The ETEAM study was an evaluation of several low-tier models commonly used in the estimation of exposure to chemical agents at the workplace. The aim of these low-tier models is to offer simple, but conservative estimates. Amongst others, the study included a validation of the models against measurement data in order to estimate the level of conservatism. The results were that the level of conservatism of the models is variable. The study also included a simple stratification by model parameters to gain a better understanding of non-conservative estimates.
This analysis extends this stratification into more combination of parameters and finer partitions. The main results are that the ECETOC TRAv3 model tends to underestimate exposure when local exhaust ventilation is present and that the Stoffenmanager includes a specific set of parameters responsible for most of the non-conservative estimates of that model. This analysis also provides information about the size of the underestimation of some models.
