Dr. Medinsky and colleagues of the Chemical Industry Institute of Toxicology sought to determine how formate, a metabolite produced when methanol is broken down by the body, is formed and removed in monkeys after they have been exposed to methanol vapors. The investigators exposed female cynomolgus monkeys to environmentally relevant concentrations (10, 45, or 200 parts per million) of methanol vapors and to one high dose (900 ppm) for two hours.

Dr. Weiss and his colleagues at the University of Rochester School of Medicine and Dentistry examined the effects of prenatal and early postnatal inhalation of methanol on selected measures of neurobehavior in rats. The investigators conducted a controlled series of experiments in which they exposed pregnant rats and their newborn offspring to 4,500 parts per million (ppm) methanol by inhalation, and then submitted them to tests of behavioral function.

In this pilot study, Dr. Mary Cook and colleagues at the Midwest Research Institute explored how exposure to methanol vapor might affect the human nervous system. Methanol could be used as an alternative fuel, but it may lead to increased levels of methanol and formaldehyde in the atmosphere. The investigators exposed 12 young male volunteers to either filtered air or methanol vapor and assessed their response using 20 commonly used tests of sensory, behavioral, and reasoning performance before, during, and after each exposure.
