| Summary: | <p align="justify">Assessing the effects of air pollution to public health requires continuous and
accurate measurements of particle with aerodynamic diameter < 2.5 µm (PM2.5).
This study seeks to identify accurate and real time PM2.5 in Bandung urban site
using samplers from newly established monitoring network, Surface Particulate
Matter Network-SPARTAN. Sampling were carried out during January-August
2014 where an integrated filter-based sampler, AirPhoton® Filter Sampler, an
automated continuous sampler, AirPhoton® Nephelometer, operated in parallel
and simultaneous with a reference instrument, Harvard Impactor. 21 days
intercomparison study showed good agreement between PM2,5 mass concentration
measured by Harvard Impactor and Filter Sampler (R2=98.9% P-Value <.,001).
Nephelometer backscatter in 532 nm wavelengths (green) resulted hourly
estimates of PM2.5 mass concentration. Hourly estimates of PM2,5 for Bandung
urban site has average of ?????=34,087 ?g/Nm3 and standard deviation of µ=19,521
?g/Nm3. Hourly concentration of PM2.5 showed significant diurnal and seasonal
cycle. Multiple linear regression analysis showed influences of meteorological
factors; precipitation, wind speed, temperature, and relative humidity, to PM2,5
concentration in ambient air.<p align="justify"> |
