Determining Total Petroleum Hydrocarbons in Soil

Proceedings of SPE Annual Technical Conference and Exhibition, 1993
Abstract Many state agencies, using an infrared analysis [IR], establish total petroleum hydrocarbon (TPH) levels above which soils are considered contaminated. As a result, clean closure of contaminated areas are prohibited and, in some cases, Deed Recordation required. In many instances, a fraction of the hydrocarbon observed using the

Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge

World Review of Science, Technology and Sustainable Development, 2004
Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in ...

An evaluation of field total petroleum hydrocarbon (TPH) systems

Journal of Hazardous Materials, 2001
An evaluation of several field kits and petroleum hydrocarbon measuring systems was conducted. The field kits were the immunoassay based EnviroGard petroleum fuels in soil test kit (EnviroGard, Millipore Canada, Mississauga, Ont., Canada), the turbidimetric based PetroFlag hydrocarbon test kit for soil (Dexsil, Hamden, CT, USA), a DR/2000 field kit ...

Bioavailability of Total Petroleum Hydrocarbons

2019
There is a fundamental need to understand and possibly quantify the bioavailable fraction of total petroleum hydrocarbons (TPHs) present in the environment. Bioavailability can be defined as the amount of a pollutant that can be readily taken up by microorganisms for biodegradation.

Rapid Field Analytical Methods for Total Petroleum Hydrocarbons

SPE Asia Pacific Health, Safety, Security, Environment and Social Responsibility Conference, 2017
Abstract Total Petroleum Hydrocarbons (TPH) in soil is often measured to determine if soils have been impacted by crude oil. PT. Chevron Pacific Indonesia (CPI) operates several oil fields in Sumatra and samples soil for TPH content for remediation-related work. Traditional laboratory methods used to analyze for TPH in soil require three

Spatial Inhomogeneity of Total Petroleum Hydrocarbons in the Caucasus Coastal Seawater

Russian Meteorology and Hydrology, 2023
Long-term data on total petroleum hydrocarbons (TPHs) at individual stations of the state seawater monitoring system in the areas of Anapa, Novorossiysk, Gelendzhik, and Tuapse during 1996-2019 are analyzed. Parameters of the long-term regime at the stations are compared, and the significance of the detected differences is assessed using statistical ...

Ecological Impacts of Total Petroleum Hydrocarbons

2019
Contamination of soil and aquatic ecosystems by petroleum hydrocarbons (PHs) is a serious global issue. The total petroleum hydrocarbons (TPHs) that originate from the distillates of crude oil in the form of diesel, gasoline, lubricating oil, and other typical PHs received much attention globally as contaminants since they are highly toxic, mutagenic ...

An Overview of Total Petroleum Hydrocarbons

2019
Total petroleum hydrocarbons (TPHs) are one of the common contaminants in the environment. They include a broad family of several hundred hydrocarbon compounds that originally come from crude oil which is used to make petroleum products. The widespread use of crude oil and other petroleum products for transportation, heating, and industry leads to the ...

Biodegradation of Total Petroleum Hydrocarbons from Oily Sludge

Bioremediation Journal, 2011
ABSTRACT The present study concerns the biotreatment of oily sludge of petroleum refineries. Experiments were performed to assess the degradation potential of the microbial species present in the oily sludge through augmentation, and using the augmented microbial inoculums to treat oily sludge in a slurry form containing mineral medium and water.
