Abstract

Introduction: Indoor air pollution (IAP) contributes significantly to the global disease burden and is the world's second largest contributor to ill health. Most children spend more time at school rather than at homes. School environment is a crucial part to be taken care in order to supervise their safety, health and achievements in their life. Objective: This study aims to study the relationship between air quality parameters [PM10 and heavy metals (Pb, Cd, Cr, As, Ni) concentrations] in indoor air and dusts from school environment with the lung function and respiratory symptom of the school children. Methodology: This cross-sectional study involved 120 school children in the secondary school and were selected using random sampling method. A set of standardized and validated questionnaires were used to obtain data on sociodemographic background and respiratory health symptoms. Health assessment that was being carried out on children were lung function test using spirometer. Written consent forms were distributed to the respondents prior to all procedures. Data on pollutants such as particulate matters and other parameter were measured inside of the classrooms. Results and Discussion: Majority have abnormal FVC% predicted value which is 81.1%, meanwhile only 18.9% categorized as normal. For FEV1 % predicted value, only 27.0% were normal and the rest it was abnormal. FEV1/FVC % predicted showed that the result of 94.6% normal with only 5.4% abnormality. Conclusion: The findings conclude that exposure to heavy metals in indoor air and settled dust of air pollutants around the school environment did not affect the of lung function abnormality and the respiratory health symptoms reported. Only arsenic was the main predictors affecting the wheezing rate of the students. Keywords: Heavy metals, Indoor air pollution, Lung function, and Respiratory symptoms
