Quaternary ammonium compounds – new occupational hazards

open access: yesMedycyna Pracy, 2014
Quaternary ammonium compounds (QACs, quats) belong to organic ionic chemical agents which display unique properties of both surfactants and disinfectants. Their wide distribution in the work environment and also in private households brings about new occupational hazards. This paper reviews reports about the health effects of QACs.
