A study has been over at first glance deposit types of ten channels over the Feni Lake estuary have been examined so you’re able to character the fresh accumulation, supply and you will pollution amounts of heavy metals. The outcomes indicated that the average material (?g g-1) off seven chosen big metals accompanied the transaction from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (step one.09) > Due to the fact (0.85) > Hg (0.71), and the density varied spatially and you will seasonally with apparently high profile on upward station and you will for the wet 12 months. Tolerance feeling amount (TEC) and you can likely perception attention (PEC) values indicated that the fresh concentration of just Ni and you may Cr was basically probably sometimes exhibit side effects towards ecosystem. Enrichment factor (EF), geo-accumulation directory (Igeo) and you will contamination basis (CF) analyses indicated that Ag, Co and you can Hg were in the modest so you can higher pollution profile and you will the latest sleeps (As the, Cr, Ni, Pb and Mn) have been in the no so you’re able to reduced pollution profile. Continue reading “Predicated on deposit quality guidelines (SQGs), this new deposit products was basically greatly polluted with Ag and you will Hg, and you may modestly with Co”
