Trifluoroiodomethane (CF3I) and 1,1,2,2,3,3,3-heptafluoro-1-iodopropane (C3F7I) have been considered as replacement candidates for halon fire suppressants due to their excellent fire extinguishant capabilities and low ozone depletion potential compar

Human exposure to halons and halon replacement chemicals is often regulated on the basis of cardiac sensitization potential. The dose-response data obtained from animal testing are used to determine the no observable adverse effect level (NOAEL) and

Groups of 10 male Hartley guinea pigs were exposed to 3.0, 2.0, 1.0, or 0.1% (v/v) 1,1-Dichloro-2,2,2-trifluoroethane (HCFC-123) or 1.0% (v/v) halothane by inhalation for 4 hr. A sixth group of 10 guinea pigs received only air. All animals were sacri

The hydraulic fluid oil polychlorotrifluoroethylene (PCTFE) is hepato- and nephrotoxic in the rat. Male Fischer 344 rats were exposed to PCTFE either for a single 6-hr exposure (0.5 or 0.25 mg/liter) or daily 5 days/week, 6 hr/day, for 13 weeks (0.5,

Biotransformation is often a determinant of pharmacokinetic behavior and toxicity. While the liver is usually the quantitatively most significant site, metabolism in other tissues may cause nonhepatic toxicity and also may affect the pharmacokinetic

Personal protective equipment often is used to prevent exposure to volatile toxicants. The effectiveness of such equipment can be evaluated by (1) measuring the postexpo-sure concentration of toxicant in expired breath and (2) using a physiologically

The goal of this study was to develop a human physiologically based pharmacokinetic (PBPK) model for the chemical HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane) and its major metabolite, trifluoroacetic acid (TFA). No human kinetic data for HCFC-123 a

An international consensus on the need to reduce the use of chlorofluorocarbons (CFCs) and other ozone-depleting gases such as the halons led to the adoptions of the 1987 Montreal Protocol and Title VI of the 1990 Clean Air Act Amendments, “Protect
