Volatile organic compounds (VOC) vaporize at or near room temperature—hence, the designation volatile. They are called organic because they contain carbon.
How is air quality regulated?
In the U.S., air quality is largely regulated by the federal government, which sets maximum allowable levels of pollution in different areas. States and local governments are then charged with enforcing those limits. The authors suggest regulators can improve this broad-brush approach by focusing instead on reducing emissions from specific sources.
What is the most harmful particulate matter?
Researchers focused on one particularly harmful pollutant: fine particulate matter, also known as PM2.5, which is associated with heart attacks, strokes, lung cancer and other diseases. In examining the data, they discovered that about half of all PM2.5 air pollution-related deaths are from burning fossil fuels, with the remaining largely from animal agriculture, dust from construction and roads, and burning wood for heating and cooking.
How can we improve air quality?
To improve air quality in the future, the authors suggest more drastic reductions of emissions from sources that are already regulated, such as electricity generation and passenger vehicles. They also suggest novel ways to target pollutant sources that have not been as extensively regulated, such as manure management, changing personal diets and improving formulations of cleaning supplies, paints and inks.
