چکیده
Our aim to establish the metal (Pb, Cd, Cr, Cu and Zn) levels of Mammalian scat samples deriving from sanctuaries of western Rajasthan and comaprision between the concentrations of Talchaper Blackbuck Sanctuary, Churu and Dhavadoli Protected Area, Jodhpur. Restric tions on the sampling because of Wildlife Protection Act (1972) prevents taking of samples of living tissues to analyse body burdens of contaminants that the wildlife may be carrying, fecal samples were analysed. According to our results the concentrations of metals (μg/g (ppm) dry weight) in fecal samples were higher in the samples of Talchaper then the Dhavadoli. They were in the range of 9.86 to 24.24 (Pb), ND to 0.49 (Cd), 2.45 to 6.62 (Cr), 12.19 to 22.69 (Cu) and ND to 12.61 (Zn) in Talchaper whereas in Dhavadoli, 0.76 to 1.55 (Pb), 0.72 to 1.26 (Cd), 1.14 to 4.71 (Cr), 12.21 to 17.7 (Cu) and 4.53 to 9.61 (Zn). Vegetation, soil, salt and water of Talchaper Blackbuck Sanctuary, Rajasthan showed good concentration whereas Dhavadol i samples showed background concentrations of heavy metals (Pb, Cd, Cr, Cu & Zn). Index term:Scat, Heavy metals, Bioindicator, Wild mammals, Western Rajasthan. ————————————————————
