Bioavailability of Total Petroleum Hydrocarbons
2019There 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.

Ecological Impacts of Total Petroleum Hydrocarbons
2019Contamination 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 ...

Strain-Free Total Resonant Sextet Benzenoid Hydrocarbons
Polycyclic Aromatic Compounds, 1991Abstract The importance of strain-free (total) resonant sextet benzenoid hydrocarbons is pointed out. The first computer-aided generation and enumeration of such systems is reported, and the data represent substantial supplements to the previous numbers of strain-free resonant sextet benzenoid isomers.

An Overview of Total Petroleum Hydrocarbons
2019Total 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 ...

Determination of Total Hydrocarbons in Water
International Journal of Environmental Analytical Chemistry, 1982Abstract It is important to the oil refining industry to obtain accurate and reliable data on the levels of hydrocarbons in aqueous discharges. However, considerable difficulties are presented in placing data from different locations on a comparable basis, because of the number and diversity of procedures used.

Total Cross Sections of Hydrocarbons and Tissue
Nuclear Science and Engineering, 1961The total neutron cross sections of several organic materials are measured in the energy region 0.0I5 ev < E < 0.2 ev. The data are to be used in the application of the Neutron cross sections were studied for formic, acetic, propionic, and butyric acids; ethyl, propyl, and butyl alcohols; methyl-ethyl ketone; and human muscle, brain, and bone tissues ...

An Evaluation of Automobile Total Hydrocarbon Emissions
SAE Technical Paper Series, 1966<div class="htmlview paragraph">Practical and simple procedures have been developed to reliably estimate the quantity and reactivity of automobile carburetor and gasoline tank evaporative emissions. These methods along with previously developed exhaust hydrocarbon emission procedures have been used to determine the effects of fuel volatility on ...

An evaluation of field total petroleum hydrocarbon (TPH) systems
Journal of Hazardous Materials, 2001An 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 ...

Analysis of polycyclic aromatic hydrocarbons in UK total diets
Food and Chemical Toxicology, 1983Analysis of UK total-diet samples for polycyclic aromatic hydrocarbons was carried out using a simplified sample clean-up and a high-performance liquid chromatography dual fluorescence detector system. The results indicate that cereals and oils/fats contribute the major part (approximately one third each) of the polycyclic aromatic hydrocarbons in ...

Polycyclic aromatic hydrocarbons in Dutch total diet samples (1984–1986)
Food and Chemical Toxicology, 1990Over a period of 2.5 yr, 221 different food items of a 'market basket' of 18-yr-old males were purchased every 3 months. In total, 10 market baskets were collected. The foodstuffs were prepared by normal methods and combined into 23 commodity groups. Homogenates were prepared from each commodity group, followed by analysis for 17 different polycyclic ...
