Abstract

The Blanakan River Estuary, located on the northern coast of West Java, receives heavy metals from anthropogenic activities nearby. This study investigates Cu, Cd, and Zn metals in water and their accumulation in fish (commercial and non-commercial). The samples (water and fish) were collected from seven sampling stations. The metals concentration in the surface water of the Blanakan River Estuary has exceeded the limit allowed by the Indonesian government. The average metal concentration sequence in commercial and non-commercial fish was Zn > Cu > Cd. In general, it was found that the concentration of Zn and Cd (Cu) metals in fish had (had not) exceeded the limits allowed by the FAO/WHO. Based on Bioconcentration Factor (BCF) value, all of fishes species have a low ability to accumulate heavy metals (BCF <1000). Based on Estimated Daily Intake (EDI), all fish species have a low risk for health, both for adult and children.
