Method for determination of whole wastewate toxicity

Abstract

A method for determination of whole wastewater toxicity including: measuring the zebrafish embryo toxicity indexes of wastewater samples full-scale of a plurality of wastewater treatment plants and preprocessing obtained data, the zebrafish embryo toxicity indexes including traditional toxicity indexes and behavioral toxicity indexes; establishing whole wastewater toxicity prediction models for wastewater based on different target variables, with the traditional toxicity indexes as target variables and the behavioral toxicity indexes as features; and inputting behavioral toxicity index data of zebrafish embryos of a to-be-tested wastewater sample into the whole wastewater toxicity prediction models; selecting a corresponding prediction model based on a prediction result of the target variables, to obtain a whole wastewater toxicity of the to-be-tested wastewater sample.
