To sum up, we know that DDT in sufficient quantity will kill eagles. We know that wild eagles carry body burdens of DDT, and that some of this is transferred to the egg by the females. We do not know that the levels in the egg are sufficient to affect hatching; nor do we know that body burdens in wild eagles are sufficiently high to be detrimental. Certainly, however, we have no evidence that the levels we find in eggs and birds are innocuous.
