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

- 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.
