The contamination of filter feeder mussel Perna viridis Linnaeus, 1758 (Bivalvia: Mytilidae) by organophosphate pesticide at Brebes marine waters Central Java, Indonesia

Abstract

In the last five years, organophosphate pesticides have been introduced in red onions fields in Brebes. This will broadly impact to the ecosystem, including the filter feeder marine organisms such as green mussel P. viridis. This article presents the occurrence level of organophosphate pesticides residues in marine waters and green mussel which has collected on Brebes marine areas. Some selected organophosphate pesticides compounds (Chlorpyrifos, Profenofos, Diazinon, Fenitrothion, Malation and Methidathion) of contaminant have been determined. The samples were analyzed by using gas chromatography and followed by using the method of Standard Method Examination. The results showed that average of six residues (Chlorpyrifos, Profenofos, Diazinon, Fenitrothion, Malation and Methidathion) in marine water were undetected (<0.0004 ppm). The merely concentration of PPOs detected was Chlorpyrifos 0.31 µg/L detected in green mussel. The concentration of organophosphate pesticides in these areas might contribute by the usage of organophosphate pesticide from red onion fields
