Dangerous pollution chokes Thai regional hub

World | 11 Feb 2019 3:19 pm

Residents of Khon Kaen, an economic hub of Thailand’s northeast, have been struggling with serious air pollution for at least four consecutive days, The Nation in Bangkok reports.

The Air Quality Index as of yesterday stood at 206 and the level of PM2.5 particles per cubic meter of air hovered between 96 and 103 micrograms. All the readings were well beyond safe limits.

The index, beyond 200, signifies unhealthy air, triggering warnings to not venture outdoors without a face mask, while the safe level for PM2.5 is 50 per cubic meter, the daily said.

The World Health Organization has described PM2.5 – airborne particulates 2.5 micrometers or less in diameter – as "carcinogenic.'' Exposure to a dangerous level of PM2.5 poses health risk and in severe cases can lead to death.

Khon Kaen residents have been at risk since last Thursday. On February 7 the AQI touched 208 and PM2.5 hit 98. The following day the AQI stood at 213 and PM2.5 103. On Saturday the AQI was 206 and PM2.5 96.-Photo: The Nation.
