Abstract
Embryos of the inland silverside Menidia beryllina were exposed to a nominal concentration of 50 .mu.g terbufos l-1 during the first 5 d of embryogenesis. Silversides were maintained in clean dilute seawater until 37 d after hatching. Radiographs revealed compressed and fused vertebrae and dorsal-ventral misalignment of pre-and post-zygapophyseal processes. Histopathological examination of representative individuals exposed to terbufos during embryogenesis revealed various vertebral lesions ranging from small hyperostoses to almost complete fusion of some vertebrate.This publication has 0 references indexed in Scilit:
