Landmark epidemiologic study of chromate production workers. The study took advantage of an extensive exposure data base that was concurrent with employment history at the facility. Smoking information was available for over 90% of the cohort, which is rare for historical cohorts. The study is considered one of the most detailed occupational studies ever conducted and is one of the critical studies used by the Occupational Safety and Health Administration for its proposed Permissible Exposure Limit for chromium. At the invitation of OSHA, a Sciences' expert testified at the public hearings on the proposed PEL. The study resulted in two publications in the American Journal of Industrial Medicine (abstracts) and one in Risk Analysis ( abstract) as well as numerous presentations in scientific fora.

Evaluation of epidemiologic studies of asbestos exposure. Sciences has evaluated the vast epidemiologic literature on asbestos, examining risks of mesothelioma, lung cancer, and asbestosis by occupational and residential exposure, and the company maintains a large repository of articles on the subject. The relationship of occupation to risk has been further examined by the relative carcinogenic potency of fiber types, dimension and quantity of exposure.

Analysis of birth defects data on pharmaceutical. Sciences analyzed the data regarding claims of a birth defect resulting from use of a pharmaceutical. The analysis was prepared for presentation at an FDA panel hearing. The analyses were subsequently described in a letter to the journal where the issues were first raised. In the published letter, the epidemiologic limitations of the original paper were described, and proper epidemiologic approaches were recommended.
