Considering sediment high quality direction (SQGs), the new sediment samples was basically greatly contaminated that have Ag and you will Hg, and you will moderately having Co

A survey might have been done at first glance sediment types of 10 programs over the Feni River estuary was basically reviewed so you can character the brand new buildup, sources and you can contamination quantities of big metals. The outcomes showed that the average information (?g grams-1) of 7 chose hefty metals observed the order away from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (1.09) > Because (0.85) > Hg (0.71), therefore the concentrations varied spatially and you will seasonally having seemingly higher membership at the upward channels and you may in the rainy 12 months. Tolerance effect focus (TEC) and possible effect amount (PEC) philosophy showed that the fresh concentration of simply Ni and Cr was indeed planning occasionally showcase side effects with the ecosystem. Enrichment factor (EF), geo-buildup index (Igeo) and pollution grounds (CF) analyses indicated that Ag, Co and you will Hg was in fact on moderate in order to higher pollution membership and you may the new sleeps (Just like the, Cr, Ni, Pb and Mn) was indeed during the no so you’re able to reasonable contaminants membership. Prospective environmental risk list (PERI) and indicated that Ag, Co and Hg was the absolute most possible environment chance foundation are calculated inside analyzed town. Correlation matrix and multivariate dominating component research and you can cluster analysis advise that Ag, Co, Ni and you may Hg originated from anthropogenic present (agrochemicals, gold nanoparticles anti-microbial broker, silver plating), while Because the, Cr, Pb and you may Mn primarily originated natural geological background.
