The Preliminary Investigation of Organophosphate Pesticide Residues on Green Mussel Perna viridis (bivalvia: Mytilidae, linnaeus, 1758) at Demak Coastal Waters Central Java Indonesia

Abstract

The organophosphate pesticides pollution in the Demak coastal waters and their impact on green mussel were estimated. The paper presents the occurrence level of organophosphate pesticides residues in marine waters and green mussel which were collected from marine coastal areas. Six selected organophosphate pesticides compounds (Chlorpyrifos, Profenofos, Diazinon, Fenitrothion, Malation and Methidathion) of contaminant have been determined in the marine water and green mussel of Demak coastal waters. The samples were then analyzed by using gas chromatography and followed by using the method of Standard Method Examination. The result showed that the average concentration of organophosphate pesticides Chlorpyrifos, Profenofos, Diazinon, Fenitrothion, Malation and Methidathion in green mussel were 0.22 µ g/L, below detected, below detected, 0.413 µ g/L, below detected, below detected, respectively. But all of organophosphate pesticides residues in marine waters were below detected. The highest concentration of organophosphate pesticide in green mussel showed on Fenitrothion (0.413 µ g/L) and than Chlorpyrifos (0.22 µ g/L). The concentration of organophosphate pesticides in these areas might contribute four paddy and red onion agriculture.
