Health Hazard Evaluation Report No. HETA-81-189-929, School of Dental Medicine, University of Pennsylvania, Philadelphia, Pennsylvania

摘要

In February 1981, the National Institute for Occupational Safety and Health (NIOSH) received a request from dental students at the School of Dental Medicine, University of Pennsylvania, to evaluate possible health hazards from student exposures to methyl methacrylate vapor (during bridge work) and mercury vapor (during filling work). The students (160 potentially exposed) believed that the present ventilation system in preclinical laboratories B-1 and B-2 may not be effective in removing air contaminants. Personal air samples for methyl methacrylate (4 samples) and mercury (6 samples) were collected on March 26, and May 4, 1981, respectively.
