ENVIRONMENTAL QUALITY ANALYSIS IN KENDARI BAY IN TERMS OF HEAVY METAL POLLUTANTS : Pb, Cu and Zn

Abstract

Heavy metal is one of the most pollutant loads that endangers the aquatic environment. Not only damaging the aquatic ecosystem, the presence of heavy metals also endangers the human health. This Research aims to determine the levels of heavy metals, especially Pb, Cu and Zn in water and also the sediments inside Kendari Bay waters. To determine the environmental quality of Kendari Bay waters standards, Sampling was carried out at 10 stations and sample analysis was carried out using the AAS method. Data analysis was performed using descriptive methods. The results showed that heavy metals Pb, Cu and Zn in water ranged <0.002 - 0.012 mg / L, for metals ranging from <0.002 - 0.003 mg / L, Cu metals ranged from <0.002 - 0.012 mg / L and Zn metals ranged from <0.002 - 0.003 mg / L, while heavy metals Pb, Cu and Zn in sediments range <0.002 - 0.047 mg / kg, for Pb metals range from 0.052 to 0.047 mg / kg, Cu metals range <0.002 - 0.042 mg / kg and Zn metals range from 0 , 0019 - 0.011 mg / kg. The heavy metal content of Pb, Cu, and Zn in both water and sediment samples has not exceeded the quality standards based on the Decree of the Minister of Environment No.51 of 2004 and USEPA.
