Cyanopeptide degradation during exposure to simulated sunlight at pH 9 in lake Greifensee water as the natural log-transformed peak area versus irradiation time (min) a for microcystins: MC-LA (gray), MC-LR (black), MC-RR-group-1024 (blue), MC-LM (green), MC-YR (pink) and MC-MR-group-1013.51 (orange); and b for aeruginosin 298A (green), aerucyclamide A (black), aerucyclamide D (pink), and the cyanopeptolin oscillapeptin J (blue). The filled symbols represent dark controls and the error bars represent one standard deviation
