Unlike in other developed countries

Unlike in other developed countries, there are a limited
number of studies concerning the chemical characterisation
of gaseous species and aerosols in Thailand (Thumanu et
al., 2009; Pongpiachan, 2013a; 2013b; Pongpiachan
et al., 2010, 2012a; 2012b; 2012c, 2013a; 2013b). In
this study, the authors postulate that the use of Fourier
Transform Infrared Spectroscopy (FTIR), combined
with numerous analogies of statistical analysis, assist in a
better understanding of the distribution pattern of organic
functional compositions of PM2.5, which can be subjected
to variations in sources and meteorological conditions
in northern Thailand. It is the objective of this study to
demonstrate the general application of organic functional
group analysis by FTIR as an innovative indicator to
chemically characterise PM2.5 at nine provinces in the
northern region of Thailand “before” and “after” the haze
episode in 2013. In addition, the incremental lifetime
exposure to PM2.5 and the application of FTIR spectral
features as an alternative “Biomass Burning” proxy will
be reviewed and discussed
