High PM2.5 concentrations in East Coast Peninsular Malaysia were spotted between August and September 2019
Large-scale biomass burning (BB), such as peatland combustion, emits large amounts of aerosols that lead to transboundary smoke events. Therefore, high pollution in the atmosphere has an adverse impact on human health, society, and environment. Aerosols is referred to fine particulate matter (PM2.5) that is suspended in the atmosphere for at least several hours and degrades the air quality. When the PM2.5 concentrated in the atmosphere, it reduced visibility and introduced the hazy condition. Thus, it has been used as an indicator to identify the haze event.
In 2019, anomalously high ambient PM2.5 concentration based on New Malaysia Ambient Air Quality Standard (NMAAQS) was recorded, with high pollution episodes in August to September at the East Coast Peninsular Malaysia (ECPM). This incident was linked to the biomass burning activities occurred in Indonesia. However, Pahang and Kelantan having almost similar trends of PM2.5 while Terengganu trends is the lowest. This condition probably was influenced by the location of the station which it did not receive much pollutants from the transboundary smoke event at the Terengganu station.
