They generate waste problems even before you buy them. Return to top of Household Hazardous Materials Paint Leftover oil or solvent-based paint is a hazardous waste. Toxic, dangerous chemicals used in the production of oil-based paint can pose serious threats to human health and the natural environment if handled or disposed of improperly. A Johns Hopkins University study found 300 toxic chemicals and 150 carcinogens that may be present in paint. Resins that cover the surface may contain ethylene, which may cause headaches, dizziness and loss of consciousness.
Ethylene also is flammable and can be toxic to aquatic wildlife.
Urethane alkyds, which cause nausea, vomiting, and drowsiness, also may be present. Solvents that keep the resin liquefied contain aromatic hydrocarbons such as mineral spirits and toluene. Mineral spirits can be a skin, eye, nose, throat and lung irritant, as well as flammable. Very high air concentration may cause unconsciousness and death. Toluene may irritate the eyes, respiratory tract and skin.
