Older chemists remember the first electron capture chromatograms in the 1960s with the unidentified peaks that turned out to be the PCBs. Vigilance to protect both wildlife and human health from any unanticipated effect of chemical technologies is required now more than ever. Serious and important issues therefore remain. The argument, for example, that genetic defects alone can not account for the abnormalities in the Florida panther population, and that one or more contaminants might be involved, deserves to be expanded.
