Abstract
An edible gastropod, Filopaludina javanica, is widely distributed in freshwater habitats. It was the most abundant gastropod species with variation on size at some lakes in Bogor. However, the relation between morphological size and heavy metal concentration in F. javanica is barely understood although gastropods are well known to accumulate heavy metal. The aim of the research is to measure the impact of concentration of lead (Pb) and cadmium (Cd) concentration to the morphological size of F. javanica in Situ Gede, Bogor. Sampling of the species was carried out in February and April 2017 in Situ Gede (SG), Situ Panjang (SP), Situ Burung (SB) and Situ LSI (SL) while samples for heavy metal accumulation analysis were collected in January and February 2018 in SG. The morphological characteristics of the samples’ shell were measured. Body mass samples were powdered and analyzed using Atomic Absorption Spectrophotometry (AAS). The average range of length and wide shells (mm) were 8.89-30.25 and 7.40-24.80, respectively. The average concentration of Pb and Cd were 0.82 and 0.11 ppm, respectively. The morphometric variability of the species varied among lakes while the concentration of Pb and Cd in this study was generally lower than the acceptable limit.
