Bioassay-Directed Chemical Analysis of Organic Extracts of Emissions from aLaboratory-Scale Incinerator: Combustion of Surrogate Compounds

摘要

A prototype/laboratory-scale rotary kiln (73 kW, 250,000 Btu/h) was used toexamine the chemical composition and biological effects of the emissions produced when the kiln was operated under suboptimal conditions resulting from batch charging. The surrogate wastes evaluated were polyethylene (PE), polyvinylchloride (PVC), toluene (TOL), carbon tetrachloride (CC14), PE + PVC and TOL + CC14. The dichloromethane-extractable organics from particles (collected on filters) and semivolatiles (collected on XAD-2 resin) were evaluated for mutagenic activity using the Salmonella (Ames) mutagenicity assay in strain TA98 (+S9). The mutagenic potencies (revertants/microgram of extractable organics) of the emissions ranked as follows: PE > TOL > PE + PVC > TOL + CC14. The organic extracts from the PVC and CC14 emissions were not mutagenic. (Copyright (c) Gordon and Breach Science Publishers S.A., 1992.)
