Air quality

A St. Louis environmental group wants to help urban farmers in north St. Louis and north St. Louis County monitor air quality. Climate Changents are placing air monitoring machines that test fine particulate matter on urban farms and schools.

Early in the coronavirus pandemic, concentrations of a harmful air pollutant dropped by more than 30% on average worldwide, Washington University researchers have found.

Over the next two years, the Nature Conservancy in Missouri will plant 100 trees in parts of north St. Louis County to help reduce air pollution and flooding.

Metropolitan Congregations United and engineering researchers at the Washington University are working with several churches in north and south St. Louis to measure air quality in areas with high amounts of pollution.

Black people and Latinos in St. Louis are more likely to live in areas with polluted air. Long-term exposure to air pollution is linked to faster coronavirus transmission, new research finds.

Health and meteorology experts say the growing presence of wildfire smoke in parts of Kansas and Nebraska could pose health risks to those who breathe it in. That concern is compounded, given the likelihood that vast and intense fires from California and surrounding areas will persist.

Burning fossil fuels has created a massive, global problem: climate change. New research from Washington University finds these fuel sources also have serious health consequences.

Across Missouri, more than 100 schools have spent over $3.5 million — often at taxpayers’ expense — snapping up ionization and other air-purifying devices in an attempt to keep kids safe from COVID-19. But experts warn the largely unregulated technology hasn’t been thoroughly tested in classroom settings and is “often unproven.”
