Abstract: Heavy metals are normally occurring elements that have a density at least 5 times higher than of water. Their plentiful domestic, industrial, agricultural and technological usages have led to their widespread distribution in the environment; raising worries over their possible impacts on human health and the environment. The toxicity of heavy metals relies on numerous factors including the dose, method of exposure, and chemical types. This review provides an analysis of heavy metals occurrence, toxicity, and some pollution assessment methods such as the geoaccumulation index, contamination factor, Contamination Degree, Enirchment factor, pollution load index, Ecotoxilogical sense of heavy metals contamination and Risk Assessment of heavy metals consumption.
