Abstract

Introduction: Tanjung Karang, Kuala Selangor is the third largest paddy field in Malaysia. The pesticide can produce a positive impact on destroying pest that can destroy agricultural activities but it also gives a negative impact on other organisms that act as a biological control and not to mention it exerts health risks on the farmers themselves. Objective: To determine the concentration of pesticides in paddy soil samples and their associated dermal health risk among farmers at Kampung Sawah Sempadan, Tanjung Karang, Kuala Selangor. Methodology: The study was conducted at Kampung Sawah Sempadan in Tanjung Karang. 24 soil samples were collected from 24 paddy blocks that consist of Block A to X. Soil sample was extracted using of acetonitrile (ACN): ultrapure water (1: 1) and the aliquot of the extract was injected into ultra high performance liquid chromatography - tandem mass spectrometry (UHPLC-MS/MS). 155 farmers were interviewed using a set of questionnaire to obtain the information such as pesticides exposure, usage of personal protective equipment (PPE) and personal hygiene for dermal health risk assessment. Result and Discussion: The Hazard Quotient (HQ) and Hazard Index (HI) for all compounds were less than 1 indicating that the risk of pesticides to the farmers was not significant. The lifetime cancer risk (LCR) for pymetrozine was at a clearly acceptable risk level (LCR <1 o·6) in the range of 2.03 x 10-14 to 8.67 x 10-14_ Conclusion: There was no significant non-carcinogenic and carcinogenic health risk for farmers work in paddy soil for the exposure of 27 years. Keywords: Pesticides contamination, paddy soil, agriculture, UHPLC-MS/MS, health risk assessment
