Vitreous humor is strongly recommended as a body fluid for determination of ethanol in postmortem toxicology to help establish whether the deceased had consumed ethanol before death. Oral LD 50 s in rats, mice, guinea pigs, rabbits, and dogs range from 6 to 18 g kg 1.Inhalation LC 50 s range from 12 000 to 50 000 ppm in studies of mice, guinea pigs, and rats. Use alcohol-free swabs, peroxide, or betadine Formic acid (undissociated) exists in an equilibrium with formate (dissociated). The acute oral, inhalation, and dermal toxicities of ethanol in animals are low. The BAC is dependent on rates of absorption, distribution, and elimination, which are influenced mostly by the dose of ethanol ingested and rate of consumption. In places without access to fomepizole, ethanol given as an infusion or orally can be used to block ADH.
