| 中文摘要: |
| 应用高效液相色谱，对北方某水库水体中溶解性微囊藻毒素(extracellular microcystin，EMCs)和藻类细胞内微囊藻毒素(intracellular microcystin，IMCs)的3种异构体(LR、YR、RR)进行了为期1年的监测，研究了EMCs和IMCs随时间的变化规律及相互关系。结果表明：EMC-RR和IMC-RR的全年变化规律非常一致，在9月初之前其含量比较低，随后迅速上升并在10—11月份同时出现峰值；EMC-LR、IMC-LR、EMC-YR和IMC-YR全年出现多个起伏，且存在明显的差异，其峰值出现时间也不一样，EMC-LR和EMC-YR峰值出现在8—9月，而IMC LR与IMC-YR的峰值则出现在9月份中下旬。IMC LR和IMC RR是藻类细胞内主要毒素，但是2种异构体所占总的细胞内毒素的比值并不是固定的，5—12月份其比值不断下降。 |
| 英文摘要: |
| The variations of extra cellular microcystin (EMCs) and intra cellular microcystin(IMCs), including their enantiomers (LR, YR, RR), in a reservoir, located in North China, were monitored by high performance liquid chromatography for one year. The variation law and relationship between these two microcystins were analyzed. The result indicates that the EMC-RR and IMC-RR vary synchronously. Their contents are very low before September, and then increase rapidly until the peaks occur in October and November. The annual variations of EMC LR,IMC-LR, EMC-YR, IMC-YR have many obvious differences and fluctuate within one year. Their peak contents appear at different times. The maximum contents of EMC LR and EMC-YR occur in August or September, while the peak contents of IMC-LR and IMC-YR occur in late September.The IMC LR and IMC RR are the main toxins of Microcystics. Their proportions to the total concentration of intra cellular microcystin are not constant, which decrease continuously from May to December. |
