• Description:
  Volatile N-nitrosomorpholine (NMOR), N-nitrosodimethylamine (NDMA), and N-nitrosopyrrolidine (NPYR) - 3 powerful carcinogens for animals whose effects on humans are unknown - were found last year in air samples in a tire manufacturing plant in Cumberland, Maryland. Airborne NMOR was present at a maximum concentration of 250 micrograms per cubic meter (microg/m3), a level 10 times higher than any nitrosamine concentration previously reported in the rubber industry. Over the following 8 months, ventilation improvements and changes in chemical formulation resulted in a 100-fold reduction in NMOR levels and in elimination from air of other nitrosamines.
