摘要：The current study was carried out for quantitative and risk assessment of cadmium (Cd) andarsenic (As) from Talukas Ghora Bari and Mirpur Sakro. The concentration of Cd was determinedusing Atomic Absorption Spectroscopy instrument. The As concentration was measured with thehelp of the Arsenic Kit Method. For analysis of Cd, samples were prepared by the Microwavedigestion method, whereas for As analysis, water samples were analyzed directly. The range ofCd content was observed from the studied areas as 1 – 10 μg/L and 1.2 – 11.2 μg/L, respectively.The groundwater water of Talukas Ghorabari and Mirpur Sakro showed the mean Cd content of 5μg/L and 6.1 μg/L, respectively. The Cd contamination of 56% and 80% was found in Ghorabariand Mirpur Sakro, respectively. The range of As content of 0.00 – 50 μg/L and 10 – 80 μg/L wasdetermined from Ghorabari and Mirpur Sakro, respectively. Hazard Quotient for Cd > 1 wasfound in 40% of both children and infants in the groundwater of the study area, which may causenon-carcinogenic risk. About 48% of water samples declared HQ values > 1 for adults in the waterof Ghorabari. Since 84% of samples showed the HQ values > 1 for children and infants. The HQvalues of As for Adults of the Mirpur Sakro were observed in 63.3% samples, whereas forchildren and infants, HQ values were found in 100% samples. It is therefore stronglyrecommended that groundwater must be treated before consumption by the people of the areaunder study.
