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 (1.88–2.10 ppm), Pb (2.70- 5.25 ppm) and Cr (13.30–23.78 ppm) 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.

该研究的目的是评估巴亚韦弗鸟（Ploceus philippinus）排泄物中的重金属污染。）。从存在于三个地区的巢状殖民地收集样品。Ludhiana（位置I），Ropar（位置II）和Ferozepur（位置III）分别位于旁遮普邦的中部平原区，起伏平原区和西部平原区。在干排泄物中，通过ICAP-AES检测到15种元素；由于Pb，Cd，Cr是有毒重金属，B，Fe，Cu，Ni，Zn，Mn，Mg，Ca，P，S，Na是必不可少的元素。有毒重金属，即。从研究地点收集的排泄物中，铅（1.88-2.10 ppm），铅（2.70-5.25 ppm）和铬（13.30-23.78 ppm）高于正常范围。统计分析表明，重金属和位置之间存在显着差异，这表明由于研究地点不同类型的污染，Baya Weaver Bird粪便中不同位置的不同金属的生物蓄积性。
