HEAVY METAL CONTENT OF LEAD (PB) IN COMB PEN SHELL (ATRINA PECTINATA) IN INDUSTRIAL CITY WATERS

Comb pen shells (Atrina pectinata) are one of marine biota in industrial city waters, which are threatened by contamination of lead heavy metal (Pb) from industrial and inorganic waste. One way to see the size of the content of lead heavy metal (Pb) in comb pen shells is through the size of shells. This study aimed to determine the content of lead (Pb) in comb pen shells (Atrina pectinata) in industrial waters and to determine the correlation between the size of comb pen shells and the content of lead (Pb) in comb pen shells in industrial city waters. The observational results showed there was lead (Pb) content in comb pen shells (Atrina pectinata) in industrial city waters based on various sizes, which were large (1.147 mg/kg), medium (0.133 mg/kg), and small (0.084 mg/kg). The statistical analysis showed the calculation of lead content (Pb) in comb pen shells with various sizes had a correlation value of 0.618. Mean of lead content in comb pen shells (Atrina pectinata) based on various sizes, none of which had exceeded the quality standards that were allowed for lead heavy metal and the correlation of comb pen shells of different sizes had a strong relationship
