font size="1" face="Times New Roman"> The uptake and accumulation of microcystin-RR (MC-RR) in fishwas investigated under laboratory conditions and in wild fish. Jenynsia multidentata and Corydoras paleatus were exposed for 24 h to 50 g/L MC-RR dissolved in water. After exposure, liver, gill, brain, intestine, gall bladder, blood and muscle were analyzed for MC-RR by HPLC and analysis confirmed by LC-ESI-TOF–MS spectrometry. Furthermore, wild individuals of Odontesthes bonariensis were sampled from the eutrophic,
