摘要 为了解南方某水源水库中藻类和藻毒素污染状况,探讨适用于连续、批量监测水库藻毒素的常规技术方法,对水源水库中藻细胞密度,藻种,微囊藻毒素(MC)-LR、RR、YR含量进行了为期8个月的监测。结果表明,蓝藻在夏秋季比例较高,微囊藻毒素与蓝藻密度呈一定的正相关,但蓝藻密度和藻毒素的分布规律并不完全一致,MC含量的峰值比蓝藻密度峰值滞后。因此,对蓝藻密度进行在线监测是十分必要的,并建议当蓝藻密度接近或超过限值时应进一步用ELISA方法定性和用HPLC方法定量测定微囊藻毒素含量,形成适用于水源水库的藻毒素监测技术。 To study the pollution level of algae and microcystin in a water source reservoir in South China, a conventional continuous and batch monitoring method applied for reservoir microcystin was investigated, and the algal cell density, algal category, microcystin concentration (MC-LR, MC-YR and MC-RR) in the water source reservoir were monitored for eight months. The results show that cyanobacteria reach the peak during summer and autumn. There is a positive correlation between microcystin concentration and cyanobacteria density, but the distribution of microcystin concentration is not fully consistent with that of cyanobacteria density. Microcystin concentration peak value is later than cyanobacteria peak value. So it is necessary to monitor the cyanobacteria density in on-line mode. It is suggested that ELISA and HPLC methods should be used to perform qualitative and quantitative analysis of microcystin concentration respectively if cyanobacteria density value approaches or exceeds the limit value, which forms a microcystin monitoring technology applied in water source reservoirs.
