Considering sediment top quality guidance (SQGs), the brand new sediment trials had been greatly contaminated which have Ag and you will Hg, and sparingly with Co
A study could have been over on the surface deposit types of ten stations over the Feni Lake estuary was basically analyzed so you can profile the latest accumulation, provide and you can contamination amounts of heavier precious metals. The outcome showed that the typical information (?g g-1) of eight picked heavier gold and silver coins used the order out-of Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (step one.09) > Since (0.85) > Hg (0.71), while the concentrations ranged spatially and you will seasonally that have apparently large levels at upward stations and within the rainy seasons. Threshold perception attention (TEC) and you can possible impact concentration (PEC) beliefs indicated that the new concentration of simply Ni and Cr was in fact probably periodically exhibit side effects toward environment.
