Evaluation of mysids and sea urchins exposed to saxitoxins

Highlights • A specie of mysid and two of sea urchins were exposed to saxitoxins in different toxicological tests. • The acute test with Mysidopsis juniae showed mortality at a LC50 = 2.34 μg/L STX eq. • The values of EC50 found to sea urchins showed effects of abnormality to both larvae. • Differen...

Zusammenfassung:	Highlights • A specie of mysid and two of sea urchins were exposed to saxitoxins in different toxicological tests. • The acute test with Mysidopsis juniae showed mortality at a LC50 = 2.34 μg/L STX eq. • The values of EC50 found to sea urchins showed effects of abnormality to both larvae. • Different sensibilities could be compared (EC50 = 2.96 μg/L for L. variegatus and 2.06 μg/L for A. lixula ). • A. lixula is another option available to ecotoxicological biomonitoration.
