8.13 Dose Response Curve
Notes
A dose-response curve plots dose against the percent of the population affected.
- Threshold: the dose where effects begin.
- $\mathrm{ED_{50}}$: effective dose for 50% (non-lethal effects).
Practice
The threshold dose is:
Below it, no effect.
Dose-response curves are usually:
Rise then level off.
Data for human dose-response usually come from:
Ethical limits.
