A walk through survey was conducted at the International Dyestuffs Corporation (SIC-5161), Clifton, New Jersey to investigate worker exposure to o-dianisidine (119904) based dyes as part of the benzidine congener based dye workers exposure study. The company was a dye distribution firm which blended and repackaged imported and domestic dyes for resale. Airborne samples and surface wipe samples were collected for dye analysis. Urine samples were also collected along with personal monitoring samples for the airborne o- dianisidine based dye, Direct-Blue-1 (2610051). Urine samples from five dye exposed workers were analyzed for o-dianisidine and o- tolidine (119937); three of 22 samples contained 1.4 to 5.4 parts per billion (ppb) o-tolidine, and two contained 2.3 to 2.8ppb o- dianisidine. Mutagenic activity in urine specimens was determined using the Ames Assay. Smoking, but not exposure to dyes, strongly contributed to the mutagenic activity in the urine. As respiratory protection was used in all locations in the facility where exposure to dyes could occur, it was difficult to determine whether exposure to dyes caused positive mutagenicity or not. Data suggested that at the exposure levels in this study, there was no association between exposure to dye and mutagenicity in these workers.
