The limits for nine pollutants are tighter than the previous rule but are less stringent than a 2024 proposal.

Over the past four years, the Environmental Protection Agency has tightened restrictions on a host of pollutants and pollution sources, ranging from tougher tailpipe emissions standards for all ...

Exposure to fine particulate matter and traffic-related gaseous pollutants were associated with an increased risk for late-onset RA.

We know that reducing emissions from cars and factories is essential for cleaning our air, but new research reveals a chemical quirk in the atmosphere whereby slashing one pollutant can inadvertently ...

A research team has developed a new strategy to improve catalysts used to remove nitrogen oxides from industrial emissions. By using ethanol during catalyst preparation, the scientists significantly ...

Please provide your email address to receive an email when new articles are posted on . Exposure to nitrogen oxides increased risks for rheumatoid arthritis, Sjögren’s and systemic lupus erythematosus ...

Just a couple decades ago, nitrogen oxide emissions routinely plagued cities’ skies and their residents’ lungs. These polluting reactive nitrogen oxide gases from the tailpipes of combustion-engine ...

Recent advances in environmental technology have spurred the development of integrated biological and chemical processes to mitigate nitrogen oxides (NOx) emissions from flue gas. These processes ...

Inland waters, such as lakes, could be emitting much more of the air pollutants called nitrogen oxides than previously thought, suggesting that lakes’ emissions should be incorporated into future ...

Researchers have designed a new compound to remove nitrogen oxides, which constitutes a step towards the development of a system to purify the air under real conditions. The Chemical Institute for ...
