Abstract
The study was conducted in order to evaluate contamination of sheep's wool and cow's hair with heavy metals around the vicinity of specialized industrial park of zinc (VSIPZ). Sampling of wool and hair to the number of 10 samples per tissue from each of four geographical directions were done. Control area to compare the current situation was also considered. In this experiment, the dry ash method was used to digest organic matter. To measure trace element copper (Cu) and zinc (Zn) from atomic absorption spectrometry and lead (Pb) and cadmium (Cd) from graphite furnaces was used. The results showed that there is no significant difference in the accumulation of Cu and Zn in the sheep's wool and cow's hair, but the accumulation of Pb and Cd in sheep's wool was significantly more than the cow's hair. The concentration of Zn, Pb and Cd in the sheep's wool had significant between groups. Concentrations of Cu, Zn, Pb and Cd in the cow's hair was significant in different geographical directions . Orthogonal comparisons showed that the accumulation of trace elements Zn, Pb and Cd in sheep's wool samples from VSIPZ in comparison with the control group was significantly higher; the highest concentration of these elements was shown in the South of VSIPZ. Generally, the activity of VSIPZ leads to the accumulation of trace elements of Pb and Cd in wool and hair samples from the southern and Western areas of VSIPZ that should be considered by authorities.
