Petroleum Hydrocarbons Eurofins USA

Total petroleum hydrocarbons (TPH) are a large family of several hundred chemical compounds that originate from crude oil (mainly hydrogen and carbon). Because TPH can be divided into groups (fractions) of petroleum hydrocarbons that act alike, it is not practical to measure each chemical separately. Rather, the total TPH

Removal of Total Petroleum Hydrocarbons from Contaminated

Total petroleum hydrocarbons (TPH) are composed of a complex mixture of saturated hydrocarbons (primarily paraffins, 60–80%) and aromatic hydrocarbons (20–40%) [4,5]. Most TPH contaminants are biodegradable over time, but bioremediation has poor bioavailability and a long degradation period because of the inefficient air

The following sections present an overview of releases to the environment (5.2), fate and transport (5.3), and levels found in the environment (5.4).

Risk-Based Evaluation of Total Petroleum Hydrocarbons in

Petroleum-contaminated soil and groundwater are traditionally assessed in terms of Total Petroleum Hydrocarbons (TPH) and targeted, individual compounds such as benzene, toluene, ethylbenzene, xylenes and naphthalene (BTEXN). The buildup of methane vapors at petroleum-release sites can also pose potential fire and explosion hazards.

Total petroleum hydrocarbon

Total petroleum hydrocarbons ( TPH) is a term used for any mixture of hydrocarbons that are found in crude oil. There are several hundred of these compounds, but not all occur in any one sample. Crude oil is used to make petroleum products, which can contaminate the environment. Because there are so many different chemicals in crude oil and in
