Comparison of Methods for Sampling Bacteria at Solid Waste Processing Facilities

摘要

The report is an assessment of the field sampling methodologies used to measure concentrations of airborne bacteria and viruses in and around waste handling and processing facilities. The sampling methods are discussed as well as the problems encountered and subsequent changes made to improve the methods. Comparisons are also made to preliminary recommendations from ASTM subcommittee E-38.07 on Health and Safety Aspects of Resource Recovery plants. The results showed air filte methods such as a Hi-Vol sampler are not generally recommended because of dessication effects of the air stream passing over the filter. AGI-30 impingers and Andersen agar plate impactors are preferred methods. The complete tests are fully reported in the final report, Assessment of Bacteria and Virus Emissions at a Refuse Derived Fuel Plant and Other Waste Handling Facilities, EPA 600/2-78-152, U.S. Environmental Protection Agency, August 1978.
