This book explains the effects of the organochlorine pesticide endosulfan on two embryonic stages (days 6&12) of the chick. It provides experimental methods such as eggs incubation and treatment, histological procedures for skeleton staining and tissue preparations. The book also illustrates the morphological and skeletal descriptions of normal and abnormal chick embryos with emphases on the incidence of external and skeletal malformations following endosulfan treatments. Besides, a complete description of the histological and histopathological characteristics of the developing kidney...

The present study explored the morphological and skeletal impacts of the pyrethroid pesticide cypermethrin on the growing larvae of the guppy fish (from the age of 5-day-old until the age of 45-day-old) as well as the histopathological impacts of this pesticide on the gills and trunk mesonephroi of the 45-day-old guppy juveniles. The results obtained from this study concluded that cypermethrin exhibited teratogenic effects on the developing guppy fish larvae in terms of external malformations, skeletal changes as well as severe histopathological lesions on the gills and kidneys compared to...
