摘要：The ecotoxicological effects of aniline on Lemna minor have been evaluated based on both morphologicaland physiological responses in this paper. The results showed a significant inhibition to frond number andarea, growth index, and biomass of L. minor. The contents of both chlorophyll a and b went down significantlyafter exposure to aniline. Aniline shows an acute toxic effect on the vegetative growth of L. minor and theeffect is correlated with its concentration. Aniline might impact the growth of L. minor through destroying itsphotosynthesis. The activities of CAT, POD and SOD shown different responses to aniline at different times,but higher concentration of aniline and persistence would be more harmful to L. minor according to thechanges of the activities of antioxidant enzymes. L. minor could be used as an indicator to monitor theexistence of aniline in water bodies.
