Abstract
The International Chemical Workers Union requested an evaluation of dermatitis and reproductive system disorders among workers exposed to oryzalin (19044883), dichlorobenzidine (91941) (DCB), and benzidine (92875) at the Bofors-Nobel/Lakeway facility (SIC-2865, SIC-2879), Muskegon, Michigan. Exposure to DCB was measured from two personal breathing samples and the results ranged from not detectable to 6.5 micrograms/cubic meter (microg/m3). Area samples for DCB were also taken. Surface contamination samples revealed DCB on the packout locker room surfaces and inside the operator's personal protective equipment. Exposure to airborne oryzalin for six full shift workers ranged from not detectable to 130microg/m3, with a mean of 28microg/m3. Dinitrochlorobenzene (25567673) (DNCB) was detected in air at 70microg/m3 and on surfaces at 6microg/100 square centimeters. Workers exposed to oryzalin reported no adverse reproductive effects. Of 36 workers exposed to DNCB, 19 had skin problems. Bladder cancer was documented in 10 workers with a mean time from first exposure to benzidine to diagnosis of 13.3 years. The authors conclude that a potential hazard existed from dichlorobenzidine exposure. The authors recommend improved housekeeping, explanation of the medical surveillance program to all workers, and continuation of the bladder cancer screening program.
