Abstract
The purpose of this study is to compare Cd level in sediments and Corbula faba Hinds on distance from the mouth estuary to the sea and to correlate between Cd level in sediment and C. faba Hinds. The technique sampling was Purposive Sampling by measuring the salinity of water in the estuary which indicated that C. faba Hinds could live in the area and sampling was determined at 5 plots with 3 replications. Data analysis used the One Way Anova and Pearson Corelation tests. The results are Cd levels in sediments at the meeting point of river water with low tide seawater have the highest average of 2.16 mg/kg which is significantly different from Cd levels in sediments upstream as far as 490 m and downstream as far as 160 m . The Cd content in C. faba Hinds at the first coordinate point (7°3341.82 "S & 112°5253.11" E) to (7°3411.62 "S & 112°5314.87" E) is not different. The correlation of Cd metal levels in sediments with Cd metal in C. faba Hinds was no relationship and the mean Cd levels in C. Faba Hinds have 2.05 mg/kg exceeding the threshold for consumption feasibility based on BPOM 2017.
