520 |a"The potential utility of monitoring neoplasia in fishes and their associated oncogenic viruses as sentinel animals for the early detection of waterborne environmental carcinogens was explored. Field epizootiological studies of Great Lakes coho salmon were made, and on increasing frequency of occurrence of thyroid hyperplasia (goiter) was found. Epizootiological studies strongly suggest that extrinsic environmental factors coupled with the low iodine environment are involved in the etiology, etc. of the disease. No evidence of virus was found in electron microscopic studies of the neoplastic thyroid tissues"--Summary, page 1.
