Ecotoxicity Testing
- Acute and chronic toxicity tests are performed for terrestrial organisms including avian, mammalian, nontarget arthoprods, and earthworms.
- The Organization for Economic Cooperation and Development (OECD) test guideline has developed specific tests to test toxicity level in organisms.
- LC50 is the acute toxicity test which tests for the concentrate of tissue at which it is lethal to 50% within 96 hours. The test may start with eggs, embryos, or juveniles and last from 7 to 200 days.
- EC50 is the effective concentration at 50% which is the concentration which causes adverse effects in 50% of the test organisms.
- Endocrine Disruptor Screening Program (EDSP0
Tier 1 screening battery
- Endangered species assessments.
- Persistent, Bioaccumulative, and Inherently Toxic (PBiT) assessments using the Quantitative Structure-Activity Relationships (QSARs) to categorize regulated substances. - Bioaccumulation in fish using the Bioconcentration Factor (BCF) methods.

Famous quotes containing the word testing:
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
