Abstract:

In this study, the toxicity of vanadium to three invertebrate larvae (Artemia salina, Crassostrea gigas, Paracentrotus lividus) was assessed. Two criteria were mainly observed: percentage of normal developed larvae and growth of normal larvae. After short term experiments (2 days), toxic effect of vanadium appears for a concentration of 50 mu g/l (C. gigas larvae), 100 mu g/l (P. lividus pluteus). A. salina are less sensitive, and toxic effects appear only after 8 days of contact with vanadium concentration of 250 mu g/l. For the three species tested, growth of larvae was not affected by the introduction of vanadium up to 750 mu g/l in the rearing medium, but high teratogenic effects occur on the development of sea urchin pluteus. The toxic effect of vanadium appeared at 50-100 mu g/l for marine larvae, this observation was in contrast with results previously obtained with adult marine organisms.
