SVOCs differ from VOCs in that they generally have a vapor pressure less than 5.35 bar (making them less volatile) and require chemical extration prior to analysis. As a group, SVOCs have the same properties and behaviors of VOCs. Contaminant flow occurs through the same mechanisms as described for VOCs. While the degree of volatilization from SVOCs is much less than for VOCs, this process still occurs.
The following is a list of common non-halogenated SVOCs:
Benzidine Benzoic acid Benzyl alcohol n-Bis(2-ethylhexyl)phthalate Butyl benzyl phthalate Dibenzofuran Di-n-butyl phthalate Di-n-octyl phthalate Diethyl phthalate Dimethyl phthalate 4,6-Dinitro-2-methylphenol 2,4-Dinitrophenol 1,2-Diphenylhydrazine Isophorone 2-Nitroaniline 3-Nitroaniline 4-Nitroaniline 2-Nitrophenol 4-Nitrophenol n-Nitrosodimethylamine n-Nitrosodiphenylamine n-Nitrosodi-n-propylamine Phenyl naphthalene
