Perchloroethylene, the solvent used by 90% of U.S. dry cleaners, is rated a possible carcinogen (Group 2A) by the International Agency for Research on Cancer. The dry cleaning industry has begun to utilize passive badges to document perchloroethylene exposures. Although available in the commercial market, the passive badges had never been evaluated in dry cleaning operations. The objective of this study was to compare passive badge samplers to charcoal tubes for perchloroethylene monitoring in dry cleaning facilities. Researchers collected 240 paired, side-by-side personal and area samples throughout twelve dry cleaning facilities in the United States. Exposure samples were collected from operators, pressers and in selected areas of the dry cleaning facilities. Both a passive badge sample and 100 mg/50 mg coconut shell charcoal tube sample was collected, side-by-side, on an individual's lapel during an eight-hour work shift. All samples were analyzed for perchloroethylene according to NIOSH method #1003 for halogenated hydrocarbons. Quality control samples were prepared by spiking high purity (99+%) perchloroethylene onto both sampling media. Perchloroethylene exposures ranged from 0.5 parts per million to 23 parts per million, with a mean exposure of 5 parts per million. Results indicate the passive badges slightly overestimated the exposure with a mean difference of 0.1 parts per million. The difference between the passive badges and the charcoal tubes was not statistically different among the area and personal samples. A regression analysis yielded a statistically significant relationship between the methods and an R2 = 0.98 (p-value< 0.0001). These results indicate that passive badges are an effective alternative to charcoal tubes to monitor perchloroethylene exposure in dry cleaning operations.
