The human body's exposure to ozone in indoor spaces generates highly reactive hydroxyl (OH), radicals which are largely responsible for the oxidation of most pollutant gases, researchers report. The ...

The chemical cycles in the troposphere along with pollutants of human and natural origin can alter the composition of the air and effect local, regional and global environmental quality, according to ...

A NASA scientist tasked to develop an instrument to detect hydroxyl has instead accidentally created a highly accurate ozone detector. The Rapid Ozone Experiment, or ROZE, can outperform even the best ...

We humans spend the vast majority of our time indoors, and we are constantly bombarded with compounds emitted from environmental sources. But we aren’t just passive targets of a chemical barrage. Our ...

A chemical reaction long assumed to be unimportant in urban air quality may be a significant source of ozone, the major component of smog. Hydroxyl (OH) radicals, among the most reactive natural ...

A research team has fully characterized a key chemical reaction that affects the formation of pollutants in smoggy air in the world's urban areas. When applied to Los Angeles, the laboratory results ...

LIMA — With the goal of making its facilities safer during the coronavirus pandemic, Allen County has purchased 36 Titan Hydroxyl Generators that claim to clean the air by producing reactive molecules ...

April 30 (UPI) --Researchers originally designed the ROZE instrument to detect hydroxyl, which rids the atmosphere of methane. But tests showed the instrument was surprisingly good at measuring ...

An international effort to measure air quality in South Korea, a region with complex sources of pollution, may provide new insights into the atmospheric chemistry that produces ozone pollution, ...

NASA research scientist Tom Hanisco set out to build an instrument capable of measuring a short-lived chemical that cleanses the atmosphere of methane -- a potent greenhouse gas -- but found instead ...

Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus’s dense atmosphere.
