Abstract
Quinalphos, Kinalux 25EC brand name, is popularly used in agriculture of the Mekong Delta. To figure out the residue concentration and bio-concentration ability of quinalphos in rice fish system in Co Do District, Can Tho City, Kinalux 25EC was applied twice in rice fish field with the producer recommended dose which was 170 mL/1000m2. Samples were collected at the day 1, 3, 7 and 14 after application, then, samples were continuously collected every 14 days to the end of experiment. Water samples were also collected after 30 minutes of applications. Residues of quinalphos were analysed by gas chromatography – electron capture detector system (GC-ECD). The results showed that quinalphos residues in fish tissue were much higher than in water. The half-life varied between one and two days fish tissue and around one day for water.
