HEAVY METALS CONTENTS IN WATER AND SEDIMENT IN KWANYAR AND SOCAH WATER, BANGKALAN

Heavy metals are very dangerous for marine life as well as the trophic level above. This study aims to determine the content of heavy metals in the waters Socah and Kwanyar Bangkalan. This study was conducted over 3 months. Water sampled using a sample bottle, while sediment samples was taken using a grab sampler. The sample was then analyzed by atomic absorption spectrophotometer (AAS). Results showed that the content of heavy metals Cd, Cu, Pb and Hg in the water in the Socah and Kwanyar waters still below the seawater quality standard limits, whereas the heavy metal content in sediments exceeded the water quality standard for marine sea. In general, the content of heavy metals in sediment is higher than on the water.
