Watanebe T, Morita M. In addition, it has been stated that gases which are relatively insoluble in blood increase rapidly toward equilibrium with the inhaled concentration and the less soluble in blood the faster the narcotic action of the gas Drummond The concentration-response curve appears to be very steep indicating that a large uncertainty factor is unnecessary.

Butane | C4H10 – PubChem
Several alkanes C 3 to C 7 were studied in this experiment and more severe effects were reported for hexane and heptanes, suggesting that if effects were observed with butane they would have been described more explicitly. It is difficult to calculate the dosage of butane being consumed by users so effects intosication vary between individuals. Case Reports In nonfatal cases, butane appears to have frequently affected the heart and brain.
Butane used in gas lighter refills consists of butane with small amounts of isobutane and propane. Although case reports of butane exposure indicate potential for cardiac sensitization analogous to propanethis end point has not been studied. Non Fluorinated Propellants and Solvents for Aerosols.
In another case of butane abuse, a swollen brain was observed in a year-old girl without a history of butane abuse Williams and Colewhile a CT head scan showed no abnormalities in a buutane male with a 3-year history of butane abuse Edwards and Wenstone Death during deliberate propane inhalation.
Intodication that were most often seriously affected in these cases were the brain and heart.
Butane is a gas at room temperature and atmospheric pressure. Surviving mice recovered within a few intoxiaction after exposure ended. 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 lungs per minute to body weight, which is approximately two-fold greater in mice.
Butane – Drug and Alcohol Information and Support in Ireland –
Results of lethality studies suggest that mice might be more sensitive than rats; mice had a shorter time to death and their 2-h LC 50 values were close to the 4-h LC 50 values in rats. Sign up to our eBulletin. Exposure concentrations were reported to be controlled by gas chromatography, but no information about the concentrations of butane tested or the duration of the postexposure observation period was provided.
There were some cerebral remnants lntoxication the thalamic regions, and the posterior fossa structures appeared to be preserved. A year-old boy who was known to inhale butane from a plastic bag had bilateral hemispheric infarcts Bauman et al. The results of microbial mutation test for forty-three industrial chemicals; pp.
The relative anesthetic activity of the butanes and pentanes; pp. It enters the blood supply and within seconds produces intoxication. The use of this study is hampered by the possibility that exposure concentration decreased during the study. AEGLs represent threshold exposure limits for the general public and haz applicable to emergency exposure periods ranging from 10 minutes min to 8 hours h.
Lithium hydride, LiH ionic metal hydride Beryllium hydride Left gas phase: Die Autoren sind der Ansicht, daR die MiRbildung durch eine intrauterine Anoxie hervorgerufen wurde, die wahrend der fetalen Hirnentwicklung aufgetreten ist.
Contaminants are not used in fragrance extraction and butane gasses can cause gas explosions in poorly ventilated areas if leaks go unnoticed and are ignited by spark or flame. Patty and Yant studied the warning properties of several alkanes, including butane. Animals recovered quickly and appeared normal after exposure ended. Downloads Download data is not yet available. The chemicals are soluble in body fat and pass rapidly to the brain and organs, so they take effect quickly. Four human subjects 3 male, 1 female; years of age were exposed to butane at ppm for 4 h.
Suicide by Inhalation of Suffocative Gas
An intraspecies uncertainty factor of 1 is ak adequate because the concentration-response curve for CNS-effects appears to be very steep; thus, interindividual variability will be relatively small. Los autores creen que la malformacidn fuk debida a la anoxia intrauterina que t w o lugar durante el desarrollo cerebral del feto. Help Center Find new research papers in:
