Determination of heavy metals levels in water of River Jhelum in the State of Azad Jammu and Kashmir, Pakistan

摘要

Rivers are dynamic fresh water systems that are essential for the extension of life. The goal of present research was to analyze spatial distribution of some selected heavy metals in water of River Jhelum flowing through Azad Jammu and Kashmir (AJ&K). Overall eleven water samples were collected during month of June 2014 and were examined for heavy metals lead, arsenic, chromium, cadmium, mercury, nickel, copper and zinc. The obtained results were matched with the guiding principle laid by World Health Organization (WHO) for river water. The concentration of metals namely lead, arsenic, chromium, cadmium, mercury and nickel were found beyond the permissible limits suggested by WHO. Only copper and zinc were recorded within the range.
