• Description:
  Within the framework of Registration, Evaluation, Authorization, and restriction of CHemicals (REACH), occupational exposure models are often used to predict the levels of exposure at a workplace. Poor inter-assessor agreement with their use poses a concern that may lead to different and dangerous risk conclusions. TREXMO (v1, 2016), a web tool providing parameter translations between six exposure models under REACH, is expected to improve the inter-assessor agreement. In this study, 18 assessors performed exposure assessment for six exposure situations within and outside the framework of this translation tool. In more than half of the evaluated cases, the results showed better agreement between assessors selecting the exposure parameters within the framework of TREXMO than when manually coding. The most affected were the parameters related to activity (such as "handling types" of Stoffenmanager) and exposure control (such as local controls). Furthermore, the agreement between the estimates calculated by different assessors was also improved when performing the translations between the models. For Stoffenmanager, for example, the relative standard deviation of 70-121%, obtained for vapors without applying the translation system, was 29-94% with the translations from ART. These findings showed a potential of TREXMO to impact the inter-assessor agreement. Because the study was limited to 18 assessors and only six exposure situations were assessed, further investigations are suggested. [Description provided by NIOSH]
