Abstract:

In recent years, red tide pollution in China has become increasingly serious, leading to a number of shellfish poisoning cases, thereby posing a threat to human health and safety. Okadaic acid (OA) and its analogs (dinophysistoxins, DTXs) are the most widely distributed diarrhetic shellfish poisons, which result in acute diarrheal toxicity and various types of chronic toxicity. It is imperative to establish a method for determination of OA related toxin residues in biological fluid samples, so that accurate diagnosis of poisoning in patients is possible. The present paper briefly introduced the main physicochemical properties, poisoning incidents, toxicological effects for the toxins, also summarized recent progress on the metabolic rules and detection methods for OA related toxins in biological samples.
