Abstract
Introduction: Tanjung Karang is well known for its rice cultivation activities and is the third largest paddy field in Malaysia. The use of pesticides in rice cultivation activities to reduce yield loss and to maintain the quality of crop yield is inevitable and this has turned into a worry as pesticides can cause undesirable effects to human health and to the environment. Paddy farmers are routinely exposed to high levels of pesticides and this makes them at a very high risk of occupational diseases. Objective: This study aims to determine the concentration of pesticides (isoprothiolane, propiconazole and pretilachlor) in paddy water and to assess the potential health risk among paddy farmers in Tanjung Karang, Selangor. Methodology: Selected pesticides in the water samples were extracted by using solid-phase extraction (SPE) method and analysed by using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). A total of 152 questionnaires were distributed among paddy farmers to obtain information such as demographic and pesticides exposure of paddy farmers. The hazard quotient (HQ) value was calculated to estimate the potential dermal health risk of paddy farmers due to occupational exposures in paddy water. Results and Discussion: The results revealed that isoprothiolane (51.542 µg/L) was the highest mean concentration in paddy water followed by propiconazole (12.434 µg/L) and pretilachlor (0.109 µg/L). There was no significant relationship between pesticides concentrations with in situ water quality parameters. There was no significant non-carcinogenic dermal health risk due to exposure of propiconazole in paddy water as HQ did not exceed the value of one. Conclusion: Although calculated HQ showed there was no significant non-carcinogenic dermal health risk, there are concerns towards the danger of long-term exposure to the mixture of pesticides which was not assessed in this study. Keywords: pesticides contamination, paddy water, hazard quotient (HQ), ultra performance liquid chromatography tandem mass spectrometry (UPLCMS/MS), solid-phase extraction (SPE)
