Today the Environmental Protection Agency (EPA) announced a draft pollution standard for soot that will reduce one of the most dangerous forms of air pollution, saving thousands of lives and preventing tens of thousands of heart attacks every single year. Unfortunately, it is sure to come under attack by big polluters, so we will need to stand together to defend it.

Soot, also known as particulate pollution, is the most harmful type of air pollution. Soot pollution is a significant health threat because these very fine particles, which come from burning fossil fuels, can be inhaled and lodge in the lungs, causing serious heart and lung problems.

Numerous scientific studies link soot exposure to a variety of serious health problems, including difficulty breathing, heart attacks, asthma attacks, chronic bronchitis, irregular heartbeat, and eve premature death in people with heart or lung disease.
