摘要：Feces of captive wild mammals were collected from Udaipur zoological garden, Rajasthan to establishthe level of heavy metals in atmosphere. Feces were treated with concentrated nitric acid and perchloric acid beforeanalysis using atomic absorption spectrophotometer (AAS). The mean concentration value were found in range oflead (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 receivingparticulate air pollutants indicates that air pollution is the primary cause due to high density of traffic in the area.
