Description:
The report discusses part of a Phase I carpet bioresponse study sponsored by EPA. he study evaluated emissions from carpet samples that had previously been reported to show toxic effects on experimental mice. he report describes the major findings of only the chemical characterization work conducted at the Indoor Source Characterization Laboratory of EPA's Air and Energy Engineering Research Laboratory. ll other results (animal testing, microbial testing, chemical analysis by sample extraction, and pesticide analysis) are reported separately. he experimental system used in this study, developed by Anderson Laboratories, was identical to that used by EPA's Health Effects Research Laboratory in carpet bioresponse testing. uplicate tests were conducted for each of three samples received from the Consumer Product Safety Commission: two previously used carpet samples plus mock (empty bags) samples. n emissions characterization team from the Contractor evaluated the experimental system and concluded that the test system developed by Anderson Laboratories was not suitable for carpet chemical emissions characterization because of poor reproducibility, non-uniform thermal conditions, and emissions from the source chamber itself. -hour bake cycle prior to the dynamic mode is ot typical of indoor air characterization methods.
