Monitoring of Trace Elements in Groundwater of Municipal Area at Kushtia and Jhenaidah District of Bangladesh

Abstract

Groundwater samples from the municipal residential areas of the Pearatola, Kushtia (23.897975° N and 89.123735° E) and the DPHE, Jhenaidah (23.544454° N and 89.164694° E) districts were analyzed for trace elements determination of Iron (Fe), Manganese (Mn), Lead (Pb), Cadmium (Cd) and Zinc (Zn) evaluating the health effect of these trace elements is the prime object of this investigation. Fe, Mn, Pb, Cd and Zn in groundwater water were determined by atomic absorption spectroscopy (AAS) on direct flame methods. The examined concentrations of Fe, Mn, Pb, Cd and Zn are respectively 0.740 mg/L, 0.370 mg/L, 0.040 mg/L, 0.0040 mg/L and 0.0570 mg/L (ppm) which were present in the groundwater sample of Kushtia. The absolute concentrations of Fe, Mn, Pb, Cd and Zn are respectively 0.490 mg/L, 0.220 mg/L, 0.030 mg/L, 0.0030 mg/L and 0.0310 mg/L (ppm) which were present in the groundwater sample of Jhenaidah.  Fe contamination of examined areas samples in 0.740 ppm and 0.490 ppm of cases exceeded the WHO criteria and 0.30 ppm exceeded BD standards which is a very scary risk factor for human health. The investigated data should be useful and helpful for general public awareness intake of groundwater.
