Abstract

Green mussels or Perna viridis have the ability as filter feeder, which makes them very easy to be contaminated due to water pollution by heavy metals, such as lead (Pb) and chromium (Cr). Meanwhile, these mussels are widely consumed by public. This research was a study of depuration, which conducted to learn the heavy metals extrication from these mussels to make the consumption safer by humans. The method used is the method of water flow recirculating with a variation of duration flow (1, 2, 4, and 24 hours) as well as extraction method with a variation of concentrations of acetic acid and citric acid (5; 7,5; 10; 12.5 %), and temperature (30-80°C). Based on the result obtained, the amount of lead that can be absorbed by green mussels is larger than chromium (Cr) that is 4,402-20,701 mg/kg from 1 until 3 days of dipping, while chromium is 0.773-7,266 mg/kg. The method of water flow recirculating for 1 hour obtained the optimum result with the decrease of the levels of lead and chromium as much as 67.037 % and 54.899 %. While the optimum extraction method obtained in 10 % of acetic acid at 40°C with stirring at 120 rpm, resulted in the decrease of lead and chromium as much as 93.335 % and 81.892 %, but this treatment can also causes the decrease of protein level about 41.602 %.
