Study Notes
Toxicity Tests
- LD50 test determines the dose of a substance that can kill 50% of test subjects, used to measure acute toxicity
- LD50 test is NOT used to determine chronic toxicity or long-term effects of a substance
Determining Toxicity Methods
- Methods used to determine toxicity include in vitro tests, in vivo tests, and epidemiological studies
- NOT a method used for determining toxicity: personal opinions or anecdotal evidence
Acute vs Chronic Toxicity
- Acute toxicity tests measure the adverse effects of a substance after a single dose or short-term exposure
- Chronic toxicity tests measure the adverse effects of a substance after long-term or repeated exposure
- Key difference: duration of exposure and potential for cumulative effects
