1 : Halogenated Volatile Organic Compounds from the Use of Chlorine-Bleach-Containing Household Products MUSTAFA ODABASI Department of Environmental Engineering, Faculty of Engineering, Dokuz Eylul University, Kaynaklar Campus, 35160 Buca, Izmir, Turkey e-mail: mustafa.odabasi@deu.edu.tr, phone: 90-232-412 7122 fax: 90-232-412 7080
2 : Introduction A number of commonly used household cleaning products (bleaches, mildew stain removers, toilet cleaners, cleaning sprays, gels, and scouring powders) contain sodium hypochlorite that is often accompanied by many other chemicals (e.g., surfactants and fragrances). Mixing bleach with ammonia-based cleaners results in formation of chloramines while mixing it with an acid-based cleaner will cause chlorine gas release. Therefore, the main concern associated with the use of chlorine-bleach-containing cleaning-products has been mixing them with other cleaning products that can generate hazardous fumes. Previous research has raised two very important questions: (1) Do chlorinated byproducts form when bleach containing cleaning products react with organic matter present on dirty surfaces? (2) Do the hypochlorite and, the organic product ingredients (i.e., surfactants, fragrances, and other compounds) react to generate chlorinated byproducts?
3 : Objectives To investigate the presence of halogenated VOCs in different chlorine bleach containing household products (in pure and diluted forms) and their emission characteristics To determine the indoor air halogenated VOC concentrations resulting from the use of selected household products.
