ABSTRACT
Plumbum is heavy metal that is toxic and source from paint industry, battery and printing. Tenggang river near with small industrial environment (LIK) and settlement so that increasing the waste entering to river including heavy metal waste. This is the reason for this research do. This study aims to determine the heavy metal Pb of water and Nile tilapia meat, bioconcentration factor of nile and knowing the limit of weekly consumption of nile tilapia meat (MTI). The study was conducted in April 2019. The method used was a descriptive method with the determination of sampling using purposive sampling. The result of heavy metal Pb concentration in water averaged by 0,155 mg/l. Concentration of heavy metal Pb in Nile tilapia (Oreochromis niloticus) meat averaged by 2,35 mg/kg. The calculation result of bioconcentration factor (BCF) is range between 12,03 – 17,17. The maximum limit result of weekly fish consumption is averaged by 0,63 kg/minggu. Based on the results obtained it can be concluded that concentration of heavy metal Pb in water and nile tilapia tenggang river quite high and has reached above the permisible limit. BCF number of heavy metal in nile tilapia fall into the category of low accumulative levels (BCF < 100).
