Study of certain heavy metals with potential human health effects

Abstract

Abstract Heavy metals influence the human body directly or indirectly. Some of these heavy metals including Cu, Co, Mn, and Zn have functional roles that are important for the body’s various physiological and biochemical activities. But, several of these heavy metals, at high-dose, could be dangerous to the body. While, others like Cd, Pb, and Cr in minute amounts have harmful effects in the body that cause acute and chronic toxicity in humans. Unmonitored drainage processes in Iraqi rivers have been identified as this river is considered to be the main source of drinking water in Al-Abasia City; hence, the present study aims to detect levels of some heavy metals in the Al-Abasia River. The current study indicates that the highest concentrations of the heavy metals were recorded during winter, while the lowest values were reported during summer, except Pb, Fe, and Co. All heavy metals exceeded Iraqi freshwater content limits, excluding Cu, and Fe.
