description The invention discloses an organic combined pollution sediment toxicity discrimination method. The method comprises the following steps: 1) domesticating chironomidae larvae; (2) pretreating the organic composite pollution sediments; (3) extracting a sediment extracting solution; and 4) testing: separating interference components of the sediment extracting solution to obtain components for biotoxicity testing, finding toxic components in combination with chironomidae larva in-vitro toxicity testing, and then carrying out scanning analysis and spectrum library comparison on the toxic components and tracking specific toxic pollutants. According to the organic combined pollution sediment toxicity discrimination method, common biological tests are adopted, the toxicity of the sediments can be reflected economically and visually, the test requirements of most of laboratories are met, the method can be popularized and used, in addition, the detection range can be narrowed, specific toxic organic pollutants can be d
