Abstract

Introduction: The implementation of biomass fuels in palm oil boilers produced pollutants into the air such as particulate matters (PM). PM has been related to cause many respiratory health symptoms to human, especially children. Children were vulnerable as their air intake is larger per kilogram body if compared to an adult. Objective: To determine the association on exposure to PM10 and PM2.5 with respiratory health symptoms and lung function status among children that lived in 5 kilometres radius from palm oil activity. Methodology: A cross sectional study was carried out among primary school children in Hulu Langat and Semenyih, Selangor. 86 children were selected as comparative group with the aged between 9-11 years old randomly from two primary schools in Hutu Langat while 50 children from two primary schools in Semenyih as studied group. A validated questionnaire from American Thoracic Society (ATS-DLD-78-C) was used to determine respondents' background, previous past illness and respiratory symptoms. Evaluation of PM10 and PM2.5 were done in schools and houses of the respondents by using TSI DustTrak DRX Aerosol Monitor Model 8534 and Escort LC Personal Sampling Pump. A Chestgraph HI-101 Spirometer was used to obtain lung function status among children. Results: Statistical analysis showed significant differences between exposure to PM10 and PM2.s at studied and comparative school at p<0.05. Studied group recorded higher PM10 and PM2.5 than in comparative area. Significant differences were also showed between the exposure of PM10 and PM2.5 in houses for studied and comparative group. Houses in studied area recorded higher concentrations of PM10 and PM2.5 than in comparative area. FVC (litre), FEV1 (litre), FEV1/FVC (litre), PVC%, FEV1% and FEV 1/FVC% predicted values were significantly lower among the studied group than in the comparative group. The risk of developing lung function abnormalities increased due to the exposure to PM10 and PM2.5 among the studied group (OR=3.58; 95% CI 1.964-7.546), (OR 7.14; 95% CI 3.246-15.698) and (OR 6.30; 95% CI 2.713- 14.602). The exposure to PM10 were associated with wheezing and chest tightness in the studied group (OR=26.00; 95% CI=3.032-222.928), (OR=9.00; 95% CI=2.048- 39.545) and the exposure to PM2.5 was associated with wheezing in the studied group (OR=4.68; 95% CI=l.258-17.417). FVC status had significant relationships with the concentrations of PM10 (PR 1.020; 95% CI= 1.002-1.038) and FEV 1 among studied children after controlling the confounder in this study (PR=1.020; 95% CI= 1.002- 1.038). Conclusion: The study concluded that the exposures to high concentrations of PM10 and PM2.5 increase the risk of developing lung function abnormalities and respiratory illness among the respondents. Keywords: PM10, PM2.5, lung function, children, respiratory illness
