| Summary: | Haze has became a public concern especially after the 1997 haze episode which
resulted from large-scale forest fires that caused transboudary spreading of air
pollution. Particulate matters are primarily responsible for creating haze in the
atmosphere as well as adverse effects on human health. Thus, both of the physical
and chemical characteristics of particulate matters are important when attempting to
elucidate particle toxicity. Particulate matters, which aerodynamic diameter equal or
less than 10µm (PM₁₀ ) were measured in the periods from 1997 to 2000 at UPM
station. High volume sampler (HVS) was used to collect most of the ambient particle
samples and a small portion was collected using particle counter. Sampling of
particulate matter was carried out from various emission sources such as peat swamp
fire at Sepang, biomass burning at paddy field and several types of vehicle exhaust.
Besides that, simulated peat soil and rice straw burning were also conducted in the
fumigation chamber to collect particulate matter. Chemical analysis was performed
by atomic absorption spectrophotometer (AAS) to identify ten kind of common trace
metals, namely potassium (K), zinc (Zn), magnesium (Mg), sodium (Na), calcium
(Ca), iron (Fe), manganese (Mn), lead (Pb), chromium (Cr) and copper (Cu). |
