Industrial Solvents
Industrial solvents are themost likelyVOCs tobe abused.
Industrial solvents are available inpurified formor as solvents in
manyhouseholdproducts. Toluene is themost commonly abused
industrial solvent and is used inmanyproducts such as paints or
glues (Figure 4).

PetroleumHydrocarbons
Distilledpetroleum fractions are used as carrier solvents formany
commercial products. Distilled fractions, likemineral spirits, are
used inproducts like pesticides, herbicides, paints, lacquers, thin-
ners, andhousehold cleaningproducts. Inhalation, ingestionor
adsorption through the skin canproduce detectable concentrations
of a varietyof individual hydrocarbons (Figure 5).
