Characterization of Polyhexamethylene Guanidine Oligomers in Solutions and Aerosols Emitted during Humidifier Use

Indoor Air, Volume 2024, Issue 1, 2024.
The behavior of polyhexamethylene guanidine (PHMG), the causative agent of many humidifier‐induced lung diseases, is not well known because of its various oligomer structures and analytical difficulties. The aim of this study was to identify different PHMG oligomer types both in solution and aerosols and to estimate the airborne concentration of ...

Pulmonary carcinogenic effects of subchronic inhalation exposure with long-term follow-up to polyhexamethylene guanidine phosphate in rats.

Scientific Reports
Polyhexamethylene guanidine phosphate (PHMG-p) is a biocidal compound linked to respiratory toxicity following exposure to humidifier disinfectants, but long-term pulmonary outcomes after inhalation remain insufficiently characterized.

Chemical injury history increases pulmonary susceptibility to PM2.5 inhalation: Toxicological evidence for risk assessment in a neglected vulnerable population

Environment International
Environmental health risk assessments typically prioritize vulnerable populations such as the elderly, children, and individuals with respiratory diseases. However, individuals with a history of chemical-induced lung injury are rarely considered, despite

Family-based case-control study of exposure to household humidifier disinfectants and risk of idiopathic interstitial pneumonia.

PLoS ONE, 2019
BackgroundIn Korea, several household humidifier disinfectants (HDs) were clinically confirmed to cause HD-associated lung injury (HDLI). Polyhexamethylene guanidine (PHMG) phosphate is the main ingredient of the HDs found to be associated with lung ...
