• Description:
  Area and personal air samples were taken on November 14 and 15, 1979 at the offices (SIC-8021) of a dentist in Hillsboro, Ohio to determine possible adverse health effects from exposure to nitrous- oxide (10024972) and mercury (7439976). Personal breathing zone samples were taken on two dentists and two dental assistants. Operating room personnel were exposed to nitrous-oxide concentrations that ranged from 115 to approximately 2,600 parts per million (ppm) per administration, with 75 percent of the samples falling within the 100 to 500ppm range. Area nitrous-oxide samples for the receptionist ranged from 54 to 198ppm. Personnel were exposed to a maximum of 0.036 milligrams per cubic meter (mg/m3) mercury vapor. The authors conclude that personnel are over exposed to nitrous-oxide based on the current NIOSH recommended standard of 50ppm per administration and that exposure to mercury vapor is below the NIOSH recommended standard of 0.05mg/m3. They recommend that a scavenging system be installed to exhaust the nitrous-oxide gas and reduce personnel exposure. [Description provided by NIOSH]
