Contamination of Heavy Metals Al, As, Cu, Cr, Mn, Ni, Pb, Sn, Zn and Fe in Sediment from Bang-Yai River in Phuket Province

Abstract

From the concentrations of heavy metals Al, As, Cu, Cr, Mn, Ni, Pb, Sn, Zn and Fe in bottomsediment from Bang-Yai river and the catchment Bang-Yai river in Phuket Province, Al and Fe were foundin higher concentrations, the range were 28,945-99,961 and 6,427-55,568 mg/kg respectively. Sn and Pbwere found in the range of 471-15,174 mg/kg and 17-113 mg/kg respectively. These metals were stronglypolluted and found higher concentration of element from Bang-Yai river than the catchment Bang-Yai riverbut the distribution was uncritical. Mn was found in the range of 371-1,773 mg/kg. The other heavy metalswere found less concentration and unpolluted than in nature. All these heavy metals came from carriedbottom sediment of natural materials and activities from Tin mines, was deposited in the river.
