Depuration of heavy metals Pb and Cd content in blood cockles (Anadara antiquata) with different filters
2021
Overview
The presence of heavy metals in the waters has a negative effect on the growth, reproduction, and survival of aquatic biota. Lead (Pb) is a toxic material that easily accumulates in human organs and can cause health problems in the form of anemia, impaired kidney function, disorders of the nervous system, brain and skin. The limit consumption of Pb is 0.2 - 2.0 mg per day. Cadmium (Cd) is the heavy metal most commonly found in the environment, especially the water environment, and has a high toxic effect, even at low concentrations. This study aim to determine the best filter to reduce the Pb and Cd content of blood cockle ( Anadara antiquata ). The research method is experimental using a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments test used Gracillaria sp, zeolite and activated carbon filters. The test for heavy metal content used the AAS test. The results showed that the difference of filter have an effect on the reduction of Pb and Cd content in blood cockle. Giving activated charcoal filters can decreased the Pb and Cd content higher, with an average percentage of 31.5% for Pb and 28.56% for Cd.
