The objective of this study is to review the safety and health information displayed on containers of humidifier disinfectants (HD). We summarized not only general characteristics related to the marketing and manufacturing of HD, such as the duration sold and the name of the company, but also the safety and health information, such as identification of disinfectants, recommended use volume, and precautions. All of this information was reviewed by HD brand. We collected safety and health information from 31 HD brands. We found that companies that sold and manufactured HD brands differ. Two companies were found to sell their HD without permission after 2011 when the health effects caused by HD were widely known. The name of the disinfectants were not identified on the container of HD. The recommended volumes were found not to be based on toxicological evidence and set without consideration of the level of susceptibility of users. Most companies displayed phrases such “this HD is safe for humans, even children” on the front of the container. No inhalation and skin toxicity precautions were provided. In conclusion, most HD did not properly display information related to safety and health to protect the health of HD users. There has been no official investigation to evaluate the risks posed by HD, such as the sales volume by HD, identification of chemical disinfectants, or their concentration, nor have there been actions to control the chemical quality of HD. In addition, government actions to punish the malicious practices of companies that manufactured and sold HD were found to inappropriate

Objective: This study aimed to report the level of extremely low frequency-magnetic field (ELF-MF) emitted by portable hand-held fans (HHF) and to discuss the methodologies for determining the health risk of ELF-MF for HHF products. Method: ELF-MF was monitored at eight locations by distances in the vicinity of HHFs. A total of 13 HHF brands on the market were randomly selected. A portable ELF-MF monitor MDEX II was used to measure the ELF-MF level in the range of 40-800 Hz with a resolution of 0.01 µT. This study also examined the frequency results of a total of 45 HHF products investigated by the Korean Ministry of Science and ICT (KMSICT). Results: ELF-MF higher than 0.3 µT was found to be emitted at a distance of less than 20 cm from 12 HHF. ELF-MF emitted from four products was found to exceed the reference level (83.3 uT based on 60 Hz) recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). KMSIT reported that the principle frequency emitted from the HHFs ranged from 54 Hz to 284 kHz, without the level of LEF-MF. Unscientifically, the KMSICT used the reference level by ICNIRP as the chronic level and concluded that all HHFs are safe with a basis of 1.2-36.0% less than the reference level. Conclusion: The HHF emitted much higher levels of ELF-MF than 0.3-0.4 µT, which is regarded as the reference level for childhood leukemia. The risk of HHF should be examined in terms of whether they can be used by the general public, including children and pregnant woman.
