Air pollution in Bangkok expected to get worse due to “cold spell”

Air pollution in Bangkok is expected to get worse over the next few days as pollutants are getting trapped in the atmosphere thanks to a recent cold spell and a lack of wind to blow the haze away from the city. In response to the unhealthy air pollution, The PM’s Office permanent secretary says he has asked several ministries to step up efforts in combatting the PM2.5 micron ‘dust’ particulate that has blanketed the city.

He says that the issue has been contained so far due to Covid-19 measures which have made many people work from home.

“But vehicle exhaust fumes, construction sites and burning garbage in open areas is not helping.”

“To add to the problem, the cold spell is creating an “inversion layer” as meteorologists call it, which stops air below it from rising and trapping pollutants.”

As usual, Bangkok officials are looking to some of the smaller, localised traffic issues to blame, although the annual “smoke from the north” problem is the key and overriding issue regarding Bangkok’s smog problem months. The local traffic pollutants, whilst ever-present, don’t cause the skyline smog and haze for the rest of the year.

And when the Thais refer to a “cold spell” it usually means the ambient temperature has dropped to the low 20s. In other parts of the world that would be considered a heat wave!

The secretary says police and other officials are being asked to curb traffic build-ups at intersections as some had seen a sharp increase in dust pollution. Motorists are also being advised to take their cars for routine engine check-ups but some owners are refusing, saying their cars are new and not releasing black smoke. Public transportation vehicles are also being checked for emissions that could further add to the pollution issue in the country’s capital.

Meanwhile, PM Prayut has recently asked people to avoid large gatherings out of what he says is “concern” for their health after the recent cold spell from China hit the nation. But, more particularly, he pointed out political gatherings and has also asked everyone to adhere to social distancing and mask wearing to help curb the recent outbreak of Covid-19 that has swept the country in the past couple of months.
