Recently development of human lifestyle and urbanization have resulted in elevated levels of different contaminants in our environment. Heavy metals specially lead (Pb) is a main issue worldwide, regional and local level impacts the functional of an organism. In current study, House Sparrow (Passer domesticus) investigated for Pb concentrations, using liver and feathers from two areas. Samples were caught, prepared and digested and the contents of Pb was analyzed. The mean of Pb concentration in female feathers and liver was significantly different than that found in male feathers and livers from Shokat site. In addition, the average of Pb concentration of birds in Shokat site were significantly higher than those of reference site in both liver and feathers. Based on the results, it could be concluded that House Sparrow have a great capability to apply as a bioindicator species in future monitoring studies.
