title: Residual DDT in two successive generations of quail and their eggs.
abstract: Gas chromatographic analysis of residual DDT levels following external treatment of parent eggs shows contamination to be present not only in first generation quails but also in second generation eggs laid at the beginning of the laying period and in chicks and adults hatched from them. However, the amount of pesticide detected in second generation eggs laid lately and in all third generation eggs was not significantly higher than that found in control samples.
