Stafford, ICI R. N. Wheeler, Union Carbide Corporation CPSC VINYL CHLORIDE STUDY IN RATS AND MICE In response to an informal request for information Dr. Robert Hehir of CPSC has sent the enclosed manuscript. While considerably improved over previous drafts, the authors relate the lung adenomas and car cinomas in mice to vinyl chloride, choosing to minimize the possible relationship to pneumonia. It is my understanding that the manuscript will be submitted to Toxicology & Applied Pharmacology. I'd appreciate any comments you might have. Sincerely yours, CMA 000423
