Source-specific health risk assessment of potentially toxic elements in Wular Lake sediments, Kashmir Himalaya: a Monte Carlo simulation approach coupled with an APCS-MLR receptor model.
Wular Lake, a Ramsar wetland in the Kashmir Himalaya and one of South Asia's largest freshwater lakes, is under growing anthropogenic pressure. This study assessed six potentially toxic elements (PTEs: Cr, Ni, Cu, Zn, Cd, and Pb) in 22 surface-sediment samples using contamination indices, ecological and probabilistic (...
