On transferring to CWS from the Biological Sciences Division of the National Research Council, Norstrom wrote to the regional directors inviting their suggestions as to what issues should get priority treatment by the new lab. Perhaps because toxicolo- gy was still an unfamiliar field to most wildlife biol- ogists, the response was, in Norstrom's words, "a rather resounding ;"^^ He then set about trying to define his role within his own perception of how CWS could contribute to toxic chemicals and wildlife issues within the agency. Norstrom took action to build up the capability of the unit by recruiting a chemist, Henry Won. Over the next 25 years, the Chemistry Section played a key role in hundreds of investigations into the presence of toxic contaminants in wildlife. As the scope and complexity of the challenge became more evident, Tony Keith was able to secure additional resources to expand the Toxic Chemicals team. A critically important relationship began in 1972, when David Peakall applied to CWS for a research scientist's position in toxicology. Peakall had been working at Cornell University for several years, exploring the physiological action of persis- tent environmental chemicals — organochlorine pes- ticides, PCBs, and heavy metals in particular — on birds. His testimony before hearings into the effects of DDT contributed to getting that pesticide banned in the United States, and his extensive work on pesti- cide-related eggshell thinning in doves, ducks, and raptors was complementary to Richard Fyfe's f
