The effects of hydrocarbons found in gasoline when the mixture was analyzed using gas chromatography

In an emergency, an equivalent amount of any alcoholic drink may be administered orally. Prolonged ethanol administration may cause hypoglycaemia, especially in children, and frequent blood glucose determinations are mandatory Goldfrank et al.

If haemodialysis is started, the ethanol infusion should be increased as detailed in Section The same dose may be administered orally. No side effects have been reported with this dosage regimen and effectiveness is clearly demonstrated Brent et al. If dialysis is performed, the dose of fomepizole must be increased as fomepizole is eliminated at the same rate as urea.

Ethanol is more likely to cause hypoglycaemia in children Bayer et al. Ethanol should be administered as soon as possible after exposure, ideally before the onset of clinical and laboratory findings that indicate extensive metabolism of methanol.

Continuous and accurate control of ethanol levels is rarely achieved even in intensive care units, especially over long time periods Litovitz, ; Osterloh et al. In patients who have a history of severe exposure and ingestion of near-lethal quantities, and in patients who have high methanol blood levels, early haemodialysis is mandatory to reduce the toxic burden of the body rapidly.

In advanced stages, or in cases where there have been repeated exposures to low doses or concentrations of methanol, ethanol is of doubtful value.

When laboratory findings demonstrate the absence of unchanged methanol in the body and the accumulation of toxic metabolites very low or absent methanol in the blood, high levels of formate in blood and urineethanol is probably useless. However, haemodialysis can still be useful, since both methanol and formate are dialysable substances.

Diseases Associated With Benzene Exposure:

Folic acid or related folates Ethanol and 4-MP prolong the elimination of methanol, inhibiting its metabolism. A more effective treatment would be to increase the elimination of the toxic metabolites formic acid by increasing their metabolism.

Primates are sensitive to methanol poisoning because they do not oxidize formate as readily as do rodents due to a relative deficiency in the function of the folate system Eells et al.

Folic acid treatment in monkeys, even if started as late as 10 h after methanol, prevents formate accumulation Noker et al. In a recent study, four methanol-poisoned patients were treated with intravenous folate and ethanol, combined in two cases with haemodialysis Osterloh et al.

An apparent reduction in formate half-life was obtained. Folate treatment is safe and seems advisable since many alcoholics are folate deficient Osterloh et al.

Methanol then became cheaper than ethanol resulting in its use for the adulteration of wine. In 2 days 12 to 13 March three cases with striking clinical features in common were referred to the Milan Poison Unit: Admitted to hospital 11 to the Milano P.Toluene Sources, Testing, Air Purification, and Health Information Toluene is a common solvent found in many products throughout the average home, such as glues, octane boosters, inks, dyes, paints, gasoline, and cigarette smoke.

A second sample analyzed by gas chromatography/mass spectrometry, analysis done by Elmar Lackner yielded a similar result, 65% phenanthrene and 35% fluorene, C 13 H A third sample was a complex mixture of hydrocarbons and could not be attributed to any specific mineral or organic compound.

Comparative analyses of pollutant emission levels from a spark ignition (SI) engine were performed on mixtures of gasoline with potential liquid fuel extenders including biomass derived α-methyltetrahydrofuran (MTHF).

The aromatic hydrocarbons in finished gasoline, gasoline blending feedstock, and straight-run naphtha were quan- titatively analyzed using an Agilent gas chromato-.

Chromatography is the science of separation which uses a diverse group of methods to separate closely related components of complex mixtures. During gas chromatographic separation, the sample is transported via an inert gas called the mobile phase.
