WHO Releases New Global Air Quality Guidelines
For the first time since 2005, the World Health Organization (WHO) has updated their global air quality guidelines. According to WHO, over the past 16 years there has been a notable increase in evidence showing how air pollution affects various aspects of human health. WHO also estimates that exposure to air pollution causes 7 million premature deaths each year, and that also results in the loss of millions more healthy years of life. According to WHO’S new guidelines, particulate matter should be cut in half, annually, as compared to its 2005 figure, and nitrogen dioxide should be reduced by 75 percent. WHO also provides recommendations for ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide reductions.
