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