| Popis: | Histological and skeletal examinations were performed on rainbow trout (Salmo gairdneri Richardson) alevins reared in 0.00, 0.08, 0.21, 0.39, 1.48, 2.40 or 2.99 ng/ml aqueous benzo(a)pyrene (BaP). Nuclear pycnosis and karyorrhexis were most common in neuroectodermal and mesodermal derivatives and in liver of BaP-treated alevins. Microphthalmia was observed in 17% of the test fish and was frequently associated with a patent optic fissure. Depressed mitotic rates in the retina and brain (but not liver) were observed in alevins reared in 0.21 to 1.48 ng/ml aqueous BaP. Test alevins had a significantly higher incidence of skeletal malformations in the skull and vertebral column, and abnormalities of vertebral arcualia often corresponded to areas of kyphoscoliotic flexures. |
