Accumulation and detoxification dynamic of cyanotoxins in the freshwater shrimp Palaemonetes argentinus

- MCLR and Nod accumulated in the shrimp P. argentinus.
- MCLR accumulated is removed after exposure ends (74% after 3 days).
- GST and GR seems to be involved in MCLR removal after exposure ends.
- First report of Nod in natural fresh water in South America.
- Low levels of Nod caused biochemical disturbances in P. argentinus.
