Surface water organophosphorus pesticides concentration and distribution in the Langat River, Selangor, Malaysia. Exposure and Health, 8, 497-511.https://repoemc.ukm.my/handle/123456789/1502Pesticide contamination in the environment is a contemporary global issue. As agricultural production through crop planting in Malaysia now supports both energy and food productions, the concentration and distribution of pesticides in surface water may have changed. Therefore, this study assesses the concentration and distribution of organophosphorus pesticides (quinalphos, diazinon and chlorpyrifos) contamination in the Langat River, Selangor.enOrganophosphorus pesticidesContaminationSurface waterSolid-phase extractionHPLC DADLangat River BasinJournal
