A large portion of the Korean population has been exposed to toxic humidifier disinfectants, and considering that the majority of the victims are infants, the magnitude of the damage is expected to be considerably larger than what has currently been revealed. The current victims are voicing problems caused by various diseases, including but not limited to lung, upper respiratory tract, cardiovascular, kidney, musculoskeletal, eye, and skin diseases, etc. However, there has been difficulty in gaining validation for these health problems and identifying causal relationships due to lack of evidence proving that toxic humidifier disinfectant is the specific causes of extrapulmonary diseases such as allergic rhinitis...

A relief system applicable to the damages incurred by the humidifier disinfectants should be revised. It needs to create an institutional environment for the establishment of a risk management system inside corpotate. To this end, intruducing a set of legal systems, including punitive damages, must be reviewed. Also a law should be enacted to impose criminal penalties on the corporate deliberately killing or injuring a person by making reckless decisions. Finally, the government shall change the regulatory framework in a manner that validate that whether the safety check by the corpotrate having or capable of having informations on the products and their composing substances is adequate and sufficient or not...

The humidifier disinfectant disaster (HDD) was not a simple poisoning accident by biocides, but a singular disaster in history created by chemicals in household products. This disaster was a result of the failure of a system for the management of chemical and product safety. Since the management authority for chemical usage safety is different from those for chemical safety in products, many blind areas for chemical safety management in products still remain. The 'Act on the Registration and Evaluation, etc...

An analysis of patients and fatalities due to exposure to polyhexamethylene guanidine (PHMG) shows that PHMG causes mainly lung diseases such as pulmonary fibrosis. However, no research on the other organs has been conducted on this matter yet. So, an in-depth discussion on toxicological techniques is needed to determine whether or not PHMG is toxic to organs other than just the lungs. For the test of target organ toxicity by PHMG exposure, a toxicokinetic study must first be conducted. However, measurement method for PHMG injected into the body has not yet been established because it is not easy to analyze polymer PHMG, so related base studies on analytical technique for PHMG including radio-labeling chemistry must come first...
