WebAug 13, 2024 · A bioassay compares a test sample with an internationally applicable standard substance. It determines the quantity of test sample required to produce an equivalent biological response to that of standard substance. Environmental bioassays are generally a broad-range survey of toxicity. WebIn the third approach, toxicity profiles and their derived hazard profiles are used to select samples with unusually or unexpectedly high bioassay responses for further in-depth effect-directed analysis (EDA). EDA is a powerful strategy to identify emerging compounds that contribute significantly to the toxic load on the environment.
