never underestimate the powers of VOC.
VOCs are a mix of chemical compounds:
Chlorofluorocarbons CFCs: a non-toxic mix of chemicals with atoms containing hydrogen, carbon, fluorine, and chlorine that are used for refrigeration, packing, and most aerosol sprays. This compound is a known ozone depleter and is being phased out.
Formaldehyde: a naturally occurring compound that is used mainly in paper and wood products or for preservation. Some people have great sensitivity to the smell of this compound.
Toluene: a solvent used to make adhesives, paint thinners, gasoline, and rubber.
Benzene: an organic chemical compound used in detergents, plastics, and dyes. Benzene is naturally released through fires and volcanoes. It is also responsible for the pungent smell of gasoline.
Methylene: a chemical compound used in paint stripping, oven cleaners, and foam production.
Naphthalene: a chemical compound used in mothballs, plastics, insecticides, and synthetic fibers in foams.
Trichloroethane: an organic compound used as a solvent. It usually helps make adhesives, inks, and oil cleaners for metal car parts.
Perfluorocarbon PFCs: a mix of non-toxic organic compounds that contain carbon and fluorine that are used in solvents and oxygen tanks.
Good luck finding the thread where that might be relevant.
