Air Analysis – News and Features

An unexpected link between wildfire events and the chemistry of the ozone layer has been uncovered in a new study.

The results show that greener and less densely populated cities have lower mortality rates, lower air pollution levels and lower urban heat island effect, but higher carbon footprints per capita.

Findings of a new study suggest restoring Great Salt Lake to a healthy water level would reduce disparities in harmful dust exposure experienced by different racial/ethnic and socioeconomic groups.

Asthma and symptoms of bronchitis in youth do not fully account for the association in a study that underlines the need to reduce pollution according to scientists at the Keck School of Medicine of USC.

Transmission electron microscopy (TEM) has been used to test for asbestos in samples for decades, but TEM can be expensive. Now, researchers have determined that scanning electron microscopy can achieve results comparable to TEM.

Many municipal landfills “burp” gas from decomposing organic matter rather than letting it build up. And burps from buried waste containing per- and polyfluoroalkyl substances (PFAS) can release these “forever chemicals” into the air.

Carbon capture, utilization and storage is a critical technology that reduces carbon dioxide emissions from hard-to-abate industrial sources. Researchers have now developed membranes that show high performance in carbon capture and could be deployed in large-scale industrial settings.

A new study helps to understand public perceptions of the link between climate change and extreme weather events, with wildfires being most confidently linked to climate change compared to hurricanes, flooding and tornadoes.

Researchers reporting in ACS’ Environmental Science & Technology measured concerning levels of ethylene oxide in Louisiana’s southeastern corridor with mobile optical instruments, a technique they say could improve health risk assessments.

Scientists have demonstrated a new method to extract valuable lithium from very dilute liquids – including seawater, groundwater and the “flowback water” generated from fracking and offshore oil drilling operations.
