[目的]在野外自然环境下研究微囊藻毒素3种异构体与环境因子的关系。[方法]应用高效液相色谱,对北方某水库5个采样点水体中微囊藻毒素3种异构体(MC-LR、RR和YR)进行了为期1年的监测,研究3种异构体与环境因子的相互关系。[结果]3种异构体均与叶绿素a呈现正相关关系;LR和YR异构体均与水温呈显著线性正相关,但是RR异构体与水温的相关性不明显;LR和YR异构体与总氮、硝酸盐氮和有机氮的相关性比较显著,而RR异构体只与硝酸盐氮存在显著负相关关系;LR和RR均与总磷和有机磷呈现显著正相关,而磷对YR异构体的影响相对较小,它们之间的相关性不明显。[结论]研究了微囊藻毒素3种异构体与叶绿素a、水温及氮、磷等环境因子的关系,并初步分析了其原因,对控制水体蓝藻的生长和毒素合成有一定的意义。
[目的]在野外自然環境下研究微囊藻毒素3種異構體與環境因子的關繫。[方法]應用高效液相色譜,對北方某水庫5箇採樣點水體中微囊藻毒素3種異構體(MC-LR、RR和YR)進行瞭為期1年的鑑測,研究3種異構體與環境因子的相互關繫。[結果]3種異構體均與葉綠素a呈現正相關關繫;LR和YR異構體均與水溫呈顯著線性正相關,但是RR異構體與水溫的相關性不明顯;LR和YR異構體與總氮、硝痠鹽氮和有機氮的相關性比較顯著,而RR異構體隻與硝痠鹽氮存在顯著負相關關繫;LR和RR均與總燐和有機燐呈現顯著正相關,而燐對YR異構體的影響相對較小,它們之間的相關性不明顯。[結論]研究瞭微囊藻毒素3種異構體與葉綠素a、水溫及氮、燐等環境因子的關繫,併初步分析瞭其原因,對控製水體藍藻的生長和毒素閤成有一定的意義。

[Objective] The relationship between three isomers of microcystins and environmental factors were studied in the fields.[Method] Three isomers of microcystins (MC-LR,RR and YR) from water of five sampling spots in a northern reservoir were observed for one year with High Performance Liquid Chromatography analytical method in order to study the relationship between three isomers and environmental factors.[Result] The three isomers of microcystins showed positive correlation with chlorophyll a;LR and YR isomers all had significant linear positive correlations with the water temperature,but the RR isomer showed no significant correlation with the water temperature;LR and YR isomers had relatively significantly correlativities with the contents of total nitrogen,nitrate nitrogen and organic nitrogen,while the RR isomer only showed a significant negative correlation with the content of nitrate nitrogen;LR and RR isomers both showed significant positive correlations with the contents of total phosphorus and organic phosphorus,while the phosphorus hardly affected the YR isomer and showed no evident correlation.[Conclusion] The relationship between three isomers of microcystins and environmental factors such as chlorophyll a,water temperature,nitrogen,phosphorus were studied and investigated the reasons,which might offered a reference for controlling the growth of blue algae in water and toxin synthesis.
