Results and discussion
Applicant's summary and conclusion
- Executive summary:
Two cases of lung cancer were reported among workers in a small chemical plant producing benzoyl peroxide, benzoyl chloride, and related com pounds. Both workers were exposed to benzoyl peroxyde during its manufacture, and one of them was a smoker. Other compounds to which these workers were exposed included benzoyl chloride and benzotrichloride. Based on the development of lung cancer in others occupationally exposed to these latter two compounds, the au thors suggested that there is causal association between exposure to benzoyl chloride and benzotrichloride and lung cancer. However, the study did not indicate measurement of exposure levels to these or other compounds, nor did it control for the potential influence of smoking habits or exposure to other agents. The authors draw no specific conclusions regarding the risk of benzoyl peroxide exposure, and a review of these data provides no basis for a causal link between benzoyl peroxide exposure and cancer development in the two workers discussed by Sakabe and Fukuda (1977). Rather, as indicated above, the authors attributed the cancer cases to benzoyl chloride and/ or benzoyl trichloride exposure.
