- Abstract
- Transparent polycarbonate and acrylic plastics were exposed to air, nitrogen, and oxygen in glass containers at 25 C. Carbon Monoxide was release from both types of plastic into the gas phase. The amount CO released from a given plastic sample was similar in the presence of air, nitrogen, or oxygen but was markedly increased following previous exposure to CO. The data indicate that CO release from these materials is due to the slow removal of gas dissolved in the plastic and not to their reaction with molecular oxygen. This property of CO exchange between gas and plastic is important when such materials are used in animal studies of CO production, distribution, or total body hemoglobin estimations involving CO.
