| Abstract: | In order to evaluate objectively the ecological effects of 2,4 DNT mixed with 6 kinds of nitroaromatic compounds in the ecosystem,the study on the mixtoxicity of 2,4 DNT and other 6 kinds of nitroaromatics to the algae( Scenedesmus obliquus )was carried out.48h EC 50 of monotoxicity of 7 kinds of compunds and 48h EC 50 of mixtoxicity of 2,4 DNT+6 kinds of compounds were measured. Results indicated that there are synergisms between,2,4 DNT+4 NAn,2,4 DNT+4 NAnis, and 2,4 DNT+1,4 DNB as well as antagonisms between 2,4 DNT+4 NT,2,4 DNT+4 NPh and 2,4 DNT+4 NCB. Under the microscope(400 times)3 kinds of toxic symptoms,the inhibition to the filial spores forming and releasing, the irregular big cells appearing,nucleus and cell organs as well as the protoplast distegrating were observed. |
