When mixed exposures of PERC and other spotting chemicals have been involved, the combined publicity (CE) was determined as follows. Information gathered utilizing the MicroTIP® was electronically recorded on a Rustrak® knowledge logger (Rustrak® Ranger, Gulton, Inc., East Greenwich, RI) and https://www.vapezigarette.de/menthol-erdbeere-sc-liquid downloaded to a portable pc, using Pronto® software.
