Air pollution in 28 areas in Bangkok and its peripherals this morning still poses  a health threat, with the amount of fine particulates (PM2.5 in size) in the air exceeding the safety level.

Pollution Control Department said that fine particulates in the 28 areas were measured to be between 39-97 microgramme/one cubic metre.

The areas include Kanchanapisek road in Bang Khun Thian district, Klong Chan area in Bang Kapi district, Intharapitak road in Thon Buri, Lat Phrao road in Wang Thong Lang district, Din Daeng road, Tambon Songkhanong in Phra Pradaeng district of Samut Prakan, Tambon Bang Saothong of Bang Saothong district of Samut Prakan, parallel road along the Rama II highway in Samut Sakhon.

The department also reported that dust particles beyond 10 micron (PM10) were also found to exceed safety level, measured at between 52-121 microgramme/one cubic metre, on both sides of Rama II highway in Muang district of Samut Sakhon province.

However, the department predicted that the situation in 19 roadside areas would slightly improve on Tuesday.

The worsening air quality in the city and its peripherals in the past few days has been blamed on automobile emissions and dusts from the construction of several infrastructure projects in Bangkok, resulting in haze covering up the city.

The problem has prompted Prime Minister Prayut Chan-o-cha to order the Bangkok Metropolitan Administration and the Pollution Control Department to come up with both short- and long-term measures to ease the problem.
