Impact of heavy metals from electronic waste on bird species concerning biodiversity: A case study in Bellandur lake, Bengaluru, India

Background: Heavy metals are one of the global environmental challenges from informal disposal electronic waste, especially after post-COVID phase. In present study, concentration three heavy (Pb, Cd, and Cr) in feathers Corvus splendens, Passer domesticus roosting sites at Bellandur Lake, Bengaluru, India were analyzed. Methods: A total nine sediment samples (0-15 cm) collected stored polyethylene bags, C. splendens P. bird shedding through molting phenomenon naturally to avoid stimuli that can create conflict for bird. The early morning 5.00 a.m. 9 To determine sediments, digested subjected AAS inductively coupled plasma-mass spectroscopy (ICP-MS). Furthermore, generalized linear model was analyzed test covariance structure diversity. Results: Pearson’s correlation is found be significant (P<0.05) contaminated sediments Analysis variance difference within bird’s species not statistically (P<0.05). Conclusion: associated with blood vessels deposited food chain, which metals. Splendens more Cr, Pb, Cd compared species.
