Abstract

Poor air quality in Johan Setia can be unhealthy and negatively affect sensitive groups like children and elderly. Long-term and short-term exposure towards sensitive groups could decline lung function and steer to chronic lung diseases. The aim of this research is to address the baseline of respiratory health status of pre-schoolers in relationship to the exposure to relatively concentrated air pollutant within specified duration. The study location was carried out at Johan Setia, where it surrounded by large scale industrial sectors. Collected information were later compared to the data collected from the District of Kuala Selangor where it represents the control site. The objectives of the research are to determine the correlation between preschoolers’ respiratory health and changes in the core index value of PM10 and PM2.5 in the ambience. The duration of air quality data from the year 2018, 2019 and 2020 were collected from DOE AQ Monitoring Station as the independent variable meanwhile the health status of preschoolers was used as dependent variable. Information was collected using survey instrument, with guided questionnaires. Beside health status, the survey also included parent’s knowledge, attitudes and practises (KAP) towards air quality. Data analysis for PM10 and PM2.5 in Johan Setia shown exceeding the standard annual range. While other pollutants such as ozone (O3), carbon monoxide (CO), sulphur dioxide (SO2), and nitrogen dioxide (NO2) remained within standard range. This study has revealed that there is relationship between children exposed to high PM reading with the occurrence of symptomatic respiratory health. Analysis of KAP is to be disclosed at the end of this study.
