Metal determination in human tissues is the most common application of biological monitoring for screening, diagnosis and assessment of metal exposures and their risks. Humans and other living organisms are exposed to a variety of chemical pollutants that are released into the environment as a consequence of anthropogenic activities. Environmental pollutants are incorporated into the organism by different routes and can then be stored and distributed in different tissues, which leads to an internal concentration that can induce different alterations, adverse effects and/or diseases. Control measures should be taken to avoid these effects and human biomonitoring is very useful tool that can contribute to this aim. This paper deals with the quantitative determination of Fe, Pb, Ni, and Zn concentrations in fingernails of male subjects from various locations i.e., from industrial, commercial, urban, and rural areas. The levels of these metals were assayed by AAS. Studied metal concentrations in fingernails were in the order Fe > Zn ≥ Ni > Pb. This study proved that human fingernails could be used as a biological indicator for the assessment of heavy metal pollution.
