REVIEW OF HEAVY METALS IN DRINKING WATER AND THEIR EFFECT ON HUMAN HEALTH

Abstract

The levels of heavy metal contamination in various water sources as ground, surface, tap water etc. collected from various water origins (sources) of particular area in the research work (papers) of respective authors mentioned. The authors respective of their work determined the heavy metal concentration with the help of standard literature procedures. The methods in their research work were Atomic Absorption spectroscopy, Differential Pulse Anodic Stripping Voltammetry (DPASV), samples acidified to 1% with nitric acid and then stored in Double capped polyethylene bottles. The determination of the (concentration of) heavy metals found in their research work were as, Cd, Cr, Cu, Fe, Pb, Co, Mn, Hg, Ni, Zn. The concentrations determined were more than the maximum admissible and desirable limit when compared with the National and International organizations like WHO (2008), USEPA, EUC, EPA . On account of the concentrations of heavy metals determined by the authors in their research work, the authors detected the adverse effects on human health. On account of the concentrations of the heavy metals(determined ) studied from their research papers , water samples are not suitable for drinking purposes unless it is treated with the water agencies. Thus the aim of this study is to review the research work on concentration of heavy metals in drinking water sources by respective authors in their research papers . If water from these origins (region of their respective areas) are taken for drinking purposes, the physiological effects (damages) to human health have been noted.
