||Some EPA libraries have a fiche copy filed under the call number shown.
||No histopathologic classification of observable mass performed. From later studies on other materials it has been learned that these would include: squamous cell carcinoma, benign epithelial papilloma, hyperkeratosis, acanthosis, and conditions of irritation having mono-nuclear cell invasion of tissue. It is estimated (from later studies) that at least 80% of observable masses would be classified as tumors (benign or malignant) with a great majority being benign epithelial papillomas.
||The quality of the documents listed in the Office of Toxic Substances database may not meet usual NTIS standards but are included to further the opportunity for the scientific and technical community to locate materials which may not be available elsewhere. The content is the responsibility of OTS. Prepared in cooperation with American Petroleum Inst., Washington, DC.
