Assessment of lead contamination on aquatic habitat and street snacks in makassar coastal area, indonesia

Abstract

Lead can be a poison to the environment which may affects all body systems. Lead can also affect human health especially those who frequently exposed. Lead potentially lowering level of intelligence, growth, loss, causing anemia, and disorder among children as lead is neurotoxin and accumulative. In addition, lead can cause a decrease in the ability of the brain, whereas in adults may cause interference of high blood pressure and other tissue toxicity. Any increase in the levels of lead in the blood of 10 ug/dl led to a decrease in IQ of 2.5 points or 0.975 IQ. The research aims to assess the potential health risk among people who exposed to lead in the coastal area of city of Makassar. We investigate the distribution of toxic lead in Makassar coastal area namely; sea water, sediments, shells and crab. Then investigate lead toxins around coastal such as lead in soil, dust, snacks and air. After create distribution maps lead risks we create analysis of environmental and health risks assessment. Result revealed that the analysis of spatial distribution of Lead in the sediment shows that the high distribution was in station 3 in Mariso districts then coastal Tallo area and the lowest was in Tamalate District. While the analysis of the spatial Pb distribution in mussels seen that the highest distribution Pb was in station 4 of districts Mariso then coastal waters Tallo area and the lowest was in Tamalate District 5.00 to 7.20 mg/g. In conclusion, it revealed the concentration of Lead at all stations of those four districts have exceeded the level of allowed standard and may potentially lead to a hazard both to environment and human being who are living in the surround area.
