Adverse effects of 15 ppm of p,p'-DDT on three generation of Japanese quail.

Abstract

This study deals with the effects of administering 15 ppm of p,p′-DDT in the diet of Japanese quail (Coturnix coturnix) over three generations. Four parameters were measured: (1) egg production, (2) egg fertility, (3) number of abnormal eggs produced, and (4) egg residue concentrations. A comparison of first- and third-generation data shows that egg production decreased slightly, fertility and percentage fertility decreased substantially, the production of abnormal eggs increased, and residue concentrations in the eggs increased. The study suggests that the duration of exposure may be as important as the concentration of DDT administered.
