The highest attained exposure concentration corresponded to the maximum concentration value assigned to jobs with an individual's employment history.
The effects of occupational exposure to diesel and gasoline emissions were modeled using 5 exposure metrics: ever exposure, highest attained exposure concentration, duration of exposure, frequency of exposure, and cumulative exposure.
There were no significant associations between "ever exposed" to diesel emissions and lung cancer, and trends were "consistent" with an E-R pattern for highest attained exposure and cumulative exposure.
With the use of a suitable cover, we can attain long exposure time, high stability, and decreasing of QDs depositing that are very important in vivo parameters.
The results were consistent with those presented in Hendriksen et al. and suggest that smaller children need higher weight-adjusted doses of i.v. ARS to attain DHA exposures similar to children with higher body weights.
It gave an overall ERR for lung cancer of 0.21 %/WLM, which was modified by time since exposure, attained age, and exposure rate.
When replacing cumulative exposure at the end of follow-up with attained cumulative exposure 1 year prior to the diagnosis of cancer (in order to minimise the chance of reverse causation) the point estimates remained statistically significantly protective.
