The Salt Lake Tribune | Utah’s current air quality monitoring system is struggling to adequately track dust storms originating from the drying Great Salt Lake, raising health concerns due to toxic sediment exposure. State scientists and researchers emphasize the urgent need for expanded monitoring sites and funding to measure PM10 levels and provide timely public alerts, especially as lake levels continue to drop.

KKTV | The City of Manitou Springs will hold an outdoor Air Quality Awareness Week event on Wednesday, May 22, from 10:00 a.m. to 2:30 p.m. at Memorial Park. Residents are encouraged to walk or bike to school and attend the event to learn how to reduce their impact on air quality.

Canary Media | Air pollution from Midwest steel mills continues to harm local communities, with research suggesting cleaner-burning alternatives could improve conditions. Meanwhile, debates around fossil fuel plant replacements, clean energy investments, and electric grid modernization are intensifying across Indiana, Michigan, and Minnesota, reflecting broader tensions between clean energy goals and current economic or political pressures.

MPR News | A widespread rainfall across central and southern Minnesota delivered up to 4 inches in some areas, significantly easing drought and improving air quality, with some areas seeing record-low pollution levels. While the rain missed northern fire zones, the Memorial Day weekend forecast looks mostly sunny and dry with highs in the 60s, and long-range outlooks suggest a warmer-than-average summer.

Maricopa County | The Arizona Department of Environmental Quality has issued an Ozone High Pollution Advisory for Maricopa County on May 21, 2025, due to expected ozone levels exceeding federal health standards. Residents, especially children and those with respiratory conditions, are advised to limit outdoor activity and follow recommended actions like driving less and avoiding wood burning to help reduce harmful emissions.

Portsmouth City Council | Portsmouth’s new “Air Quality Heroes” campaign highlights the benefits of sustainable travel by sharing real-life stories of residents using public transport, cycling, and walking. Through short films, the initiative aims to challenge misconceptions and encourage behavior changes that support cleaner air and healthier communities.

Arizona Emergency Information Network | The Arizona Department of Environmental Quality has issued a High Pollution Advisory for ozone on May 21, 2025, warning that levels may exceed federal health standards and urging residents to limit outdoor activity and reduce emissions. Residents are encouraged to drive less, avoid using leaf blowers, delay painting projects, and eliminate wood burning to protect public health, especially for children and individuals with respiratory conditions.

Olympic World Library | This narrative review, prepared for the IOC, compiles current evidence on how air pollution affects athlete health and performance, especially during major sporting events held in areas with poor air quality. It underscores growing concerns among organizers and athletes and highlights critical research gaps that need addressing to guide safer competition practices.

IDEAS/RePEc | Air pollution from Kaohsiung Linhai Industrial Park significantly depresses nearby housing prices, with sulfur dioxide (SO₂) having the most pronounced effect due to its visible haze. The study highlights the social costs of industrial overdevelopment and calls for regular assessments of the “shadow price” residents pay, offering policy recommendations for sustainable industrial planning.

Science News | The AI model Aurora can generate highly accurate weather forecasts—including cyclone tracks and air pollution—in seconds, outperforming traditional systems and offering new capabilities to regions lacking supercomputing resources. Trained on over a million hours of atmospheric data and fine-tuned for specific tasks, Aurora marks a major advancement in fast, scalable Earth systems prediction.
