| Abstract |
A time-integrated sampling system interfaced with a toxicity-based assay is reported for monitoring volatile toxic industrial chemicals (TICs). Semipermeable membrane devices (SPMDs) using dimethyl sulfoxide (DMSO) as the fill solvent accumulated each of 17 TICs from the vapor phase. Uptake kinetics experiments for one of these compounds (acrolein) indicated that it was significantly sequestered (i.e., 10 percent of the 24 hr maximum) in as little as 10 min and was concentrated by a facto fo over 200 in 24 hr as measured using both mass aod toxicity assays. The effect of each of the TICs on the Microtox bacterial luminescence assay was determined both from a direct assay and a vapor accumulation assay using SPMDs. Microtox EC(sub 50) values (concetrating yielding 50 percent inhibition) were determined for each of the TICs analyzed and ranged from 0.070 parts per million volume (ppmv) for diketene to 322 ppmv for 1,2-dibromoethane. The rank order of the Microtox EC(sub 50) values for each compound measured directly from liquid was simular but not identical to the Apparent (APP) EC (sub 50) values determined frm the vapor accumulation assay. |
