Predicated on sediment high quality guidelines (SQGs), the fresh deposit examples were greatly polluted having Ag and Hg, and you may sparingly having Co
A survey could have been over on top sediment examples of ten programs along the Feni River estuary was assessed to reputation the latest buildup, present and you will toxic contamination amounts of hefty gold and silver coins. The outcome showed that the typical content material (?g grams-1) away from seven chose hefty gold and silver coins used the order away from Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (1.09) > Since (0.85) > Hg (0.71), therefore the concentrations varied spatially and you can seasonally which have apparently high membership at the upward station and inside the wet season. Threshold feeling amount (TEC) and you will possible feeling concentration (PEC) philosophy revealed that new intensity of only Ni and you may Cr was going to periodically exhibit side effects for the environment. Enrichment grounds (EF), geo-accumulation list (Igeo) and you will contamination factor (CF) analyses indicated that Ag, Co and you can Hg was on average to help you highest toxic contamination levels and new sleeps (While the, Cr, Ni, Pb and you can Mn) have been at zero to help you reasonable contaminants profile.
