Heavy Metal Contamination and Human Health Risk Associated with Sediment of Ganges River (Northwestern Bangladesh)

Ecological and public health risk assessment of potentially toxic elements in the surface sediments of the Pasur river estuary, Bangladesh

“…( Supplementary Table 5 ). The EFc of sediment ranged from 0.28 to 2.60 in the Bengal Basin river system of Bangladesh, which was greater than the current findings [ 29 ]. The EFc of the PTEs (except Cd) presented no enrichment ( EFc < 1) in all the sites during the studied seasons.…”

“…Furthermore, the pollutant load index (PLI) and potential ecological risk index (PERI) have been established to measure the combined hazard of a large number of PTEs in sediment [ 23 , 27 ]. Non-carcinogenic health risk of PTEs can also be assessed by estimated average daily doge (ADD), hazard quotient (HQ), and hazard index (HI), which together with cancer slop factor (CSF) are also used to estimate the potential cancer risk of the studied PTEs through the use of contaminated sediment [ [28] , [29] , [30] , [31] ].…”
