Assessment of Heavy Metal Profile in Commercially Packaged Water in Ado Metropolis, Ekiti State, Nigeria

Commercially packaged water has been the main source of water supply to residents of Ado Metropolis; due to lack of potable water supply, individuals depend on commercial packaged water for drinking and domestic use. As a result of this, one has little or no assurance on the quality and safety of the water and its source. Heavy metal contamination includes exposure to lead, mercury, arsenic and cadmium, heavy metal contamination in Ado metropolis includes anthropogenic sources which includes activities of mining industries as discharge their untreated effluents into nearby water sources, other source of contamination includes automobile source that releases zinc, arsenic and copper; insecticides which releases arsenic and burning of fossil fuels which releases nickel, vanadium and mercury. Heavy metals cause general body weakness, abdominal pain, shortness of breath, chills, diarrhea, vomiting and tingling in the hands and feet when consumed. Hence, this study is important because it will reveal the presence of heavy metals in sampled waters in Ado Metropolis and also compare with WHO standard which in turn gives room for the suggestion of mitigating measures to regulate the sale of these public waters. Some brands of commercially packaged were purchased from different markets in Ado metropolis based on accessibility and high demands.
