It has now been more than 20 years since the establishment of the MHLW Guidelines (1997-2002) and the revised Building Code (2003) came into force, and there has been a dramatic improvement in indoor air quality since that time. In addition, guideline valnes on the concentrations of three substances were revised and strengthened in the MHLW guidelines in April 2019. The issue of shifting to alternative substances to avoid these regulations is an ongoing challenge that needs to be addressed.
Possible pollutants that will continue to be discussed include benzene, 2E1H, texanol, TXIB, terpenes such as pinene and limonene, which are components emitted from natural woods, plasticizers and flame retardants, insect repellents and insecticides, fragrance components in air fresheners, deodorants, and detergents.
It is impossible to live without contacting chemicals in modern society. While not all chemicals are harmful, we need to deal with them rationally, making efforts to keep concentrations as low as possible, and to live with them wisely.
