适用范围：This international Standard 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[1] of these microcystins,but an unambiguous identification cannot be made due to the lack of commercially available standards and due to co-elution.The threshold value of 1μg/l of MCYST-LR in water,proposed by the World Health Organization,can be followed after microcystin enrichment using solid phase extraction(SPE).
