Analysis of heavy metals content (Pb, Hg and Cd) of Batissa violacea Lamarck in the coastal waters of Calang

The objective of the study was to determine the content of heavy metals (Pb, Hg and Cd) of Batissa violacea Lamarck in the coastal waters of Calang. The research was conducted in Krueng Sabee and Panga on February 2014. Samples were collected from three stations. Samples were analyzed using AAS at Laboratory of BARISTAND. It was obtained that the heavy metals (Pb and Cd) content in B. violacea Lamarck at three stations were above the threshold value for food according to SNI No 7387 year 2009. For the mercury (Hg), it was still under the threshold at all stations. The lead (Pb), mercury (Hg) and cadmiun (Cd) content at station 1 were 6,93; 0,71; 2,54 mg/kg, respectively. Further, at station 2, they were 5,33; 0,49; 2,33 mg/kg, respectively and at station 3, they were 5,07; 0,49; 1,8 mg/kg, respectively.
