Spletof field methods for the determination of TPH in soils. This was an ambitious project that involved the establishment of a TPH definition and the development of a reference se- lected for -846 Method 9074 (Lynn et al., 2002; 1996a). At present, a wide variety of specific and non- specific methods are used for analysis of TPH. 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 other petroleum products, it is not practical to measure each one separately. However, it is useful to measure the total amount of T…
