The first 61811 reported is which asbestos vn suspected f affecting the human lung were in 1900. In 1930 textile plants became concerned although the pathology was poorly described. The Tlrst hard look at the proxies concerned asbestos!* and the second, the cancer producing proclivity resulting in bronchogenic cancer. Aebestoeis is associated with long-tise exposure in which the lung shews scarring and inflammation. Biological effects show interference of movement of oxygen froa gas phase of the lung to liquid phase in the blood. Measurement of this 02 movement is indicative of progress of scarring of the lung. Asbestosis results in lessening of elasticity of the lung and destroys ths blood vessels of the lung, T ' The threshold Unit value or aVriaua allowable concerttratlon of dust particles has been 3 million particles per cubic foot of air, of particles less than 10 morons in dlaneter. This provisional licit is now inadequate and is being changed. n Oreat Britain in 1930 it was found that the incidence of lung cancer was higher in asbestos workers suffering froa asbestosis than in the non-asbestos workers. The asbestos producers in Canada had organised a study at the same tine involving the mill workers of the Thetford area.. This original-study failed to show any undue frequency of lung ' cancer. However, it was shown that the only study data available were froa relatively incosplete and sketchy death certificates. This resulted in aandatory death certificate data showing detailed contrasting causes. Textile and friction saterial workers deaths were isolated,* with both types showing earlier deaths than the rest of the population. Textile workers, because of high dustiness in textile plants, - JAN 7 'SI 7i06 fiFSI --a <*0Ct502 2013384805 PA<3. 025 t>&M BTiAtm HltgigT 7VVU I* 7HH UlUm* :wmiU HHMdfcKS l WB-W ggi g^S ** * '.sn Hr.

A thin seabrane covering the lung is the taeicthelU. Abnormal calcification of the cells of the lining surface results in oeiotheiioaa, classified as a rare turner under ordinary circumstances. As few as two or three are seen in a lifetime by the average physician cad only 1 in every 1000 lung tusnors is a aesetheliosa. But, in South African eroeidolite and aaasite workers, detens of Besotheliomas have teen found. Residents of the area, such as voaen not working with asbestos, have been found to be victims. Roads, in the crocldollte areas, contain fibers which filter through ear windows are among the causative agents suspect. Hesothelictt&s are very rarely associated with chrysotile asbestos fibers for reasons not yet known. It has been demonstrated that bronchogenic cancer is ten* tines as high in insulation workers as for e$ual age groups not esployed in this type of work. Workers in the insulation trades exposed twenty or more years and who are cigarette sacksrs, are SO tines nore susceptible than those net employed in the insulation industry and are non-seekers. Tibsrs which stay in the lung and becone tissue-coated are called "asbestos bodies". These are found in the lungs of the bulk of the population to a greater or lesser degree. She tern nay be aislesding, however, In that, the core of the asbestos body Bay be froa a source other than asbestos, such as a aan&ade fiber, talc, or the like. Research is in progress to identify the origin of the bodies" and to correlate this with disease end causes of death. (C) Organising and Engineering for Dust Control S. M.

Ho attempt ha* been r.de to differentiate between type* of aabectoi, hind* of application, etc. It is essential that the American Textile Institute keep informed of this legislation. The Threshold limit Value of Asbestos Sust legislation is a forerunner to statutory change# in the present law*. It will reduce the current maximum value in industrial air from less than 5 million particles per cubic foot of air to less than 2 million particle* per cubic foot of air. Impingement dust particle count method* have been found to be leas efficient than merbran* filters and new methods of establishing particle counts sre to be used which are entirely different than those used before. Orest Britain ha* introduced new threshold limits which are far more stringent than those used in the United States* The Unite* States has proposed 12 fibers per cc over 5 microns, maximum. For ehrysettle and aooslte, Orest Britain has proposed for air, 2 fibers per co and not more than 10 fibers per cc. Where b fiber* per cc, inspector* will insist standard* be improved. Vnere 10 cc or store, at&sspher* will be con sidered dangerous and the conditions will be held unworkable. For crocidelite, Great Britain has proposed limit* of O.l of those for chryeotil* and aaeslta. 2a the Unite* States, four potentially damaging law suits are is litigation at present, which could seriously effect the asbestos industry.

R. P, Oagnon October 11, 195S It was decided to repeat the round-robin teat program but to eliminate the test operator is a major variable. One man, familiar with both tests, will tour the member laboratories vith teat standards end teat aamplea and inatruct and observe the teat procedures at each teat location* A representative of Sell Mines will b uaed for this work Magnetite standards of the old P?A, Bureau .of Standard* material, hae bean uaed up. Kev atandarde are being cheeked against 29A and will be lasued when tested. The problem of determining objectionable grit in spinning fibers is being investigated by using wet cyclone separation methods. Results show good separation of the rejects' froa the long fiber, but it has not been determined that the long fiber is an acceptable spinning fiber by the trade. The textile companies will supply the flocalttes with samples of objectionable portions of spinning fiber, so that the test may be more closely .controlled. There is a need for more attention to the dust problem in fiber packaging such as bagging for overseas and domestie.handling. A tub-eomoittea for color testing is required to sore fully Qualify terns, cheek new sculpsent, ad In vestigate calibrating standards. CSS/1* cos H.J. Kassel L.C. Piute v E.A. Ferrell/ K.V.
