(HealthDay)—Burning fossil fuels account for about 100,000 air pollution-related deaths within the United States annually—however there are different much less apparent sources of lethal air pollution, a brand new examine warns.
“People usually think of power plants and cars, but nowadays, livestock and wood stoves are as big of a problem. It’s also our farms and our homes,” mentioned Sumil Thakrar, a postdoctoral researcher within the University of Minnesota.
Thakrar and his colleagues additionally discovered that whereas authorities laws have led to lowered pollution from electricity production and transportation, different sources have obtained much less consideration, together with agriculture and residential buildings.
Their evaluation of nationwide knowledge confirmed that about half of all PM2.5 air pollution-related deaths are from burning fossil fuels, with the remaining largely from animal agriculture, mud from development and roads, and burning wooden for heating and cooking.
The researchers mentioned most individuals know soot causes PM2.5. But different contributors embrace ammonia, which is launched from animal manure and crop fertilization, they famous.
“Essentially we’re asking, ‘What’s killing people and how do we stop it?'” Thakrar mentioned in a college information launch. “The first step in reducing deaths is learning the impact of each and every emission source.”
Jason Hill is a professor within the college’s Department of Bioproducts and Biosystems Engineering. He mentioned focusing on notably damaging pollution sources is a extra environment friendly and certain simpler manner of regulating air high quality.
“Think of springing a leak in your boat while out fishing. Why fret too much about how much water is coming in when what you really should be doing is plugging the hole?” Hill mentioned within the launch.
The examine was printed just lately within the journal Environmental Science and Technology Letters.
