Air pollution may be responsible for more than 2 million deaths around the world each year, according to a new study.
The study estimated that 2.1 million deaths each year are linked with fine particulate matter, tiny particles that can get deep into the lungs and cause health problems.
Exposure to particle pollution has been linked with early death from heart and lung diseases, including lung cancer, the researchers said; meanwhile, concentrations of particulate matter have been increasing due to human activities. The study also found that 470,000 deaths yearly are linked with human sources of ozone, which forms when pollutants from sources such as cars or factories come together and react. Exposure to ozone has been linked to death from respiratory diseases.
Most of the estimated global deaths likely occur in East and South Asia, which have large populations and severe air pollution, said study researcher Jason West, an assistant professor of environmental sciences at the University of North Carolina at Chapel Hill.
"Air pollution is an important problem. It's probably one of the most important environmental risk factors for health," West said. The study suggests that improving air quality around the world would increase life expectancy for some, he said.
While some studies have suggested that climate change can make air pollution more deadly, the new study found that climate change had only a small effect on air pollution-related deaths.

The researchers are to be congratulated for admitting that "climate change" (what ever they mean with it) has "only a small effect" on air pollution deaths. They will certainly face criticism from the global warming alarmist crowd, who will see to it that this new study will receive no attention in MSM media. Neither will this real problem be discussed by experts and politicians at large scale annual international mega conferences, in contrast to "climate change".
