Health Hazard Evaluation Report No. HETA 82-089-1213, Immunology Branch Laboratory, Centers for Disease Control Atlanta, Georgia

摘要

Five of seven pregnancies of Immunology Branch (IB) employees or of their spouses had ended in spontaneous first-trimester abortions within an 8-month period from May to December 1981. In December 1981, all 7 women concerned were interviewed. On January 5, 1982, a NIOSH industrial hygienist conducted a walk-through survey of the laboratory; reviewed potential mutagenic, teratogenic, and embryotoxic effects of 83 chemicals found in the lab; and measured face velocities of laboratory hoods. Although many substances used in the laboratory were potentially mutagenic, teratogenic, or embryotoxic, no definite causal agent was identified. General laboratory ventilation was excellent.
