摘要：In this paper, we studied the toxicity of different concentrations of 2, 2', 4, 4'- tetrabromodiphenyl ether (BDE-47) on Dicrateria inornata. The results showed that the 96 h EC₅₀ value of BDE-47 compound was 165 μg L^-1. By studying the changes of photosynthetic pigments and chlorophyll fluorescence characteristics, the toxicity mechanism of BDE-47 was studied. The results showed that BDE-47 with low concentration (25 ~ 50 μg L^-1) had an induced effect on photosynthetic pigment content, and the BDE-47 with high concentration (100 ~ 200 μg L^-1) had a significant inhibitory effect on photosynthetic pigment content. BDE-47 has inhibitory effect on the fluorescence characteristics of the flagellates, and the inhibitory effect increases with the increase of concentration.
