To protect the health of US residents, the Environmental Protection Agency must reduce the limit of particulate matter in the air. a group of scientific experts said in a draft report. Respiration of particles with a diameter of 2.5 μm or less (PM2.5) associated with heart attacks, decreased lung function, asthma attacks and premature death in people with heart or lung problems. In its draft report, the EPA’s Clean Air Scientific Advisory Committee says it agrees with the agency’s assessment published last year, which states: “A significant reduction in risk will result from a reduction in annual PM2.5 standard ». Most participants recommended a limit of 8-10 mcg / m3 air; the current standard, set in 2012, is 12 mcg / m3. During the time of former President Donald J. Trump, The EPA has proposed in 2020 to maintain this standard rather than procrastinate it, as recommended by agency staff. The American Chemistry Council has backed Trump’s plan, saying no additional controls are needed because U.S. air quality is improving. In its draft report, the advisory committee says: “The [scientific] the literature, as it expands, continues to show strong links with health effects, even despite the concentration of PM2.5 in the air over time declined. In the spring the board will complete the preparation of the report.
