Dirty air reduces the life span of more than a year
Air pollution reduces the global life expectancy by more than one year, the researchers report. According to a new study conducted by a group of leading environmental engineers and public health research, improving air quality can lead to a significant increase in life expectancy worldwide.
This is the first time that air pollution and life expectancy data were studied together to identify the global differences in how they affect the overall life expectancy.
What do we breathe?
Scientists have studied the contamination of the open air for particulate matter (PM) is less than 2, 5 microns. This small particles can penetrate deep into the lungs and breathing PM2.5 is associated with an increased risk of heart attacks, strokes, respiratory diseases and cancer. PM2.5 pollution comes from power plants, cars and trucks, fires, agricultural and industrial emissions. The scientists compared the levels of air pollution in different countries and life expectancy, and came to the conclusion that the dirty air has a great influence on life - reduces the life of about a year.
In the context of other significant effects, adversely affecting the performance of life, it's a lot.
