Health Risk Assessment of Cd, Cr and Mn in Some Vegetables Irrigated by Waste Water

Abstract

This study was carried out to assessment the hazard index and hazard quotient of Cd, Cr and Mn in chard, celery, leek and onion vegetables irrigated by waste water channel and fresh water in Erbil governorate. The results related to vegetable comparisons showed that Cr and Mn contents significantly increased in the magnitude order of chard > leek > onion > celery, while Cd concentrations increased in the order of chard > leek > celery > onion. The concentrations of Cd, Cr and Mn were present to be highest in chard in comparison to other vegetables. However the result show that the highest HI was found in chard (1.101) followed by leek (1.0808) , celery (0.8437) and onion (0.8412).
