Abstract
Malaysia frequently experienced haze since the 1990s. However, very dense haze
episodes rarely happened, especially in the state of Perlis, which located in the northern
part of the west coast of Peninsular Malaysia. In this study, sulfur dioxide (SO2) and
nitrogen dioxide (NO2) concentrations were measured during haze days and non-haze
days in October 2015 at two locations, namely; Ulu Pauh (rural area) and Jejawi (semirural area) using portable monitors and GSE sensors. Daytime SO2 and NO2 levels were
found higher during haze days (Ulu Pauh: 0.25 ppm and 0.07 ppm; Jejawi: 0.31 ppm
and 0.08 ppm) compared non-haze days (Ulu Pauh: 0.11 ppm and 0.05 ppm; Jejawi:
0.13 ppm and 0.06 ppm). Different locations displayed distinguishable concentrations
of SO2 and NO2 during the dense haze episode in Perlis.
