<abstract displayLabel="Summary">Based on the assumption of lognormality, several methods have been proposed for evaluating occupational exposure lognormality of the distribution of TWA values needs to be confirmed for various averaging times. In the present article, these data will be used to examine the distributions of TWAs for 7.5, 15., 30, and 60 min</abstract>
