Eutrophication, marine biotoxins, human health

摘要: Eutrophication phenomena in marine coastal waters can today be explained on the basis of natural or anthropogenic causes. Undesirable effects and also sanitary problems both types eutrophication are often produced, but they may differ greatly frequency significance. Some algal biotoxins affect animals man, whilst others man alone. From data currently available it appears that state affected through digestive, respiratory cutaneous apparatus. Four main dinoflagellate biointoxications now recognized: paralytic shellfish poisoning (PSP), neurotoxic (NSP), diarrhoetic (DSP), venerupin poisoning. Other due to a diatom bloom responsible for amnesic (ASP) blue algae blooms which have skin tract. All these toxins considered particular attention is paid to: producing organisms, chemistry components, compromised sea foods, methods analysis, occurrence worldwide, human intoxications, toxicology mechanism action molecular level, therapeutical notes, tolerance levels remarks safety. Attention relationship between PSP DSP since most widespread from toxic dinoflagellates world European Economic Community (EEC) proposing health legislation such as limits official analysis. In view harmful potential eutrophication, current committment various countries concerns control. Finally, important develop suitable monitor research system using all specific standards allowed substances, effective antiodotes against biotoxins.
