Yesterday, February 7, the U.S. Environmental Protection Agency (EPA) announced stronger particulate matter standards that will help rid Wisconsin’s air of deadly pollution. The new National Ambient Air Quality Standards for particulate matter are 9 micrograms per cubic meter (µg/m3) for the annual standard and 35 µg/m3 for the 24-hour standard. The Wisconsin Medical Society (WisMed) partnered with Healthy Climate Wisconsin to encourage the EPA to produce strong standards.
"I applaud the EPA for setting strong and science-based particulate matter standards that will protect public health and the environment. This is a major win for all of our patients in Wisconsin. I am proud of Wisconsin’s doctors for weighing in on this," said Joel Charles MD, MPH, WisMed board member and co-founder of Healthy Climate Wisconsin.
Fine particulate matter, or soot, is an extremely harmful pollutant. It is a mix of metals, organic chemicals and acidic substances that are so small they can be inhaled deeply into the lungs and enter the bloodstream. Exposure to particulate matter has been shown to cause increased stillbirths, preterm births, asthma, cardiovascular disease, diabetes, cognitive impairments and premature death.
These standards had not been updated since 2012. Under the existing particulate matter standards, more than 63 million Americans experience unhealthy spikes in daily particle pollution, and more than 20 million Americans experience dangerous levels of soot on a year-round basis. In addition, the health burdens of particulate matter pollution are disproportionately borne by poor people and communities of color living near heavily polluting facilities and high-traffic roadways.
“High levels of particulate matter are at the core of health care disparities, as we have experienced among underserved populations in Wisconsin,” said Rene’ Settle-Robinson, DPM, a surgeon at Outreach Community Health Center. “The new standards go a long way in creating health equity for all Wisconsinites.”
The EPA’s new particulate matter safeguards will save lives — annually preventing up to 4,500 premature deaths and 290,000 lost workdays, yielding up to $46 billion in net health benefits. Stronger standards help those most vulnerable to the negative health effects of particulate matter pollution, including children, seniors, communities of color and people with chronic illness.
WisMed called on the EPA to set the annual National Ambient Air Quality Standards for particulate matter no higher than 8 micrograms per cubic meter (µg/m3) and the 24-hour standard no higher than 25 µg/m3. These were the lowest levels the EPA said it would consider in 2023. Health professionals will continue to advocate for even lower particulate matter standards in the coming years because there is no safe level of particulate matter for health.
