APPLICABILITY: This method has not been used to evaluate field air samples. The method is based on a preliminary investigation analyzing field wipe samples collected during a health hazard evaluation at a facility producing birth control pills [1]. Appendix 1 contains information on recovery of analytes from wipe samples. INTERFERENCES: Any compound that elutes at the same HPLC retention times may interfere. OTHER METHODS: No validated methods were found.
