  • 摘要:Increasing industrial activities in Lamongan District is assumed to be followed by the increase on the amount of liters in rivers and ponds. Freshwater snails (Filopaludina javanika v.d Busch 1844) that live in rivers and ponds are always exposed to heavy metals. Based on the result of the measurement of Pb in freshwater snails in Waung river, Glagah subdistrict, Lamongan, the highest amount of Pb reached 4.48 mg/kg. This aim of this research was to decrease the amount of Pb in freshwater snails. This research employed an experimental method using complete randomized design with 4 treatments and 3 repetitions; P1 (6-hour flushing procedure), P2 (12-hour flushing procedure), P3 (18-hour flushing procedure), and P4 (24-hour flushing procedure) with the reduction on the level of Pb in the “whole organ” of the freshwater snails. The results show that 24-hour of flushing has reduced the amount of Pb as much as 53.2%, from 2.65 ppm, leaving only 1.24 ppm. Meanwhile, the least reduction was found in the 6-hour flushing procedure at 7.2%. The results of the treatments have obtained amount of Pb under the minimum safety requirement set by BPOM (2009), Fisheries (DKP) No: Kep 17/Men/2004, SK Ditjen POM No. 03725/B/SK/VII/1989, in which it is stated that materials that contain heavy metals less than 1.5 ppm are safe to consume for duck weft and for human. Further researchers are suggested to investigate the accumulation of lead (Pb) in ducks that consume freshwater snails within certain period of time.
