Abstract

Introduction: Tanjung Karang, Selangor is widely known for its paddy cultivation activity and the third largest paddy field in Malaysia. The contamination of pesticides in agriculture field is very common as the pesticides is used to increase the paddy productivity and to reduce plant diseases. Environmental exposure of humans to agrichemicals is common and results in both acute and chronic health effects such as acute and chronic neurotoxicity. Objective: To determine the concentration of pesticides (propiconazole, difenoconazole, chlorantraniliprole) in the personal air samples collected at Tanjung Karang, Kuala Selangor paddy field and assess the potential health risk to the farmers. Methodology: A cross sectional study was conducted in Kampung Sawah Sempadan at Tanjung Karang. 83 respondents were interviewed to get the pesticide's information, personal information of respondents and their exposure information. A glass fibre filter and an XAD-2 resin tube were attached in the breathing zone with a clip, and an air pump was fastened on the belt to collect personal air samples. Pesticides trapped on the XAD-2 resin and filter were extracted with 10 mL of acetone, centrifuged, concentrated via a nitrogen blowdown and reconstituted with I mL of 3: I; ultrapure water: methanol. Aliquot (2 µL) of the extract was analysed using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Result and Discussion: The highest mean concentration was chlorantraniliprole 0.0308 ng/m3' followed by difenoconazole (0.0086 ng/m3) and propiconazole (0.0099 ng/m3). The mean Daily Inhalation Expousure (DIE) for chlorantraniliprole, difenoconazole, propiconazole were 0.49 ng/kg/day, 0.11ng/kg/day and 0.25ng/kg/day respectively. All compound did not exceed the recommended Reference Dose (RID) by United State Environmental Protection Agency (USEPA). The Hazard Quotient (HQ) for all pesticides did not exceed I and Hazard Index is also less than 1. Conclusion: There were no significant non-carcinogenic health risk for farmers during pesticides spraying due to the inhalation as the HQ and HI is less than 1. Keywords: pesticides, paddy field, air, agriculture, health risk assessment
