慎池不同季节微囊藻水华的冻触藻浆注射小白鼠，其LD50分别为432mg／kg，313mg／kg．287mg／kg，样品含肝毒素或微囊藻毒素（Mierocystin-LR）．毒素用HPLC进行分析制备，得到如下结果：A样、B祥和C样均含Microcystin-LR，此外，A样中还含Microcystin－RR，B样含Microcystin-YR，C样含Microcystin-RR和Microcystin-YR，这反映滇池蓝藻水华在不同季节优势种不一样．优势藻的产毒情况有差别，从而引起水质的季节性变化．

Microcystis blooms of t he dominating species microcystis aeruginosa,M. wesenhergii and M. viridis were collected from Dianchi Lake (South-WesternChina ) at different seasons of the year. All samples were tested by mouse bioassaysand the LD_50, of 3 samples were 432 mg/kg, 3l3 mg/kg, and 287 mg/kg respective-ly. The cells of the algae contained hepat0t0xins or microcystins. The HPl,C (highperformance ll(luld chromatography ) analysis showed that all the three micr0cystissamples c0ntained microcystin I,R. ln addition, sample A (dominating M. aerugi-nosa ) contained microcystin RR, sample B (dom...
