above. In addition to TPH, certain individual hydrocarbon constituents that are well characterized toxicologically (such as benzene) should be evaluated individually. These can be subtracted from the TPH measurements as described in Section 4.0. The evaluation of potential risks and hazards associated with exposure to TPH presents many challenges.

Tryptophan (TPH) is an essential amino acid found primarily in proteinaceous food such as milk, tuna, turkey, oats, cheese, nuts, and seeds [1,2]. TPH availability is thus largely dependent on dietary intake. Several factors influence circulating TPH levels, including cultural and geographic dietary practices, stress, and physical activity [3,4].

TPH is defined as the measurable amount of petroleum-based hydrocarbon in an environmental media. It is, thus, dependent on analysis of the medium in which it is found (Gustafson 1997). Since it is a measured, gross quantity without identification of its constituents, the TPH "value" still represents a mixture. Thus,
