KANDUNGAN LOGAM BERAT Pb PADA AIR LAUT, SEDIMEN DAN DAGING KERANG LORJUK (Solen sp.) DI PANTAI MADURA

Abstract

The accumulation of the heavy metal lead (Pb) into the shells can be through the food network or contact with the environment. This study aims to determine the content of heavy metal Pb in water, sediment and Bamboo Scallops meat (Solen sp.). This research was conducted in March-May 2019 on the beaches of Kwanyar Bangkalan and Talang Siring Pamekasan, Madura. The content of heavy metal Pb in water, sediment and Bamboo Scallops (Solen sp.) Samples was analyzed using the Atomic Absorption Spectro-photometer (AAS) method. In the aquatic environment, water quality measurements are carried out including salinity, temperature, pH and current. The results showed that the concentration of heavy metal Pb in the water at Kwanyar Beach was not measured, and at Talang Siring Beach was 0.13 ml / l in March, 0.10 mg / l in April and not measured in May. The Pb content in sediment at Kwanyar Beach in March was 51.04 mg / kg, April 6.11 mg / kg and 9.78 mg / kg in May, and at Talang Siring Beach in March was 72.05 mg / kg, April 3.73 mg / kg and May 2.50 mg / kg. Pb content in Bamboo Scallops meat was not measured at both beaches during the observation. The results showed that the heavy metal Pb in Bamboo Scallops meat was still below the quality standard and safe for consumption.
