Grist.org | As Canadian wildfire smoke continues to blanket parts of the U.S. and even reach Europe, experts warn that proposed EPA budget and staffing cuts threaten the nation’s ability to monitor air quality and protect public health. Scientists stress that losing federally funded monitoring networks could undermine vital research and public alerts, leaving communities—especially vulnerable ones—less prepared for rising pollution risks linked to climate change.

CFTK-TV | A special air quality warning remains in effect for parts of Northwest and central British Columbia due to wildfire smoke, with conditions expected to persist for 24–48 hours. Residents are advised to limit outdoor activity, monitor symptoms, stay cool indoors, and follow local health and emergency guidance.

ScienceDirect.com | Researchers developed a high-resolution machine learning model to forecast hourly VOC concentrations in Shanghai, producing 1 km resolution maps up to 24 hours in advance. The LightGBM model outperformed others in accuracy, offering a powerful new tool for air quality management and pollution control strategy planning.

ACS Publications – American Chemical Society | Researchers have developed SoC-POM, a real-time AI algorithm embedded in satellites that detects abnormal levels of PM2.5, PM10, and ozone with high accuracy and low latency. Successfully tested on Himawari-8 and -9, the system enables rapid air quality alerts, enhancing public health responses to pollution exposure.

Suffolk County Government | An ozone-related air quality health advisory is in effect today for Long Island, with residents—especially sensitive groups—urged to limit outdoor activity during peak afternoon and evening hours. Officials warn that elevated ozone levels can cause respiratory irritation and other health issues, particularly on hot, sunny days.

CBS News | A dangerous heat wave is gripping the Philadelphia region through Wednesday, with temperatures soaring above 100°F and nighttime lows offering little relief. A Code Orange air quality alert is also in effect, prompting health officials to activate emergency cooling centers and urge vulnerable populations to stay indoors and hydrated.

MLive.com | An air quality alert is in effect through Tuesday for Cass and Berrien counties in Michigan due to elevated ozone levels reaching the “Unhealthy for Sensitive Groups” range. Residents, especially those with respiratory conditions, are advised to limit outdoor activity, avoid pollution-producing behaviors, and stay informed through local weather updates.

York Dispatch | A Code Orange Air Quality Action Day has been declared for York County and surrounding areas on Monday due to high ozone levels worsened by extreme heat and stagnant air. Sensitive groups are urged to limit outdoor activity, and residents are encouraged to reduce emissions by conserving energy and limiting vehicle use.

FOX43 | The Pennsylvania DEP has issued a Code Orange Air Quality Action Day for June 23 due to high ozone levels driven by heat and stagnant air, affecting central and eastern counties. Sensitive groups are advised to limit outdoor activity, and residents are urged to take pollution-reducing actions like carpooling and conserving energy.

RiverheadLOCAL | A ground-level ozone advisory is in effect today for Long Island, with air quality expected to be unhealthy for sensitive groups due to elevated ozone levels caused by summer heat and vehicle emissions. Officials urge residents, especially those with respiratory conditions, to limit outdoor activity and adopt energy-saving practices to reduce pollution.
