DDT exposures in a natural history museum--Colorado.

In October 1981, the Denver Museum of Natural History, Denver, Colorado, requested assistance from the National Institute for Occupational Safety and Health (NIOSH) in evaluating occupational exposures to dichlorodiphenyl trichloroethane (DDT) because of concern about possible health hazards (1). Workers potentially exposed to DDT included curators, preparators, and museum assistants involved in cleaning, packaging, and storing animal skeletons coated with the pesticide.
