Vertebral Abnormalities in Juvenile Inland Silversides 'Menidia beryllina'Exposed to Terbufos during Embryogenesis

摘要

Embryos of the inland silverside, Menidia beryllina, were exposed to a nominalconcentration of 50 micrograms terbufos/1 during the first five days of embryogenesis. Silversides were maintained in clean dilute seawater until 37 days after hatching. Radiographs revealed compressed and fused vertebrae and dorsal-
