Photographers are experimenting with time-lapse and multiple exposures, which create amazing, impressionistic effects.
Second, we analyzed multiple exposures, which can lead to finding associations by chance alone.
This will lead to competing interests from multiple exposures, which will later act as a confounding factor for the outcome.
Workers often have multiple exposures, however, which may interact to cause the effect.
In most studies, occupational exposures were assessed using questionnaires with broad terms encompassing multiple exposures (VDGF), which appear reasonably effective in identifying subjects significantly exposed to occupational air pollutants [ 10].
In the study of chemicals with multiple routes and chronic exposures, which method of administration appropriately mimics this situation?
Several centers opted to visit homes multiple times to reassess household exposures, which may vary by season (Yiin et al. 2000) or change when families relocate.
It is possible that there are multiple windows of exposure, which may necessitate collection of multiple samples over the course of development.
Our results show that exposure to the same pesticide via multiple exposure routes may increase the magnitude of effects beyond the level predicted from single phase exposures which has clear implications for the aquatic risk assessment of hydrophobic pesticides.
The research supports the proposition that local knowledge adds contextual meaning that complements the physical measurement of environmental contaminants, in order to understand the complex environment in which people live, and the multiple exposure pathways through which they can be affected.
The activities at additional ion channels are often cited as a means of improving specificity; it may, however, be more important to consider the multiple influences on exposure, which could now feasibly be addressed with a PBPK modeling technique.
