Cohort Mortality Study of North American industrial Sand Workers. II. Case-Referent Analysis of Lung Cancer and Silicosis Deaths

摘要

Background: A Cohort Mortality Study of 2670 men in nine North American industrial sand plants resulted in 83 deaths from lung cancer 20 or more years after hire (standardized mortality ratio 139) and 37 deaths from silicosis (including seven from silico-tuberculosis). The lung cancer excess was unrelated to duration of employment and not found in all plants.
