Toxicity of the samples was determined with mouse. Bioassay method Intra-peritoneal injection was done toddy strain ♂19-21 grams male mouse, and death time was listed. In conclusion, 33.80, 38.40, 31.20 MU/g (or 777, 883, 718 STX/100gr) were obtained respectively as the toxicity of the samples of three different sampling areas. The toxicity for the areas was 9.7, 11 and 9 times more than standard level (80STX/100 g) and very dangerous for human consumption. The kind of toxin was determined by comparing HPLC graph of sample with standard saxitoxin HPLC graph.
