The World Health Organization (W.H.O) has just released the result of their most comprehensive air quality study to date; conducted by 12 scientists over the past 18 months, which concluded that 92% of people around the world breathe unhealthy air. The WHO research measured particulate matter in the air, such as “sulphates, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water.” It did not account for known pollutants such as nitrogen oxides or ozone — meaning that these are likely conservative figures. They also estimate that over 6.5 millions deaths annually are directly associated to health problems caused by unhealthy air, over half of which are from indoor air quality. María P. Neira, director of the W.H.O.’s Department of Public Health and Environment, has also noted that “the trends are still going in the wrong direction.” The major contributors to outdoor air pollution are mostly human triggered such as dirtier fuel sources and transportation. The EPA estimates that indoor air is 2-5 times worse than outdoors, and a recent study shows 90% of homes contain toxic dust. To help monitor your exposure outdoors, the Environmental Protection Agency’s website airnow.gov, along with many state and local agency sites allow you to see outdoor air quality in your area. HomeLab identifies key pollutants inside your home that impact health such as particulates and toxic VOCs, and shows you how to remove them. Their app and experts will also review your home and help create a healthy environment. Learn more about how it works here.
