Distribution of Turbidity Values, Total Suspended Solids and Heavy Metals Pb, Cu in Tanah Merah Beach Waters and Semujur Island Waters, Bangka Tengah Regency

Abstract

The high activity of tin (Sn) mining in the coastal areas of Bangka waters has an impact on turbidity, suspended solids, and increased levels of heavy metals (Pb, Cu). The study was conducted from February until April 2020 aims to determine the relationship between turbidity, total suspended solids (TSS), and concentrations of Pb and Cu in the Tanah Merah beach waters (TM) and Semujur Island waters (SM) which are characterized by the presence or absence of tin mining. (Sn) as a source of pollution. The results showed that the level of turbidity in TM (0.8-3.4 mg/l) was higher than in SM (0.4-0.8 mg/l) and Total Suspended Solid values in TM (149-185 mg/l) were lower than in SM (165-202 mg/l) and between (155-175 mg/l). The concentrations of heavy metals Pb in TM (0.05-0.09 mg/l) and Cu in TM (0.01-0.02 mg/l) were lower than in SM (Pb: 0.12-0.14 mg/l) and Cu (0.04-0.1 mg/l). Turbidity levels and high TSS values can be affected by the speed and direction of ocean currents. Heavy metals Pb and Cu are thought to be bound very effectively by TSS, their distribution is strongly influenced by the direction of the current and the velocity of the current formed.
