A steep concentration-response curve for mortality was observed in mice and rats; the LC Vol 10 No 3Case Reports. The AEGL-1 values for butane are based on observations in a study with volunteers on the warning properties of short exposures to butane Patty ua Yant Although the AEGL values represent threshold concentrations for the general public, including susceptible subpopulations, such as infants, children, the elderly, persons with asthma, and those with other illnesses, it is recognized that individuals, subject to idiosyncratic responses, could experience the effects described at concentrations below the corresponding AEGL.
Fatal propaneputane poisoning [in German] pp. In another case of butane abuse, a swollen brain was observed in a year-old girl without a history of butane abuse Williams and Coleintoxicaiton a CT head scan showed no abnormalities in a year-old male with a 3-year history of butane abuse Edwards and Wenstone The kidneys were underdeveloped, and the heart showed bugane foci of butan in the subendocardial myocardium.
