MIT scientists have concluded that tens of thousands of premature deaths in the United States were due to tiny particles in the smoke of wildfires and agricultural fires, RT reported.
And the journal Environmental Research Letters notes that, in order to estimate the amount of PM2. 2003 and 2018 according to their natural or human source, using the atmospheric chemical transport model to calculate the impact of fires on the concentration of these particles in the atmosphere.
It became clear to the researchers that agricultural fires and forest fires mainly contributed to the increase in the concentration of PM2.5 resulting from natural fires, which occurred due to human activity, as the smoke resulting from these fires increased the concentration of polluted particles from 5 percent in 2003 to 10 percent in 2018.-
And it was shown that both sources of fires are the cause of more than 80 percent of the population’s exposure to PM2.-
According to the researchers, since this effect is related to fires caused by human activity, it can be greatly reduced by taking quick and drastic measures and measures to prevent agricultural fires from occurring due to climatic conditions. However, human-caused wildfires are difficult to deal with because they are accidental and unplanned.
