Abstract

The Thamnotoxkit F™ was evaluated for detecting cyanobacterial toxins as they may be hazardous to human health if they reach drinking water networks or if people are exposed through recreational activity. This test kit is a 24-hour bioassay using larvae of the freshwater anostracan crusacean Thamnocephalus platyurus hatched from cysts. Nine freeze-dried Microcystis aeruginosa samples from freshwaters of Hungary, Germany and Brazil were tested with the Thamnotox test, rat hepatocyte test, mouse test and analysed for microcystins by high performance liquid chromatography (HPLC). It can be concluded that the Thamnotox test is an alternative simple, cost-effective method that may replace the mouse bioassay used previously for determination of cyanobacterial toxicity.
