"Low iron chrysolite asbestos carries no ;' hazard of pulmonary carcinoma, mesothe- , .Jioma. or emphysema." Such a conclusion - was made from a recent independent . study of 100 asbestos workers conducted _ in Gila County. Ariz.. by Drs. Frank Prie* ser and Tom Jar\fis, experts in pulmonary' ^ medicine and pathology, respectively. "The hazard of asbestosis or silicosis is recognized as possible in extremely high J, dust concentrations, but this exposure is seldom experienced in present chrysolite ' asbestos milting operations in Arizona and il- never duplicated where the general public -is concerned." X. *' These studies were prompted by a re cent report by Dr. Irving SclikofT of the 'J Ml Sinai School of Medicine in New V - York City. In B.\ SelikolTs report, he con- j eluded that asbestos had definite links to ~~ lung cancer, asbestosis, and other lung ' " diseases. According to D. W. Jaquay, presidenL Jaquays Mining Corp.. "Much of the re cent asbestos scare publicity was mis-read -by government regulating agencies." Ja quay points out, "In the SclikofT study, two forms of asbestos--amosiie and cro* ridilite-which contain 40% iron, predomi nate as study sample." He also states (hat **by Dr. SeHkofTs generalizations, a whole - indusliyhas been condemned." < At the Jaquay opentions in Gila ' County, asbestos is of the chtysotile vari ety, containing less than 0.5% iron. Results from the Prieser-Jarifis study conclude, as - Jaquay points out, "no critical health haz ard exists in a chrysolite operation where . there isa normal dust control prograam " `-I v!
