Toxicologic pathology, 36(3), 449-458 (2008-04-29)
Microcystins (MC) are frequently present in cyanobacterial blooms in rivers and lakes, increasing the risk of toxicity to both animals and humans. There more than eighty reported microcystins, and the present study was undertaken to determine whether MC-LR and MC-RR
Perrine Zeller et al.
Ecotoxicology and environmental safety, 82, 13-21 (2012-06-23)
Microcystins (MCs) are cyclic hepatotoxins produced by various species of cyanobacteria. Their structure includes two variable amino acids (AA) giving rise to more than 90 MC variants, however most of the studies to date have focused on the most toxic

Degradation of algal toxin Microcystin-RR (MC-RR) by ozonation processes was investigated. The degradation rate of MC-RR reached 83.0% at ozone/MC-RR dosage of 6, and the degradation efficiency was decreased with increase of pH or NOM contents. Ozonation byproducts of MC-RR
Gaodao Liang et al.
TheScientificWorldJournal, 11, 20-26 (2011-01-11)
Microcystins (MCs) are well known worldwide as hepatotoxins produced by cyanobacteria, but little is known about the physicochemical properties of these compounds. The dependence of the n-octanol/water distribution ratio (DOW) of MC-RR and -LR to pH was measured by high-performance
Peng Chen et al.
Environmental science & technology, 46(4), 2345-2351 (2012-01-19)
Microcystin-RR (MC-RR) is one of the most common cyanotoxin microcystins in fresh water and is of great concern due to its potential hepatotoxicity. In the present study, Bi(2)WO(6) was synthesized with a hydrothermal method by varying the pH of the
