Although many studies have been conducted to minimize the effects of microalgae reproduction today, these studies are limited and not sufficient. Studies are predominantly prediction of toxic or harmful microalgae growth, but this is not possible because the environment is very diverse. However, the place, time and effects of potentially toxic microalgae should be known to the local people. The studies on the spreading areas, living strategies and the factors affecting the harmful and toxic phytoplankton species observed in our country and in the world seas are important for the protection of both ecosystem and human health.

Poisons from the Diarrhetic Shellfish Poison (DSP) species have attracted attention in recent years with the multiplication of dinophysis algae. Methyl ocadaic acid, a species of these poisons, is found during the reproduction of dinophysis species. Diarrhetic Shellfish Poison Group (DSP) toxins found in shellfish include ocaic acid group toxins, pektenotoxin produced by dinophysis species and yessotoxin produced by prorocentrum species. The toxins of the ocadaic acid group are the dinophysis toxins DTX1, DTX2, DTX4 and the acyl derivatives DTX3.

Toxicin1 (DTX-1) analyzes which are among the LC-MS / MS method (liquid chromatography - mass - mass spectrometry method) and Diarrhetic Shellfish Poison Group (DSP) intoxication analyzes are also performed within the scope of biotoxin analyzes in authorized laboratories. These analyzes are based on standards and test methods published by domestic and foreign organizations. The standard considered in this respect is:

  • TS EN 16204 Foodstuffs - Determination of lipophilic algae toxins in shellfish and shellfish by LC-MS / MS (octadaic acid toxins, yessotoxins, azaspiracids, pectonotoxins)
