Assessment of sediment contamination by spermiotoxicity and embryotoxicity bioassays with sea urchins ( Paracentrotus lividus) and oysters ( Crassostrea gigas)
Abstract Gametes (sperm) and fertilized eggs (embryos) of the Mediterranean sea urchin, Paracentrotus lividus , and the Japanese oyster, Crassostrea gigas , were used to investigate the toxicity of two marine sediments, one polluted by polycyclic aromatic hydrocarbons (PAH) and the other by heavy me...
