure time, harming the consumer's kidneys and other body organs [47]. Food crops consumption that are irrigated with HM‐contaminated water is also a major route of human exposure to HM [48, 49]. Metals are being utilized in a range of ways in industries and agriculture; particularly heavy metals such as Hg, Cd, Pb, and As. These constitute a significant potential threat to human health via contaminated water [50]. Water pollution remains a major source of morbidity and mortality in different parts of the world. Water environment treatment has led to improved health outcomes among Chinese people. Reduced water pollution mediated the associations between water environment treatment and health outcomes [51].
