For substances for which the daily exposure estimates did not result in an RCR > 1 this was not necessary, as the daily exposure estimate is more worst case than the year average estimate and the 'lifelong' exposure estimate.
For prioritised substances for which the toxicological reference value is based on a non-threshold effect (such as for the PAHs), the comparison solely concerned the 'lifelong' exposure estimate.
He translated my PBDE levels -- 36 parts per billion -- into an exposure estimate for my breast-feeding daughter and then compared that with the best-known safe level that scientists can more or less agree on.
A clear understanding of microbial sampler's ability to recover culturable bioaerosols is essential for better exposure estimate and design of future advanced samplers.
Habitat quality is often neglected when ecological risk assessments are performed, despite evidence that inclusion of a quantitative habitat measure can have a significant effect on the overall exposure estimate.
The preliminary occupational radiation exposure estimate gives a value of about 250 man mSv/a, which is half the annual target for ITER and comes essentially from maintenance activities.
The input parameters were chosen in such a way that a worst-case exposure estimate is derived, thereby assuming that each and every training session and match will take place on an STP with rubber granulate, from which each time the maximum amount of substances present will be released.
Thus, the Panel introduced a whole set of new uncertainty factors to adjust the exposure estimate to a 'realistic' level.
The 95th percentile dietary exposure estimate ranged from 0.36 to 2.09 μg/kg/day for infants, toddlers, and other children.
Higher dietary exposure estimate for Pb through the consumption of vegetables grown on wastewater-irrigated fields were reported by Singh et al. (2010) and Mahmood and Malik (2014).
If, as was common, a pesticide was detected on more than one TDS food, contributing exposures from each food were combined to yield a daily exposure estimate to the pesticide.
