Abstract

Limited studies exist focusing onto personal exposure/deposition dose of particulate pollution in developing regions. In this study, as a first step, we present the results on how people spend their daily time in Metro Manila, Philippines. This information is critical in assessing the personal exposure/deposition dose of particulate pollutants. We found that: people spend less time at home on workdays than weekends (52% versus 70%); the time fraction spent at work/school increased with age until retirement; adult males spend less time at home than females (18% versus 28%); most of their time people spend indoors (84%). The biggest difference from previous studies – people in Metro Manila on average spends 11% of their daily time in transit traffic. This is up to 2.2 times more than in Europe, America, Korea or China. Longer times in transit traffic subjects the population of Metro Manila to a higher risk of increased exposure to toxic pollutants and adverse health symptoms. The main results of this study will be used in upcoming study on personal deposition dose of soot.
