标准摘要
[中文适用范围]： 本国际标准规定了原水（含有生物质）和处理水（例如自来水）中微囊藻毒素的测定和定量方法。 所描述的方法针对 MCYST-RR、MCYST-YR 和 MCYST-LR 进行了验证。 它也适用于测定这些微囊藻毒素的几种结构变体[1]，但由于缺乏商业可用的标准品和共洗脱，无法做出明确的鉴定。 使用固相萃取 (SPE) 富集微囊藻毒素后，可以遵循世界卫生组织提出的水中 MCYST-LR 1 μg/l 的阈值。 [外文原描述]： ISO 20179:2005 specifies a method for the determination and quantification of microcystins in raw water (containing biomass) and treated water, such as tap water. The method described is validated for MCYST-RR, MCYST-YR, and MCYST-LR. It is also applicable for the determination of several structure variants of these microcystins, but an unambiguous identification cannot be made due to the lack of commercially available standards and due to co-elution.
