Ozone generation and chemistry from 222 nm germicidal ultraviolet light in a fragrant restroom

Devices using 222 nm germicidal ultraviolet light (GUV222) have been marketed to reduce virus transmission indoors. However, GUV222 generates ozone which can react with gases and surfaces to create undesirable air byproducts.

Unrecognized volatile and semi-volatile organic compounds from brake wear

This study shows that volatile and semi-volatile organic gases are emitted during light and heavy braking. These emissions will remain as we transition to zero exhaust emission vehicles and must be included in air pollution and climate assessments.

Improving model representation of rapid ozone deposition over soil in the central Tibetan Plateau

Ozone deposition velocity with a daily mean of 0.49 cm s−1 was observed in the Tibetan Plateau and rationalized by local meteorological and soil conditions. Our research suggested widespread ozone deposition velocity over soil of 0.1–0.7 cm s−1.
