Effect of Ambient Particulate Matter 2.5 Micrometer (PM2.5) to Prevalence of Impaired Lung Function and Asthma in Tangerang and Makassar
Abstract: Particulate matter
2.5 micrometer (PM2.5) emission increased with increasing number of urban
population as a result of increasing number of motor vehicles for their daily
transportation. This study aimed to determine the level of impaired lung
function and asthma and its relation to ambient levels of PM2.5 among migrant
communities in Tangerang and Makassar and socioeconomic conditions. A
cross-sectional design was implemented by involving 4,250 and 2,900 respondents
in Tangerang and Makassar respectively on April to September 2010. Cluster
sampling approach was applied. PM2.5 ambient measurements in each city were
based on the coordinates of 40 global positioning system locations. The PM2.5
levels found higher in the morning than afternoon in both cities, with average
about six folds of WHO guideline of 35 mg/m3. Asthma prevalence was found similar
in both cities (1.3%) and impaired lung function prevalence in Makassar was
higher (24%) than Tangerang (21%). Data showed there was no association between
PM2.5 levels to the prevalence of asthma and impaired lung function in both
cities. The study confirmed that exposure to PM2.5 is associated with
prevalence of asthma and impaired lung function and provided evidence showed
that the effect of air pollution was modified by certain living environment
characteristics. These findings suggest the improvement of housing ventilations
and larger space of living room for better oxygen circulation.
