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 (semi-rural area) using portable monitors and GSE sensors. Daytime SO2and NO2levels 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 SO2and NO2during the dense haze episode in Perlis.
