چکیده
To explore the seasonal variability and associated health risks of dissolved trace elements (TEs), a total 45 water samples (15 in each season) were collected from Seti River Basin during pre-monsoon, monsoon, post-monsoon seasons. A 15 TEs analysed results revealed that Arsenic (As), Chromium (Cr), Nickel (Ni) primarily controlled by lithogenic sources, whereas, Cadmium (Cd), Cobalt (Co), Cesium (Cs), Cupper (Cu), Manganese (Mn), Lead (Pb), Zinc (Zn) derived both anthropic geogenic sources. Additionally, concentration Zn was markedly high, especially season nearby landfill site, indicating signatures. The hazard index cancer found to be < 1.00 10−6–10−4, respectively minimum impacts. quality 50 throughout sampling periods, with better monsoon. This study could help formulate necessary policies for sustainability Himalayan Basins.
