Feces of captive wild mammals were collected from Udaipur zoological garden, Rajasthan to establish the level of heavy metals in atmosphere. Feces were treated with concentrated nitric acid and perchloric acid before analysis using atomic absorption spectrophotometer (AAS). The mean concentration value were found in range of lead (Pb) 3.9 to 16.70, cadmium (Cd) 0.43 to 4.43, Chromium (Cr) 0.55 to 6.19, Copper (Cu) 8.41 to 41.0, and Zinc (Zn) 10.1 to 40.15 μg/g (ppm). Analysis of feed and water along with the soil in cages which is receiving particulate air pollutants indicates that air pollution is the primary cause due to high density of traffic in the area.
