|
This study was attempted to carry out the effects of heavy metals when sea urchins (Hemicentrotus pulcherrimus, Anthocidaris crassispina, Scahhechinus brevis) formed early embryos. Results of the experiment for the effects of heavy metals on the development of sea urchins, in most sea urchins, the ranking of heavy metals according to decreasing effects upon fertilization and development of urchin eggs was follows: Hg, Cu, Zn, Cd, Ni, Cr, Pb, As,and Fe. In addition, in most heavy metals, the ranking of experimental animals according to decreasing effects upon fertilization and development of urchin eggs in the same concentration of heavy metals was follows: H. pulcherrimus, A. crassispina, and S. brevis.
