Indoor Air Chemistry: Cleaing Agents, Ozone and Toxic Air Contaminants
When cleaning products and air fresheners are used indoors, occupants are exposed to airborne chemicals, potentially leading to health risks. Indoor air pollutant exposures owing to cleaning product and air freshener use depend on emissions from products, dynamic behavior of chemical species, and human factors. A series of experiments was conducted to investigate volatile organic compound emissions, concentrations, and reactive chemistry associated with the household use of cleaning products and air fresheners. Research focused on two common classes of ingredients in cleaning products and air fresheners: ethylene-based glycol ethers, which are classified as toxic air contaminants, and terpenes, which react rapidly with ozone. A shelf-survey of retail outlets led to the selection of 21 products whose chemical composition was characterized.
