A substance that is released into the atmosphere; the cause of air pollutionMay 7, 2019 · Irritant/Corrosive - Normally these types of atmospheric hazards are divided into primary and secondary groups. Primary irritants exert no systemic toxic effects because the products formed by them on tissues of the respiratory tract are non-irritant and other irritant effects are so violent as to obscure any systemic toxic action. A separate irritant criterion accommodates cases when there is a significant irritant response but less than the mean score criterion for a positive test.
