对江南某市饮用水中微囊藻毒素(MC-LR、MC-RR、MC-YR)含量进行调查,并进行初步的健康风险评估。2010年6月—2011年5月,按月采集该市各城区饮用水,样品经C18固相萃取柱净化富集后,采用超高效液相色谱-电喷雾三重四级杆串联质谱对3种典型的微囊藻毒素进行定量分析,并应用水环境健康风险评价模型对监测结果进
The contents of microcystins (MC-LR, MC-RR, MC-YR) in drinking water in a certain city of Jiangnan were investigated, and preliminary health risk assessment was conducted. From June 2010 to May 2011, drinking water of each city in the city was collected on a monthly basis. The samples were purified by C18 solid phase extraction column and purified by ultra performance liquid chromatography-electrospray triple quadrupole mass spectrometry A typical microcystin quantitative analysis, and application of water environment health risk assessment model of the monitoring results into
