toxicity test, the measurement endpoint concerns a sublethal effect (e g , reproduction, growth) or both lethality and sub-lethal effect Acute Toxicity Tests A typical acute toxicity test exposes test organisms to a series of dilutions of a site’s medium and records deaths occurring over a specified period of time, usually 24 to 96 hours Results can be analyzed by comparing percent

the sublethal tests identified a smaller total number of stations as toxic than the standard amphipod survival test(s), yet each of the sublethal tests detected toxicity in some samples that were classified as nontoxic by the amphipod survival test This suggests that sublethal tests and acute tests are complementary rather than redundant and can
