1. Introduction. In order to interpret, evaluate the risk and make decisions about potential hazardous effects of petroleum hydrocarbons and ensure the appropriate protection of the environment, it is very important to have a sound understanding of the toxicology, analytical science, environmental fate and behaviour, risk and technological implications of petroleum hydrocarbons. A high-performance liquid chromatography gradient scheme has been used to separate the aromatic hydrocarbons in the aqueous effluents of a coal gasification process. Samples of raw water, activated sludge, and activated sludge plus carbon-treated effluents were evaluated.
This test method covers the determination of fluorocarbon-extractable substances as an estimation of the combined oil and grease and the petroleum hydrocarbon contents of a sample of water or waste water in the range from to mg/L. It is the user's responsibility to assume the validity of the standard for untested types of water.

Precautions No known solvent will dissolve effectively only oil and grease. Solvent removal results in the loss of short chain hydrocarbon and simple aromatic compound by volatilisation, and heavier residual of some effluents may contain significant portion of material that are not extracted with the solvent.

transformations of petroleum hydrocarbons in the environment. The methods generally employed to measure the TOG in the oil industry are gravimetry and infrared spectrometry [6, 7].
Gravimetric methods, such as Method and Standard Method B from the U.S. Environmental Protection Agency (EPA), involve liquid-liquid extraction. infrared and mass spectrometric, the latter types being necessary to achieve speciation of Formerly, the idea of total hydrocarbon determination in soil was seen as providing a satisfactory tool for assessing contaminated sites.

Concawe. A direct aqueous supercritical fluid extraction (SFE) system was developed which can be directly interfaced to an infrared spectrometer for the determination of oil in water.
The technique is designed to provide an environmentally clean, automated alternative to established IR methods for oil in water analysis. EPA promulgated the Oil and Gas Extraction Effluent Guidelines and Standards (40 CFR Part ) inand amended the regulations in, and The regulations cover wastewater discharges from field exploration, drilling, production, well treatment and well completion activities.
Common oil in water analysis reference methods include infrared, gravimetric and GC-FID based, each has its own advantages and disadvantages. To get a good oil in water result, in addition to having a good analysis method, sampling and sample handling is equally important, as measurement can only produce a result as good as the sample can provide.

Based on these aspects, the main objective and contri-bution of this work is to purpose a new process for treat-ment of contamination of aqueous sources by hydrocarbons from petroleum, using sugarcane bagasse as bioadsorbent.
Polycyclic aromatic hydrocarbons (PAHs) are major organic pollutants in the environment, which are toxic to humans and biota, given their carcinogenic, mutagenic and teratogenic nature.
In this chapter, we carried out an overview of the sources and toxicity of PAHs, their common analytical methods of determination in the water and sediment samples, and.
