Review, Summarization, And Evaluation Of Literature To Support The Update And Revision Of Criteria Documents. II. Coke Oven Emissions.
NIOSH 1977 Sep:44 pages
The literature on coke oven emission hazards is reviewed. Emissions are identified, including benzene (71432), toluene (108883), xylene (1330207), and other aromatic compounds. Types of sampling equipment are evaluated, and techniques for separating coal-tar- pitch (8007452) volatiles are discussed. The epidemiological effects of volatiles are assessed. Rates of lung cancer and other cancers are compared with those of the general population. Potential carcinogens are cited. Correlation is made between bronchitis and employment in coke factories. Possible mechanisms by which carcinogens might be activated are discussed. Aerosol toxicity studies on animals are reviewed. Animal studies on skin carcinogenesis are presented. Engineering methods to control coal- tar emissions are discussed, as are methods for worker protection. The authors make recommendations for characterization of coke oven particulate emissions, for the identification and bioassay of potential carcinogens, for evaluating the health effects of noncarcinogenic gaseous and particulate components of emissions, and for monitoring daily coke oven effluent.
