Survey for N-Nitroso Compounds at Mohawk Tannery, Nashua, New Hampshire, Report No. IWS-72-29.
NIOSH 1979 Jan:12 pages
Environmental samples were collected on October 12, 1978, to determine whether N-nitroso compounds were present or formed in the leather tanning industry where the precursor compound may be used as a part of the tanning process at the Mohawk Tannery (SIC-3111) in Nashua, New Hampshire. N-nitrosodimethylamine (55185) (NDMA) concentrations were discovered in the atmosphere of this facility at all stages of production except the new beam house area. The highest concentration was 8 micrograms per cubic meter, found in the loft above the unhairing process. The highest concentration in the production area was about 3 micrograms per cubic meter, found in the dye room. The remainder of the samples ranged from 0.03 to 1.2 micrograms per cubic meter. The author discusses possible routes of introduction and/or contamination and suggests that retanning, coloring and fat liquoring process area may be the site where NDMA is produced or introduced as a contaminant.
