Study on the effects of relative humidity on daily and seasonal trends of particulate matter (PM 2.5 and PM 10) concentrations observed in Ateneo de Manila University campus from 2004−2005

Abstract

The seasonal effects of relative humidity to particulate matter (PM 2.5 and PM 10) concentrations are discussed using the two-year data from a beta-ray sampler gathered at the Ateneo de Manila University. During months with high relative humidity, a general decrease in PM concentration values was observed, and particularly for PM 10 concentration. During months with low relative humidity, PM concentrations were generally higher.
