Abstract
Area and personal breathing zone samples for nitrous oxide (10024972) were taken at a dental office (SIC-8021) in Fort Lee, New Jersey on October 5, 1978. The evaluation was requested by the dentist on behalf of 3 affected employees. Breathing zone concentrations of nitrous-oxide ranging up to 430 parts per million (ppm) were measured during dental work. Mercury (7439976) concentrations up to 0.02 milligrams per cubic meter (mg/m3) also were detected. The recommended exposure concentrations for nitrous oxide and mercury are 50ppm and 0.1mg/m3, respectively. The author concludes that a health hazard exists due to nitrous-oxide exposure. Recommendations include elimination of nitrous-oxide leaks, modifications to the exhaust system, periodic urinalysis for all employees, and prompt and proper cleaning of mercury spills.
