Human Health Risk to Ultrafine Particles in Jakarta
Abstract: In Jakarta, the main
pollution sources are vehicles and industry, with motorized traffic accounting
for 71% of the oxides of nitrogen (NOX), 15% of sulphur-dioxide (SO2), and 70%
of particulate matter (PM 10 ) of the total emission load. Both urban
population size and the fraction of the population that owns a pri-vate vehicle
are increasing. The study objective is to determine the numbers of ultrafine
particulate matter with an aerodynamic diameter of 0.1 mm or less, or PM0.1
inhaled by elementary school children, commute workers with private car and
commute workers with public transport. A cross-sectional study design is
implemented in Jakarta 2005. Ten elementary school children, ten commuters with
private car and ten commuters with public transports are purpo-sively selected
as subjects and measured personally for 3 x 24 hours using Condensation
Particle Counter (CPC) real-time personal exposure measurement (measured in
terms of the number of particles per cubic centimeter, or # cm-3). The average
concentration of ultrafine particulate matter of elementary school children at
home, on the road and at school is 29,254/cm3, 147,897/cm3 and 61,033/cm3
respectively. For those commuters with private car at home, on the road and at
office is 29,213/cm3, 310,179/cm3 and 42,496/cm3 respectively. For those
commuters with public transport, the concentration average of at home, on the
road and at office is found higher: 35,332/cm3, 453,547/cm3, and 69,867/cm3,
respectively.
