Forest fire crisis and toxic haze In our northern region, it is still a problem for many generations. And still remains an important issue that still has no solution Which will occur every year during the summer The frequency of wildfire occurring both naturally occurring and people making 73.17% of the forest fire occurrences throughout the country.
Smog caused by forest fires Caused by incomplete combustion Which will cause smoke, dust, fog, ash and various toxic gases such as carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2) and ozone (O3), etc. These pollutants will Contaminated with haze particles Of course, the area where the air is dry, without the wind blowing, is more vulnerable to pollutants than other areas. Because of these dust Can be suspended in the air for a very long time The smaller the size, the more suspended it can be for years.
There have been reports from the AFP news agency. The death toll from the wildfire occurring around the world Is estimated at 339,000 people / year. The Southeast Asia region is at the top 2 with about 110,000 deaths per year.
In Russia, in the year 2010 there was a big forest fire which caused an average of 700 people per day in Moscow. And the total death toll could be as many as 15,000. Hot and inhaling toxic smog Although there are no reports of deaths from forest fires in Thailand But there are more than 10,000 people affected by respiratory and heart health in the north.
Air pollution in the north is higher than elsewhere. Because the landscape of the northern region is surrounded by mountains Causing pollution accumulation Plus also receiving high pressure from China Causing the morning to be humid When water droplets in these moist air Combined with pollutants in the air, it will be a toxic fog covering the city.
The pollutants in the air are in two forms: gas form and suspended particle form. Which is contaminated in the air we breathe every day Which our health will be affected by pollutants vary according to the size of dust, concentration and duration of contact Including the physical condition of the person receiving the pollution too
Particle size that is harmful to human health is Particles that are 2.5-10 microns in diameter, also known as Particulate Matter, PM10 and particles with a diameter smaller than 2.5, also known as Particulate Matter PM2.5. The smog is contaminated. with Dust, PM2.5 and PM10. By this PM2.5 dust can easily enter the lungs and spread throughout the body.
Due to the measurement of small dust particles, PM2.5 in government agencies is still not standard. But the results of the measurement of the small amount of dust (PM10) of the Pollution Control Department in the upper northern region From 1 January to 5 March 2012, the average PM10 value in the 24-hour period exceeded the standard of 120 micrograms per cubic meter. Which the province with the highest PM10 24 hours, the standard value is more than twice the standard Try to imagine that PM2.5 that has been contaminated for a longer period and how much more severe it will be. Can't see, not that there is no No, the report is not that it doesn't exist. Therefore, we should not be underestimated.
