Academics reveal that the government solves PM 2.5, it is right to ask the UDD to avoid using a car Crisis home workform
At 12.00 on December 15 at the Government House Mr. Supat Wangwongwattana Faculty of Public Health Thammasat University Advisor, Thai Environment Institute And former Director-General of Pollution Control Department Said that now the government has taken the right path Because in the past there have been studies collecting academic data from both the Department of Poisoning Control. Meteorological Department And the Department of Health as a basis for formulating policies and measures The situation arising from climate that is a matter of science. Causing in the Bangkok area to come with a still weather Fog in the morning
Then the late morning turned into dust. Which solving problems during this time will be difficult to solve them all But can alleviate the situation There are 3 points for solving the problem: 1. A source of air pollution exhaustion or PM 2.5; 2. Eliminating airborne pollutants falling into the soil and 3. Protecting people who are receiving dust from entering the body as well. The wearing of masks at all 3 points, the government is in progress.
For the source of academic information over the past 2 years, it was found that the small dust source PM2.5 in Bangkok came from using a diesel engine. Causing the black smoke to be accumulated so that we can see it with the naked eye While open burning in Bangkok is few but mostly due to the burning of agricultural materials around Bangkok. Such as Pathum Thani, Nonthaburi, Phra Nakhon Si Ayutthaya, which is blown by the north wind in Bangkok, especially in the southeast of Bangkok, making the area of Bang Khun Thian and Samut Sakhon Province as a red area.
As for the car’s diesel consumption, there is still relatively high sulfur. If using diesel with very low sulfur Now that the 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%, helping to reduce dust. Expected to meet the needs of solving long-term problems in the future
When asked whether the volatile mass of water vapor in the air is also dust or haze, Mr. Suphat said that in the academic case, if it is morning fog, it is not considered dust. But the occurrence of fog in academic need has a core of water vapor that condenses Therefore, most periods will be foggy. It is not considered as direct dust, however, PM 2.5 small dust will rise during the morning with heavy traffic. And in the afternoon after work that goes up until 24.00 before the situation will subside until the morning
Therefore wanting to ask for cooperation, the public should try to avoid, if not necessary, should not drive to work Asked to use public transportation instead To reduce the number of small dust emission PM 2.5, while government agencies and non-governmental organizations can work from home or not. To reduce travel in times of crisis and reduce the use of cars in Bangkok as much as possible to alleviate the problem of small particles PM 2.5
When asked if we implement government measures And all cooperation measures have a small dust chance. Will PM2.5 disappear from Thailand? Mr. Supat said there is an opportunity, but it will not happen within 1-2 years. Long-term action must be taken to correct it. However, this kind of situation will continue to happen. But will occur for a short period of time until the end of winter
