A survey has been over on top deposit examples of ten stations across the Feni Lake estuary have been reviewed to help you reputation the brand new accumulation, supplies and contaminants amounts of big gold and silver coins. The outcome revealed that the typical content (?g grams-1) of seven chose heavy metals followed your order from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (step one.09) > Given that (0.85) > Hg (0.71), and concentrations varied spatially and you may seasonally having seemingly highest account within up stations and you may in the wet seasons. Endurance impact amount (TEC) and you can probable impression amount (PEC) thinking revealed that the new intensity of simply Ni and you may Cr was basically gonna sporadically exhibit unwanted effects to the ecosystem. Enrichment grounds (EF), geo-accumulation directory (Igeo) and you may contaminants factor (CF) analyses showed that Ag, Co and you will Hg had been from the average so you’re able to higher toxic contamination membership and you may the fresh new sleeps (While the, Cr, Ni, Pb and you may Mn) was basically at no to help you lowest pollution account. Possible ecological exposure list (PERI) in addition to revealed that Ag, Co and you will Hg were one particular prospective environmental chance foundation are determined within this analyzed area.
