• Description:
  A survey was conducted on December 14, 1977 at the Chrysler Forge and Axle Plant (SIC-3312) in Detroit, Michigan to determine the extent of exposure to N-nitroso compounds in the machine shop environment where cutting fluid was used. The facility employed about 3500 workers over three shifts. Air samples were collected near machines using Cimcool-Five-Star-B (CFSB), Chrysler-Cycleweld- NP6058 (CC), and Grotan (56573047) to detect N-nitroso compounds released during machine operation. Stock solutions and diluted fluid samples taken from the machines were also analyzed to measure N-Nitroso compounds, specifically N-nitrosodiethanolamine (1116547) (NDElA). Undiluted stock solutions of CFSB contained about 600 micrograms per milliliter NDElA; CC and Grotan contained less than 1 microgram per milliliter. Diluted (10 to 1) CFSB collected from machines contained 5 micrograms per milliliter or less NDElA, lower than expected. No other N-nitroso compounds were detected. Atmospheric concentrations of 30 to 50 nanograms per cubic meter NDElA were detected near one of three machines using CFSB; none was detected in any other air sample. The authors suggest that the lower concentrations of NDElA in the used fluids are probably due to decomposition of NDElA to non-N-nitroso compounds. They conclude that the general facility atmosphere was not contaminated by NDElA and that daily exposure in the contaminated area was about 120 nanograms over 8 hours.
