title: Cancer mortality and asbestos deposits.
abstract: Asbestos deposits are found in many parts of the United States. In this paper the question is asked: Is there an increase in risk from cancer associated with naturally-occurring asbestos? In an attempt to control for the urban effect, geographic gradient and socioeconomic class, each county in the United States with asbestos deposits was matched for percent of area that was urban and for median years in school with two nearby counties that did not have known asbestos deposits. The study of cancer mortality rates in these matched counties provides no evidence that naturally-occurring asbestos is a great hazard to the general population of counties with asbestos depostis.
