The causes of air pollution vary dramatically from place to place.In India and China，the study says，emissions from residential heating and cooking drive air pollution by creating unhealthy quantities of smoke.Overall，residential heating emissions cause one third of air pollution­related deaths worldwide.

　　In highly regulated areas，like the United States，Europe and Japan，emissions from agriculture tend to be primary contributors to air pollution.Fertilizer used in agriculture releases ammonia into the atmosphere，a process that creates harmful particulate matter.Globally，air pollution from agriculture kills more than 600,000 people annually，the study finds.

　　The findings are consistent with a 2017 report from the World Health Organization that suggested that 7 million deaths occur annually due to both indoor and outdoor air pollution.

　　The study’s conclusions give a sense of urgency to efforts to reduce air pollution but present challenges because of difficulty regulating heating activity in people’s homes，according to study author Jos Lelieveld.People who live in the most affected areas should be provided with information about less toxic heating methods，he said.

　　“It’s important to reduce emissions from residential energy use，” Lelieveld said on a conference call for journalists.“You can’t ask people to stop eating and cooking，but you can provide better technologies.”
