Gasoline is largely a mixture of hydrocarbons, although some may contain significant quantities of ethanol and some may contain small quantities of additives such as tertiarybutylmethyl ether as �anti-knock� agents to increase the octane rating. The hydrocarbons consist of a mixture of n-paraffins, naphthenes, olefins and aromatics. Naphthenes, olefins and aromatics increase the octane rating of the gasoline whereas the n-paraffins have the opposite effect. The aromatics consist mostly of a mixture of benzene, toluene and the xylenes. The benzene content is kept to a minimum (but is not negligible) due to its perceived toxicity. Originally lead tetraethyl was added as an anti-knock agent but is now rarely used and is prohibited in most countries due to its toxicity. Gasoline is usually analyzed by gas chromatography using a capillary column coated with a suitable dispersive stationary phase and is temperature programmed. The composition of a gasoline can vary significantly depending on the source of the crude oil, the method employed for processing and its intended use.

The Material Safety Data Sheet for unleaded gasoline shows at least fifteen hazardous chemicals occurring in various amounts. These include benzene (up to 5% by volume), toluene (up to 35% by volume), naphthalene (up to 1% by volume), trimethylbenzene (up to 7% by volume), MTBE (up to 18% by volume, in some states) and about ten others.

DO STANDARDS EXIST FOR REGULATING GASOLINE?

Water: Although no standard exists for gasoline in drinking water, there are standards for some of the chemicals that make up gasoline’s mixture. The standard for benzene (2% of the gasoline mixture) is 5 parts per billion (ppb), ethyl benzene is 700 ppb, toluene is 1.0 part per million (ppm), and xylene is 10 ppm. We suggest you stop drinking or cooking with water containing any chemical above the standard, if you can smell a gasoline odor or see a oily sheen. If the chemicals occur at very high levels in your drinking water, you should avoid washing, bathing or using the water for other purposes.

Wanna tell me again that gasoline doesn't contain those chemicals?
