AbstractMicrocystin-LR (MCLR) and linear alkylbenzene sulfonate (LAS) are commonly found in eutrophic lakes due to toxic cyanobacterial blooms and exogenous organic compounds pollution. However, the ecotoxicological risk of their combination in the aquatic environment is unknown. This study investigated the effects of MCLR. LAS and their mixture on duckweed (Lemna minor) growth and physiological responses. MCLR accumulation in duckweed, with or without LAS, was also examined. Growth of duckweed and chlorophyll-a contents were significantly reduced after 8d exposure to high concentrations of MCLR (>= 3 mu g/ml), LAS (>= 20 mu g/ml) and their mixture (>= 3 + 10 mu g/ml). After 2 d of exposure, superoxide dismutase activity and glutathione content in duckweed increased with increasing concentrations of MCLR, LAS and their mixture, with a significant difference observable after 8 d of exposure. When MCLR and LAS concentrations were lower (<= 0.1 + 1 mu g/ml), the interaction of them is synergistic, but when the concentrations were higher, the synergy was weak. MC accumulation was much higher at 2 d than at 8 d when duckweed was exposed to lower concentrations of MCLR (<= 3 mu g/ml) or MCLR-LAS (<= 3 + 10 mu g/ml). Furthermore. LAS significantly enhanced the accumulation of MCLR in duckweed, even with LAS concentrations as low as 0.3 mu g/ml (environmental concentration), indicating that greater negative ecological risks and higher MCLR phytoremediation potentials of duckweed might occur in MCLR-LAS-concomitant water.
