Review Times | Community members in southwest Indiana are taking air monitoring into their own hands as pollution from nearby coal plants continues to affect local health, even as federal programs face cuts. With the EPA proposing to roll back greenhouse gas reporting requirements and reduce funding for air monitors, residents and advocates warn that losing this data threatens public accountability and hampers efforts to address environmental justice and climate change.

Washington Energy Report | On May 23, 2025, FERC reaffirmed its approval of Venture Global’s CP2 LNG export terminal and CP Express Pipeline in Louisiana, finding the projects environmentally acceptable and consistent with the public interest. Despite concerns raised by environmental groups about air quality impacts, FERC concluded—based on supplemental analysis—that the projects meet NEPA requirements, advancing them closer to final approval.

News-Medical.net | A new review published in iScience links air pollution to neurodegenerative diseases through epigenetic modifications, revealing how pollutants can alter DNA methylation, non-coding RNAs, and histone markers—potentially triggering early brain damage. The findings highlight the urgent need for long-term studies, early detection tools, and stronger workplace protections to mitigate risks, particularly among vulnerable and high-exposure populations.

EcoWatch | A new study from Emory University has identified molecular pathways linking fine particulate matter (PM2.5) exposure to increased risks of pre-term and early-term births, particularly among Black pregnant women in urban Atlanta. By pinpointing specific metabolites and disrupted biological processes, the research offers insight into how air pollution harms maternal health and paves the way for targeted clinical interventions.

CBS News | New York City and surrounding areas are under an air quality alert Thursday due to smoke from Canadian wildfires, with AQI levels expected to reach 108—unhealthy for sensitive groups. Hot and humid weather is worsening conditions, though gradual improvement is expected over the coming days.

EurekAlert! | A new international study reveals that aged desert dust particles act as chemical reactors, significantly contributing to secondary organic aerosol (SOA) formation—contradicting long-held assumptions that SOA primarily forms in fine particles. These coarse, water-containing dust particles could account for up to two-thirds of SOA in dusty regions, reshaping our understanding of air pollution and its climate and health impacts.

Block Club Chicago | Smoke from central Canadian wildfires pushed Chicago’s air quality into the “unhealthy” range for the general public on Thursday, prompting an air quality alert and the state’s first Air Quality Action Day of 2025. Health officials extended the alert through Friday and urged residents to limit outdoor activity and reduce pollution, with improvement expected by Saturday.

BayToday.ca | Smoke from western Canadian wildfires has degraded air quality across eastern Canada and parts of the U.S., with North Bay experiencing AQHI levels ranging from “unhealthy for sensitive groups” to “unhealthy.” Health officials advise vulnerable populations to limit outdoor activity, stay indoors with filtered air, and monitor local air quality alerts as smoke persists into Friday.

Maine Public | The Maine DEP has issued air quality alerts for ozone and particulate pollution due to heat, wildfire smoke from Canada, and transported emissions from the Midwest and mid-Atlantic. Sensitive groups are advised to limit outdoor exposure through Friday, with conditions expected to improve over the weekend.

Haliburton, Kawartha, Pine Ridge District Health Unit | As wildfire smoke from Saskatchewan and Manitoba threatens southern Ontario, local health units are urging residents to monitor Environment Canada’s Air Quality Health Index and take protective measures. Vulnerable populations are especially at risk, and the public is advised to stay informed, create clean air spaces, and limit outdoor activity when air quality worsens.
