Abstract

Introduction: The pollutant concerned such as particulate matter (PM) and oxides of nitrogen (NO2) that are commonly known to petrochemical industries where all these are among five controlled pollutants under Malaysian Air Pollution Index (MAPI). Exposure to indoor PM10 and NO2 may increase the risk of getting respiratory illness among school children. However, there are very limited studies related to exposure to PM10 and NO2 and respiratory health among school children near to petrochemical industry area in Malaysia. Objective: The objective of this study was to study the exposure to PM10 and NO2 and respiratory health among primary school children living near petrochemical industry area at Kertih, Terengganu. Methodology: This cross sectional comparative study was conducted among a total of 120 primary school children and the entire respondents were Malay, a total of 60 school children from Sekolah Kebangsaan Paka III, Kertih were selected as a studied group and 60 school children from Sekolah Kebangsaan Serdang, Dungun were selected as a comparative group. A random sampling was used to select the respondents based on inclusive criteria such as aged between 10 to 12 years old, boys and girls and living near petrochemical industry area for studied group and living far from petrochemical industry area for comparative group. Exposure of PM10 was measured using DustTrak Aerosol Monitor while NO2 was measure using LaMotte Air Sampling Pump and all equipments were placed at the back of classroom with the same level of breathing zone during school hours. Questionnaire adapted from American Thoracic Society (ATS) was used to collect information on respondent's socio-demography background and respiratory symptoms. Lung function test was performed using Spirometer during school hours. Result and Discussion: Results showed that the mean concentration of PM10 (79 g/m3) and N02 (3.73 ppm) for studied group was higher compared to the mean concentration of PM10 (49 g/m3) and NO2 (0.14 ppm) for comparative group. Symptoms that most experienced by the respondents were cough(53.33%), followed by wheezing(26.67%), phlegm(25%), and chest tightness(13.33%). As overall, reported respiratory symptoms were significantly higher among studied group compare to comparative group. Significant reduction value of FEV1/FVC% predicted showed that there was airways obstruction for lung function among studied group compare to comparative group. Therefore, lung function test showed that there was lung function reduction for studied group compared to comparative group. Conclusion: The findings from this study indicated that the exposure to indoor PM10 and NO2 concentrations may increase risk of getting respiratory symptoms among primary school children living near petrochemical industry area. Besides that, reduction of lung function among primary school children in exposed area, may have lung function impairment due to prolong exposure of PM10 and NO2 concentrations. Keywords: PM10, NO2, Respiratory Symptoms, Lung Function, Primary School Children.
