چکیده
Spermiotoxic, embryotoxic and cytotoxic effects of the widely used biofouling biocide copper pyrithione (CuPt) were evaluated in bioassays to examine inhibition fertilization rate, offspring quality on early development sea urchin Paracentrotus lividus. CuPt was non-spermiotoxic for rates but frequency embryonic malformations increased a concentration-dependent manner when eggs fertilized with CuPt-exposed sperm. EC50 calculated be 13.58 ?g/l embryotoxicity. While normally developed plutei decreased, number larvae skeletal deformations increased. The IC25 IC50 values cytotoxicity assays 12.79 47.85 ?g/l, respectively. study revealed statistically significant decrease mitotically dividing cells, increase percentage interphase cells chromosomal abnormalities exposed cells. According these results, can said have highly toxic effect embryos at applied concentrations. This situation suggests that there may potential risk marine contamination this species.
