Abstract
The objective of the study was to assess the heavy metal contamination in excreta of the Baya Weaver Bird (Ploceus philippinus). Samples were collected from nesting colony sites present in three districts viz. Ludhiana (location I), Ropar (location II) and Ferozepur (location III) falling in Central plain zone, Undulating plain zone and Western plain zone of Punjab respectively. In dry excreta samples fifteen elements were detected through ICAP-AES; As, Pb, Cd, Cr were toxic heavy metals and B, Fe, Cu, Ni, Zn, Mn, Mg, Ca, P, S, Na were essential elements. Toxic heavy metals viz. As (1.88-2.10ppm), Pb (2.70- 5.25ppm) and Cr (13.30-23.78ppm) were found above normal range in excreta collected from studied locations. Statistical analysis showed significant difference among heavy metals and locations which signifies the bioaccumulation of different metals at different locations in excreta of Baya Weaver Bird due to different type of contaminations at studied locations.
