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:
“Traditional scientific method has always been at the very best 20-20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go.”
—Robert M. Pirsig (b. 1928)
