Bangkok air quality still unhealthy despite drop in PM2.5 levels


In spite of the significant drop of pollutants in Bangkok on Sunday, the air quality blanketing the capital and its neighboring places is still considered “unhealthy”.

According to the Pollution Control Department (PCD) as reported by Bangkok Post, the levels of PM2.5 pollutants as of Sunday exceeded the safety threshold of 50 microgrammes per cubic metre (µg/m³) at 13 roadside air quality monitoring stations and eight other general stations in the city proper.

Rama II Road in Samut Sakhon’s Muang district recorded the highest reading, where PM2.5 levels reached 85 µg/m³.

PCD said PM2.5 levels in the area on the previous day hovered around 119 µg/m³.

Any PM2.5 readings of above 50 µg/m³ are considered unsafe.

By midday Sunday, the level of PM2.5 particles decreased dramatically. Four areas were found to have PM2.5 levels that continue to exceed the safety threshold — two roadside areas and two general sites, said the PCD.

PCD continues to encourage people not to burn waste in open pits, avoid using vehicles emitting black smoke, and switch from personal cars to public transport, the report added.
