Abstract
Adult sea urchins, Anthocidaris crassispina, were exposed to 0.1 and 10mgL-1 phenol for 4 weeks. Abnormal sperm development was clearly evident in phenol-treated sea urchins, although no mortality was found throughout the exposure period. Occurrences of multinucleate sperm cells (including spermatocytes to spermatozoa) showed a significant increase from 0.07% in the control to 10.7% and 43.3% in the 0.1- and 10-mgL-1 treatments, respectively (P-1 phenol-treated sea urchins, respectively (P-1 could lower the quality of sperm and reproductive success in sea urchins, which may threaten the survival of these ecologically important species. The observed impairment of spermatogenesis by phenol might also occur in other invertebrate species. © 2003 Elsevier Science (USA). All rights reserved.
