At 10pm on Thursday, Bangkok Governor Aswin Kwanmuang, Deputy Interior Minister Niphon Bunyamanee, and deputy Metropolitan Police chief Maj-General Jirasan Kaewsaeng-ake launched the “Bangkok Big Cleaning Day” activity in a bid to reduce dust particles less than 2.5 micrometres in diameter (PM2.5) in the air by spraying water as well as cleaning roads and public facilities.
“The activity will be carried out in 50 districts of Bangkok, while tonight it will be kicked off in five locations,” said Aswin. “They are Din Daeng district, the Wong Wian Yai intersection in Thongburi district, Central Rama II in Bang Khun Thian district, Sanam Luang 2 in Thawi Watthana district, and in front of Nong Khaem district office.”
Niphon added that the Interior Ministry had ordered contractors in Bangkok and its perimeter areas to hold off on construction projects during January and February to reduce the source of dust and air pollution in the city.
“We have also asked provinces around Bangkok to stop burning of garbage and leftover crops, which are one of the sources of PM2.5 that could be carried by wind to Bangkok areas.”
