Dose-response relationships can be affected significantly by time. For example, the time to response when examining the relationship of the exposure to the outcome can be influenced by a latent period between exposure and the outcome. If the effects are measured too soon after the exposure, no ...

Dose-response relationships have received a generic treatment in all general textbooks of toxicology, such as those by Loomis (1974), Doull et al. (1980), and Hapke (1975). The statistical risk of experiencing an effect from an exposure to a chemical can be attributed to the interaction of...

Theoretical H2 concentration profiles and dose-response relationships between H2 concentration and trace gases oxidation rates were integrated to predict the impact of H2 on microbial community functioning. While most H2 is oxidized within 1 cm of H2 point sources, trace gases oxidation is predicted ...
Dose-response relationships for resetting of human circadian lock by light.Presents evidence that humans are much more sensitive to light than initially suspected and supports the conclusion that they do not differ qualitatively from other mammals in their mechanism of circadian entrainment.Boivin...
Exposure in investigations of dose-response relationships can be characterized in different ways, including peak exposure; duration of exposure at or above a set level; average exposure, which is a time-weighted average of exposure; orcumulativeexposure, which is the sum of time-weighted exposures....
