Publication Description :
to the rapid urbanization and industrialization. The present research was conducted to assess the ecological and health risk of heavy metals (Cr, Ni, Cu, As, Cd and Pb) from agricultural soils in the industrial areas of Tangail district, Bangladesh. Heavy metals were investigated utilizing an Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The mean concentrations of Cr, Ni, Cu, As, Cd and Pb in different soil sampling sites were found 6.73, 29.74, 24.69, 4.79, 2.50 and 19.90 mg/kg, respectively. The mean concentration of the studied heavy metals were found underneath as far as possible set by the Dutch standard, Canadian guidelines and Australian guidelines with the exception of Cd. Principal Component Analysis (PCA) demonstrates that the vast majority of the metals in agricultural soil may originate from the anthropogenic sources. The geo-accumulation index, contamination factor and toxic unit analysis were discovered low contamination for all metal with the exception of Cd. Potential ecological risk (PER) of soils from all sampling sites showed low to very high risk. Add up to Total Target Hazard Quotients (TTHQ) for every single concentrated metal in all-out testing sites were <1 and cancer risk values were under 10-6 demonstrating low noncancer- causing and cancer risk in grown-up and youngsters for a few exposure pathways.
