Advances on toxicity of polyhexamethyl guanidine / 环境与职业医学

ABSTRACT

Polyhexamethyl guanidine (PHMG) is a widely used guanidine disinfectant. Since a lung injury incident induced by humidifier disinfectant (PHMG was identified as a main component) was reported in Korea, its inhalation toxicity has attracted the attention of researchers. At present, there are few domestic studies on inhalation toxicity of PHMG. In this paper, based on the domestic and foreign studies of PHMG, the toxicities of PHMG, including inhalation toxicity and associated toxic mechanism, and other potential toxicities, such as liver toxicities, cardiovascular toxicity, immunotoxicity, and reproductive and developmental toxicity, were systematically introduced, revealing that the effects of use of PHMG in a non-standard manner on the body and its possible mechanisms, which could provide reference for the use of PHMG properly and to lay a theoretical foundation and provide a scientific basis for follow-up study.
