Bangkok Governor Chadchart Sittipunt says he would like the Environment Department to develop a device to trap smoke from the cooking of grilled pork skewers, after receiving many complaints about excessive smoke emitting from grilled pork stalls.

The governor disclosed what he described as interesting findings from two air quality measurement stations in the Bang Na area, which are close to a shopping mall where venders are selling grilled pork.

The findings, from December 2nd to 15th, show higher levels of PM2.5 dust in the area close to where grilled pork sewers are available than in nearby areas, said the governor, adding that he has assigned one of his advisors to find out if the smoke from the grilling is affecting people in the neighbourhood.

He said that the investigation was not, however, intended to stop the vendors from selling grilled pork, but in the hope that something can be done to reduce the PM2.5 dust they produce.

The Bangkok Metropolitan Administration has forecast increased PM2.5 in the atmosphere of the capital in the next seven days, which may affect the health of city dwellers.

Areas in Bangkok under close PM2.5 watch are Lak Si, Chatuchak, Khlong Toei, Phra Khanong, Bang Na, Phaya Thai, Din Daeng, Huai Khwang, Khlong Sam Wa, Min Buri, Saphan Soong, Taling Chan, Bangkok Noi, Thawee Wattana, Bang Khae, Nong Khaem and Bang Bon.

The public is advised to spend less time outdoors or to wear face masks.
