Abstract

Introduction: Malaysia is one of the countries that put huge efforts in strengthening their paddy and rice industry due to its vital significance as country's staple food. Hence, in an effort to improve production yield, the use of pesticides consequently prevalent and act as a crucial tool. However, pesticides contamination has become unavoidable problems especially among paddy farmers who are constantly handling pesticides as it gives variety of adverse health symptoms. Objective: To determine the concentrations of pesticides (azoxystrobin, pymetrozine and tebuconazole) in the personal air samples and their reported health symptoms among paddy farmers and non-exposed group. Methodology: A comparative cross-sectional study was conducted among 85 paddy farmers and 85 non-exposed group in Kampung Sawah Sempadan, Tanjung Karang, Selangor by convenient sampling. All respondents were required to answer a set of questionnaires. A solid sorbent tube (XAD-2 resin) with a clip was attached to the respondents' breathing zone and an air pump fastened to the belt to collect the personal air samples. Pesticides collected in the XAD-2 resin were extracted with acetone, centrifuged, concentrated via nitrogen blowdown and reconstituted with 1mL of 3: 1 ultrapure water: methanol solution. The extract was analysed by using Ultra-high-performance chromatography tandem mass spectrometry (UHPLC-MS/MS). Results and Discussion: The maximum concentrations of azoxystrobin, pymetrozine and tebuconazole found in personal air samples were 53.80ng m-3, 365.80ng m-3 and 337.l0ng m-3) respectively. The concentrations of target compounds were significantly different among paddy farmers and non-exposed group There was significant difference on reported health symptoms such as breathing difficulties, chest pain, nausea, vomiting and runny nose among paddy farmers and non-exposed group. Other than that, there was significant association between sociodemographic background (age and level of education) and reported health symptoms among paddy farmers as compared to non-exposed group. There was significant association between lifestyle ( smoking status, consumption of vegetables and fruits once a week and exercise practice) and reported health symptoms among paddy farmers as compared to non-exposed group. There was significant association between concentration of pymetrozine and tebuconazole with reported health symptoms among paddy farmers as compared to non-exposed group Conclusion: The findings in this study can be beneficial in terms of risk management within agricultural community. Keywords: Pesticides, inhalation, reported health symptoms, personal air samples, paddy farmers
