Environmental Study on Measurement of Heavy Metal Concentrations in Tigris River at Taji Beach Area

Abstract

The present investigation was carried out on the water of the Tigris River in the Taji region, north of Baghdad, as part of the Karkh Water Project. The station was selected for a project to purify water and provide the Karkh regions with this resource. The study involved determining the levels of heavy metals in the Tigris River's waters between October 2022 and March 2023. Five heavy metals (Hg, Ni, Cr, Pb, and Cd) were extracted from three river water models. The study's findings revealed elevated levels of lead and cadmium, both of which were beyond the allowable limits of the Iraqi standard. Cadmium concentrations ranged from 0.009 to 0.034 mg/L, which is more than the allowable limits in all phases of drinking water, while lead concentrations varied from 0.005 to 0.15 mg/L, which were excessive in comparison to the permitted limits.
