The EPA requires that spills or accidental releases into the environment of 10 pounds (4.5 kg) or more of benzene be reported. The U.S. Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit of 1 part of benzene per million parts of air (1 ppm) in the workplace during an 8-hour workday, 40-hour workweek.
Global consumption of benzene, estimated at more than 40,000,000 tons in 2010, showed an unprecedented growth of more than 3,000,000 tons from the level seen in 2009. Likewise, the para-xylene consumption showed unprecedented growth in 2010, growing by 2,800,000 tons, a full ten percent growth from 2009.

The density of each isomer is around 0.87 g/mL (7.3 lb/US gal; 8.7 lb/imp gal) and thus is less dense than water. The odor of xylene is detectable at concentrations as low as 0.08 to 3.7 ppm (parts of xylene per million parts of air) and can be tasted in water at 0.53 to 1.8 ppm.
The main petroleum component used in blending avgas is alkylate, which is a mixture of various isooctanes. Some refineries also use reformate.All grades of avgas that meet CAN 2–3 [further explanation needed], 25-M82 [further explanation needed] have a density of 6.01 pounds per US gallon (720 g/L) at 15 °C (59 °F).
Ethylbenzene is produced on a large scale by combining benzene and ethene in an acid-catalyzed chemical reaction: C 6 H 6 + C 2 H 4 → C 6 H 5 CH 2 CH 3. In 2012, more than 99% of ethylbenzene was produced in this way. [citation needed] Small amounts of ethylbenzene are recovered from the mix of xylenes by superfractioning, an extension of the ...
To test these two aircraft, the USAF has ordered 281,000 US gal (1,060,000 L) of FT fuel. The USAF intends to test and certify every airframe in its inventory to use the fuel by 2011. They will also supply over 9,000 US gal (34,000 L; 7,500 imp gal) to NASA for testing in various aircraft and engines. [needs update]
