State academics solve PM2.5, right when applying for NACC to avoid driving to work Suggest green lights to work at home Indicating future is likely to expire from Thailand Probably won’t happen 1-2 years
On December 15, 2020 at the Government House, Mr. Supat Wangwongwattana Faculty of Public Health Thammasat University Advisor, Thai Environment Institute and the former Director General of the Department of Pollution Control said that the government has now taken the right path Because in the past there have been studies that collect academic data from both the Department of Poison Control. Meteorological Department and Health Department as the basis for policy and action formulation The weather situation is a matter of science. Causing the Bangkok area to have calm weather Foggy morning Then the early morning turned to dust.
Stay on top of the news Press to follow the live news line.
Mr. Supat said that solving the problem during this time will be difficult to solve. But it can alleviate the situation There are 3 points to solve the problem: 1. A source of depletion of air pollution or PM 2.5, 2. Eliminate air pollutants that fall to the ground, and 3. Protect people who receive dust to that they do not enter the body as well. The use of masks in the 3 points, the government is in progress.
“For the academic data source of the last 2 years, it was found that the small source of PM2.5 dust in Bangkok came from the use of a diesel engine. Causing black smoke to come out until it accumulates Allowing us to see with the naked eye While the burning of the open air in Bangkok is less But most of it is due to the burning of agricultural materials in and around Bangkok. Like Pathum Thani, Nonthaburi, Phra Nakhon Si Ayutthaya That was brought by the north wind in Bangkok Especially in the southeast of Bangkok. Causing Bang Khun Thian area AND Samut Sakhon province A red zone
The car’s diesel consumption is still relatively high in sulfur. If You Use Very Low Sulfur Diesel Now That Oil Companies Are Cooperating Technical tests have shown that it can help reduce the discharge of dust in diesel fuel. By reducing it by more than 20 percent, it helps reduce dust. It is expected to meet the needs of long-term problem solving in the future.
When asked if the volatile mass of water vapor in the air is also dust or mist, Mr. Suphat said that in the academic case, if it is morning mist, it is not considered dust. But the appearance of fog in the academy must have a core of water vapor that condenses Therefore, most of the time it will be fog. Do not hold the powder directly. The little PM2.5 dust will wake up during the morning with heavy traffic. And in the afternoon after work that rises until midnight before the situation subsides until the morning. Therefore, wanting to ask for cooperation, people try to avoid If not, you should not drive to work. He was asked to use public transportation instead to reduce the amount of small emissions of PM2.5 particles, while government agencies and private organizations consider whether they can work from home or not. Reduce travel in times of crisis and reduce car use in Bangkok as much as possible to alleviate the problem of small dust PM2.5
When asked whether to implement government measures And all cooperative measures, is there a possibility that PM2.5 fine dust will disappear from Thailand? Mr. Supat said that there is an opportunity, but it will not happen in 1-2 years. Long-term measures must be taken to solve it. However, this type of situation will continue to occur. But it will happen for a short period of time until the end of winter.
