The effectiveness of soaking duration on blood cockles (Anadara granosa) with activated charcoal towards reducing metals lead (Pb)

Blood cockle (Anadara granosa) is one of the marine biotas that can be used as a bioindicator of the pollution level of sea water. The nature of blood cockle stays in one place because of their slow movement and they are non-selective filter feeders which filter water in order to get food. The use of activated charcoal during soaking is to keep the food safety from blood cockle contaminated with heavy metals. The purpose of this study is to determine the effectivity test of soaking duration on blood cockle (Anadara granosa) and activated charcoal toward reducing metals lead (Pb). This study employed Randomized Complete Design (RCD) using three different soaking periods such as 30 minutes, 60 minutes, and 90 minutes. The samples were analyzed by Inductively Coupled Plasma Emission (ICPE). The parametric data was analyzed with One Way Anova test. The result of the study showed that the soaking duration among 30 minutes, 60 minutes, and 90 minutes in activated charcoal showed significantly different (P< 0.05) toward the levels of lead.
