Kandungan Logam Berat Pb Dan Cr Pada Air, Sedimen Dan Kerang Darah (Anadara Granosa) Di Perairan Panipahan Kecamatan Pasir Limau Kapas Kabupaten Rokan Hilir
Heavy metals in the water might be accumulated in the sediments as well
in the benthic organisms such as clam. To understand the Pb and Cr content, a
research has been conducted in May 2019. The water, sediment and clam samples
were taken from 3 sampling sites, in the area close to mangrove (S1), around the
shipyard and settlement area (S2) and around the port and settlement area (S3).
Samplings were conducted 3 times, once / 2 days. Results showed that Pb and Cr
content in water was 0.029 mg/L and 0.007 mg/L, in the sediment was 0.535
mg/kg and 0.204 mg/kg and clam was 0.114 mg/kg and 0.020 mg/kg respectively.
The water in all sampling sites can be categorized as polluted, but the heavy metal
concentration in the clam obtained from the sampling areas were lower than the
safety standard issued by the Indonesian Government, and it might be consumed
safely.
