HHE determination report no. HHE-79-113-728, Olin Chemical Company Brandenburg, Kentucky.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 79-113-728, 1980 Aug; :1-12
Environmental and medical surveys were conducted on September 26 and 27, 1979, and January 14 to 18, 1980 to evaluate dinitrotoluene (25321146) (DNT) and toluene-diamine (25376458) (TDA) exposures to workers in the TDA unit of the Olin Chemical Company (SIC-2810) in Brandenburg, Kentucky. The evaluation was requested by an authorized representative on behalf of an unspecified number of employees. DNT concentrations ranged from 0.013 to 0.42 milligrams per cubic meter (mg/m3) during the initial survey and from undetectable to 0.10 mg/m3 during the follow up survey. TDA concentrations ranged from 0.008 to 0.39 mg/m3 during the initial survey and from undetectable to 0.038 mg/m3 during the follow up survey. All DNT values were below the OSHA standard of 1.5 mg/m3. No accepted TDA standard existed. Medical findings included a significant reduction in sperm count among exposed workers. A slight excess of miscarriages among the wives of the exposed workers was found, but could not conclusively relate to the exposures. The author suggests that TDA and DNT may adversely affect the male reproductive system. He recommends that increase maintenance and cleanup effects be implemented, that the use of protective clothing be continued, and that a medical follow up program for exposed employees be instituted.
