New EPA Gas Mixtures Ensure Accuracy in Hazardous Waste Testing.
A collection of hazardous organic gases at very low levels has been created by the EPA for testing purposes. The project aims to provide accurate gas mixtures for performance audits, verify manufacturer's analyses, assess gas stability over time, and develop new audit materials. The repository includes three mixtures with different organic compounds. So far, 41 performance audits have been started, with 35 completed. The results of these audits and information on experimental procedures and gas stability are detailed in the report.
