Inhalants A variety of psychoactive substances have been inhaled as gases or volatile liquids. Many popular commercial preparations, such as paint thinners and cleaning fluids, are mixtru es of volatile substances making it difficult to be speciflc about their various effects. 

Volatile substances. Volatile substances are chemicals that keep the paints fluid enough to be applied easily, and that subsequently evaporate during drying. In some cases, these volatile substances actually dissolve the binders and other chemicals so that the paint is nearly a uniform liquid. Modem paints actually contain tiny solid binder particles that are suspended in the volatile substances. These particles become a continuous coating as the volatile substances evaporate. 

Despite these numerous advantages, mass spectrometry has often been used more as an auxiliary, rather than a primary, identification method for additives in polymers, paints, coatings, etc. Nevertheless, mass spectrometry can be used for direct determination of the composition of unknown admixtures. More difficult is the MS examination of substances of low volatility, as the sample has to be introduced in the gas phase. This requires volatilisation, which often leads to fragmentation. 

The focus is on a small and medium enterprise (SME) for which the use of chemicals is a minor part of the entire production chain. The SME uses painting guns for painting and coating operations of metals. These guns are cleaned with chemical substances, i.e. low volatile organic compounds (VOCs). 

A solvent is a substance that can dissolve another substance, and a volatile solvent is a liquid that vaporizes at room temperature. Volatile solvents include adhesives such as airplane glue and rubber cement aerosols such as spray paint, hair spray, and air freshener solvents such as nail polish remover, paint remover, and lighter fluid and cleaners such as dry cleaning fluid, spot remover, and degreasers. 

The pulmonary system is the site of entry for numerous toxicants. Examples of toxic substances inhaled by human lungs include fly ash and ozone from polluted atmospheres, vapors of volatile chemicals used in the workplace, tobacco smoke, radioactive radon gas, and vapors from paints, varnishes, and synthetic materials used for building construction.

Chloroform is a volatile, sweet-tasting liqnid that was nsed for many years as an anesthetic. However, because of its toxicity (it can severely damage the liver, kidneys, and heart) it has been replaced by other componnds. Carbon tetrachloride, also a toxic substance, serves as a cleaning liquid, for it removes grease stains from clothing. Methylene chloride is nsed as a solvent to decaffeinate coffee and as a paint remover. 

Industrial solvents Solvents and a wide range of volatile compounds are present in commercial products such as gasoline, paint thinners, aerosol propellants, glues, rubber cements, and shoe polish. Because of their ready availability, these substances are most frequently abused by children in early adolescence. Active ingredients that have been identified include benzene, hexane, methylethylketone, toluene, and trichloroethylene. Many of these are toxic to the Uver, kidneys, lungs, bone marrow, and peripheral nerves and cause brain damage in animals.
