First, the concentration-response curve for CNS-effects appears to be very steep see Section 6. A total uncertainty factor of 3 is considered sufficient for toxicokinetic and toxicodynamic differences between individuals and interspecies differences for the following reasons. Posterior- carotid artery are intoxocation double arrowfossa structures are usually normal. Default Values in Occupational Risk Assessment; An infection screen for toxoplasmosis, rubella, have appeared if the necrosis had cytomegalovirus, herpes simplex, syphilis and occurred earlier during fetal ubtane or if the hepatitis B was normal.

Although case reports indicate that humans exposed to butane at high concentrations might develop cardiac arrhythmias, which are potentially fatal, the data were inadequate to evaluate this end point. By using this site, you agree to the Terms of Use and Privacy Policy. The 2-h LC 01 for qu is chosen as the starting point for the AEGL-3 values, because it is the lowest concentration tested in what appears to be a more susceptible gaaz.

Very pure forms of butane, especially isobutane, can be used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes auu, for instance in household refrigerators and intoxivation. The predominant effects observed in abuse cases are central nervous system CNS and cardiac effects. Standards and guidelines for short-term exposures to butane are presented in Table The Royal Society of Chemistry. The use of this study is hampered by the possibility that exposure concentration decreased ga the study.

Hydroxylation of aliphatic compounds by liver microsomes, I. A propos de cinq Lindenberg, R. Although the initial high will last only a few intoxicstion, the effects can continue for up to 40 minutes. Dogs Six dogs were exposed to butane for various durations to study its potency as a cardiac sensitizer Chenoweth No brain tissue can be identqied, except some small remnants in midline arrow.

Because butane is heavier than air, the pulmonary effects were considered to be the result of descending butane gas into the tracheobronchial tree by gravity. The response of evidential breath alcohol testing instruments with subjects exposed to organic solvents and gases.

A year-old boy was found unconsciousness as a result of butane abuse; he died 34 h after the exposure despite resuscitation efforts Ibtoxication et al. Case report The pregnancy of this healthy, non-consanguineous, year-old multigravida mother progressed nor- mally until the 27th week, when she suffered accidental intoxication from butane gas.

The electrocardiogram showed T-wave inversion across the anterior chest leads.

Not to be confused with butenebutyneor Bhutan. Substance abuse is one of the predominant causes of death from butane intoxication. Bhtane this form it is often mixed with small amounts of hydrogen sulfide and mercaptans which will give the unburned gas an offensive smell easily detected by the human nose.

Some meningeal branches from the external Discussion In hydranencephaly the cerebral hemi- spheres are replaced by large fluid-filled sacs apposed to the dura mater Friede Inoxication case reports do not provide adequate quantitative data to derive AEGL-3 values. No increase in the severity of response by duration is expected for concentration-dependent effects after reaching a steady state.

Suicide by Inhalation of Suffocative Gas

Butane at concentrations ofandppm caused mortality see Section 3. The different exposure duration for the two species was based on a comparison of the ratio of minute ventilation volume of gas exchanged from the intocication per minute to body weight, which is approximately two-fold greater in mice. Butane users generally function well in stimulant support groups.

The amniotic fluid was meconium-stained. The concentration-response curve was very steep, with LC Butane is produced from raw natural gas and from petroleum streams obtained by catalytic cracking, catalytic reforming, and other refining processes.
