- BTEX
BTEX is an acronym that stands for
benzene ,toluene ,ethylbenzene , andxylene s. These compounds are some of thevolatile organic compound s (VOCs) found inpetroleum derivatives such aspetrol (gasoline).Toluene ,ethylbenzene , andxylene s have harmful effects on the central nervous system.BTEX compounds are notorious due to the
contamination ofsoil andgroundwater with these compounds. This typically occurs near petroleum andnatural gas production sites, and petrol stations and other areas with Underground Storage Tanks (USTs) or Above-ground Storage Tanks (ASTs) containing gasoline or other petroleum-related products.The amount of 'Total BTEX', the
sum of the concentrations of each of the constituents of BTEX, is sometimes used to aid in assessing the relative risk or seriousness at contaminated locations and the need of remediation of such sites.Naphthalene may be included in Total BTEX analysis yielding results referred to as BTEXN. In the same way,styrene is sometimes added, making it BTEXS.
