    Comment "A major advantage of bioanalytical tools is their capability of detecting the combined toxicity of mixtures of known and unknown compounds with the same toxic mode of action, whereas chemical analysis can only quantify known, targeted chemicals. By measuring the sum toxicity of a sample, the bioassay approach is also more risk-oriented as it explicitly accounts for the differential in toxicity across different chemicals. A suite of bioassays further enables toxicity assessment across multiple compound groups of varying toxic modes of action. In this way, a comprehensive bioanalytical test battery provides an integrated measure of the toxicity of all or many of the biologically active substances in a sample.Reference: Anita Poulsen, Heather Chapman, Frederic Leusch and Beate Escher.

    Definition "in bioanalytical assessment (in vitro bioassays), measure of the toxic potency directly without having to determine the concentration of the individual congeners11 congener [ IATE:3509884 ]" Reference "COM-Terminology Coordination, based on:Ingrid Keupers. Water Quality Assessment: Determining Dioxin Potency by Means of the CALUX Bioassay. June 2010, http://www.scriptiebank.be/sites/default/files/92230f37ecc3b5e873d67cf0d3441cb8.pdf [12.3.2014]"
    Comment "BEQs are directly related to the overall toxic equivalents (TEQs) determined in in vivo toxicity studies.The most commonly used method is to calculate the BEQ as the ratio between the concentration of the reference compound TCDD and the concentration of the sample both at the same percentage of the maximum response.Another method is to calculate the BEQ as the ratio between the slope of the sample dose response curve and the slope of the TCDD dose response curve.See also TEQ [ IATE:1055272 ]"
