The three most quoted oil products are North America's West Texas Intermediate crude (WTI), North Sea Brent Crude, and the UAE Dubai Crude, and their pricing is used as a barometer for the entire petroleum industry, although, in total, there are 46 key oil exporting countries. Brent Crude is typically priced at about $2 over the WTI Spot price ...
Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
Many compounds found in oil are highly toxic and can cause cancer (carcinogenic) as well as other diseases. [23] Studies in Taiwan link proximity to oil refineries to premature births. [26] Crude oil and petroleum distillates cause birth defects. [27] Benzene is present in both crude oil and gasoline and is known to cause leukaemia in humans. [28]
Since sour crude is more common than sweet crude in the U.S. part of the Gulf of Mexico, Platts has come out in March 2009 with a new sour crude benchmark called "Americas Crude Marker (ACM)".

Oil pollution toxicity to marine fish has been observed from oil spills such as the Exxon Valdez disaster, and from nonpoint sources, such as surface runoff, which is the largest source of oil pollution in marine waters. Crude oil entering waterways from spills or runoff contain polycyclic aromatic hydrocarbons (PAHs), the most toxic components ...

Aliphatic kerosene is a type of kerosene which has a low aromatic hydrocarbon content, the aromatic content of crude oil varies greatly from oil field to oil field. However by solvent extraction it is possible to separate aromatic hydrocarbons from aliphatic (alkane) hydrocarbons.
