Generation of experimental uptake rates (UR) for > 70 VOCs (7d /100 μg m-3)
Application in German Environmental Survey – VOC exposure assessment
Assurance of transparency concerning UR generation and uncertainty creates basis for decision making and comparability of measurement results.
Exemplarily the uncertainty u(UR) of toluene UR was modelled and determined statistically with own laboratory data (relative standard deviation of actively sampled test gas atmosphere – RSDa and n = 5 exposed passive samplers – RSDp) in line with EN 838 as well as from variation of literature UR – RSD UR,lit.
