Abstract
The research about analysis of the content of heavy metal lead (Pb) in sediment, sea water and blood cockle Anadara granosa L. from the caostal water of Makassar has been done. This research was aimed to figure out the Pb content in the sediment, the sea water and the blood cockle A. granosa L. The sample was taken by using Purposive sampling method. The samples preparation used composite method and Pb level in samples was determined by Atomic Absorption Spectrofotometric (AAS). The result showed that at Tanjung Bunga, the average of Pb content in the: sea water 0,289 ppm, sediment 0,609 ppm and blood cockle A. granosa L. 0,704 ppm. In the Mangara Bombang, the average of Pb content in the sea water 0,273 ppm but Pb level in the sediment and in the blood cockle A. granosa L. were not detected.
