| Overview | microcystins are a class of heptapeptide monocyclic hepatotoxins with biological activity. Polypeptides have multiple isomers due to differences in the composition of the two variable amino acids. Among them, the most common and most abundant are microcystin LR, microcystin RR, microcystin YR (L, R, Y represent leucine, arginine and tyrosine respectively). With water solubility and heat resistance, heating and boiling can not destroy the toxin; Water treatment process of coagulation sedimentation, filtration, chlorination, oxidation, activated carbon adsorption can not be completely removed. Soluble in water, methanol or acetone, non-volatile, resistant to pH changes, the chemical nature is quite stable, the natural degradation process is very slow. The recommended standard of microcystin in drinking water was 1.0 μg/L World Health Organization (WHO), and the content of microcystin in drinking water was limited to 1.0 μg/L in the "drinking water Health Standards" (GB5749-2006). Microcystins in water can be determined by high performance liquid chromatography and indirect competitive enzyme-linked immunosorbent assay. |
