Heavy Metal Exposure and Toxicity

The aim of the study was to estimate concentrations of heavy metals in animal hair in an urban setting of the Altai Republic. Methods. The method of atomic absorption spectral analysis was used to determine the content of trace elements (Cd, Pb, Cu, Cr, Mn) in the hair of the outdoor dogs (Canis lupus familiaris) of Gorno-Altaisk. Results. The mean values for the concentration of trace elements in the hair samples of the examined dogs were the following: Cd - 0.13 pg/kg; Pb - 1.23 pg/kg; Cr - 4.0 pg/kg; Cu - 7.8 pg/ kg; Mn - 12.36 pg/kg. Concentrations of trace elements in animal hair was not associated with age, sex and area of residence of the animals. In general, the range of concentrations of the studied elements were comparable with the findings from other settings. A possible source of microelements in animal hair in Gorno-Altaisk is micro-fine solids of emissions from solid fuel heating systems and combustion engines exhaust. Conclusion: rancentrations of heavy metals in animal hair in the study setting is comparable with other settings and seems to reflect the peculiarities of the processes of accumulation of exo-toxicants and self-cleaning of the city air basin.
