Abstract

The current study was designed to determine the concentrations of toxic metals (Ni, Pb and Cr) in feathers of birds collected from four regions of NE Pakistan. Feather samples of birds (House Crow, Common Myna and House Sparrow) were collected from different areas. Atomic absorption spectrophotometer was used to determine the concentration of metals in feathers. Analysis of the data revealed that concentrations of Pb and Cr were significantly different (p < 0.05) among bird species, whereas no difference (p > 0.05) was detected among bird species (house crow, common myna and house sparrow) for Ni. A significant difference was found for the concentration of Pb and Ni in all the four studied regions. Whereas, non-significant difference was found in all the studied regions for the concentrating of Cr. It was revealed that there is significant rising concentration of metals (Pb, Cr) in feathers of birds in Azad Kashmir.

摘要

本研究旨在测定来自巴基斯坦东北部四个地区的鸟类羽毛中有毒金属(镍、铅和铬)的浓度。从不同地区采集了鸟类(家鸦、普通八哥和家麻雀)的羽毛样本。使用原子吸收分光光度计测定了羽毛中金属的浓度。数据分析显示,不同鸟类物种之间的 Pb 和 Cr 浓度存在显著差异(p<0.05),而 Ni 浓度在鸟类物种(家鸦、普通八哥和家麻雀)之间没有差异(p>0.05)。在所有四个研究地区,Pb 和 Ni 的浓度都有显著差异。而在所有研究地区,Cr 的浓度都没有显著差异。结果表明,在阿扎德克什米尔,鸟类羽毛中的金属(铅、铬)浓度显著升高。
