W. F. FE3 |2 1974 AIA-54 N.W.. Washington. D.C. 20C36 {202) 223-48S5 naiP February 7, 19 7 4 In letter to Barry Castler.an, Center for Science in the Public Interest, dated Jan. 31 regarding CSPI call to ban use of asbestos cement pipe in drinking water systems (NEWS AND NOTES, 1/21/74), EPA Administrator Russell E. Train wrote: "While prudence in the public interest supports our current enforce ment posture, the medical literature does not support nor refute the thesis that ingested asbestos fibers are harmful. Feeding . studies have utilized massive quantities of asbestos far in excess of those that may be present in water and, even then, no incontrovertible data has been obtained. There is no agreement among workers on the methodology to be used to examine samples for fibers and neither is there agreement concerning which fibers are medically important.... Thus, while it is generally accepted that industrial exposure to air-borne asbestos is harm ful, this cannot be said with certainty of exposure to ingested asbestos. As a consequence, there does not appear to be evidence to support the action you have requested". In letter to Editor, Time magazine, following article in Jan. 28 issue, "Death From Dust", AIA/NA stated following: "The article, rDeath from Dust*, January 28, describing conditions at an asbestos insula tion plant in Tyler, Texas, should not be viewed as reflective of the situation exis ting in the vast majority of asbestos manu facturing plants in the United States. For many years, the industry has recognized the potential serious health hazards of ex cessive asbestos inhalation and has installed sophisticated control equipment and instituted improved work practices to reduce dust concen trations to acceptable levels so as to provide a safe and healthy working environment for industry employees. In addition, the asbestos industry throughout the world is conducting, sponsoring, or cooperating in extensive medical and technical research to 1a rr. ever, move about the health hazards of asbestos and the means for. their control." 0 i -OTOE2 3 AIA-54 Opinion survey of more than 3,000 adults as representative sample of U. S. population conducted by Environmental Protection Aaencv revealed sewage treatment, industrial air pollution control, and solid waste improvement, in that order, as prime environmental problems. EP.V s Donut-' "'irector John ?. Quarles in recent Boston speech advised EPA's work in protect ing and improving the environment does not impince significant ly on energy crisis and is net being shaved dour by it. "Da ar in fact, moving ahead without breaking stride,'' b.e said. Pro posed EPA budget for 1975 includes request for increase of $215M to total of $731M in operating funds. .'lost of the increase will be spent on energy research. Fourteen members of AIA/::.V s Technical Committee met in Newark, N. J., Feb. 6. The meeting was also attended by AXA/NA President John Marsh and Executive Director R. H. Mereness. Committee Chairman Ed .Fenner, JohnsManville, reviewed present OSKA asbestos standard and parceled out assignments to Committee members for preparation of suggested revision of standard which will be submitted to OSHA later in year. Environmental Defense Fund (EDF) filed suit last December in ' U.S. District Court claiming proposed EPA effluent standards for a toxic substance were inadequate and asked that 25 other substances, including asbestos, be considered. EDF was joined in suit by Natural Resources Defense Council (NRDC), National Audubon Society, and Businessmen for the Public Interest. No court action on suit has been""scheduled. Next public hearing on standards will be April 8. Meeting was held Jan. 10 among officials of Council on Environmental Quality (CEQ), EPA, HEW, and Mount Sinai School of Medicine to prepare Federal recommendation to governors and mayors of states bordering Lake Superior regarding drinking waters. CEQ and EPA officials recommend asbestos levels in water supplies be reduced and that Federal Government provide financial assistance for development of treatment facilities. It is under stood recommendation is under review by Office of Management and Budget (OMB) which must approve financial part of recommendation before further action can be taken.

WHO further concluded that the available evidence does not indicate a hazard from ingesting the infinitesimal quantities of asbestos which have been found in water, food, or drugs. A conference of more than 125 scientists from 13 nations meeting in Durham, North Carolina this past November to discuss possible risk to the general public from ingestion of asbestos reported no specific relatable conclusions. With regard to so-called neighborhood and household cases of mesothelioma, it may be pointed out that in the huge chrysotile asbestos-producing region of Quebec, not a single case of mesothelioma has ever been discovered, despite intensive investigations, in the household of an asbestos miner or in the neighborhood of an asbestos mine or mill. In the United States, only four "household'' mesotheliomas have been discovered. Literature is incon clusive as to the cause or causes of mesotheliomas. Because of the long suras vh i.eh led :nncy para on o r me naneas ?, the cases rare' oucurr `S'C5: AIA-54 rage ago at a time when neither the industry nor the medical profession knew very much about asbestos-related disease or the means for its control. Today, sophisticated dust control equipment and handling techniques virtually eliminate excess ive dust exposure attributed to asbestos-related disease. It is not surprising nor should it be alarming that very snail quantities of asbestos are to be found in ambient air and water. Asbestos is ubiquitous in our environment. it exists naturally in small, though detectable, amounts in serpentine rock formations throughout the world and is constantly being released into the atmosphere through erosion by wind and water. Asbestos is natural to our environment and -- as analysis of dated ice from the polar caps has re vealed -- has been for thousands or even millions of years. Man evolved into his present form in an atmosphere containing a natural background of asbestos, both in the air he breathed and in the water he drank. Today's atmospheric levels of asbestos are considered by the scientific community to be . only marginally higher than in the distant past, a fact not to cause fear. . In the case of asbestos-containing filters, research conducted by independent investigators and by the Food and Drug Admini stration has shown no correlation between the use of asbestos filters and the presence of asbestos fibers in the finished product. In fact, the FDA found that an asbestos filter is an excellent medium for removing asbestos fibers that mayhave been present in the pre-filtered solutionl On the talc question, the theories of Merliss have been criticized. Animal injection experiments conducted by Dr. William Smith of Fairleigh-Dickinson University using asbestos-containing talc have produced no gastrointestinal tumors in the test animals. While Ms. Hunter placed considerable emphasis on the asbestos migration study, of Cunningham and Pontefract, it misleading, at the least, that no mention was made of the studies of Swinburn, Smith, Davis, or Bonser and Clayton, all of whom directly fed asbestos in large quantities to test animals without being able to produce a single tumor of any type. is V7hile we can sympathize with Ms. Hunter's concern over asbestos because of its problems in the occupational setting, we do not feel that it is ir. the best interest of the public to raise fears and speculation unjustified by known facts and contradicted by major national and international health bodies. 0 : 02 AIA-54 Pace The asbestos .Indus cry is v;all aware of th e risk to health excessive dust and has made available to employees effect oust-eliminating or protective equipment, and it continue iurer.sive research into the asbestos-heal th relationship. Sincerely, Executive Director 3:-ototkC" ASSEiTOS-COVmO MACHINERY AT TYIER, TEXAS FACTORY Death from Dust When the Pittsburgh Corning Cor poration closed its asbestos insulation plant in Tyler, Texas, two years ago, it did an unusually thorough job of clean ing up after itself. Some 60 workers spent a week scraping asbestos waste from ma chinery and depositing it in a nearby dump. Then another crew took over. Ceilings and walls were steam cleaned. Every piece of equipment in sight was scrubbed down; some machinery was disassembled and shipped to P.C.C.*s home office in Pittsburgh. What was left was cut up and buried. When the craw finished, all that remained of the plant were two dilapidated wooden buildings that had once seen service as Army bar racks during World War EL P C.C.'s scorched-earth policy has left few visible reminders of the facto ry's 17 years in Tyler. But the scan from the plant's presence will not soon dis appear. While producing insulation for the boilers and pipes of naval ships, workers in the plant were exposed to enormous quantities of asbestos dust, which, once inhaled, never leaves the lungs. Now, based on previous ex perience with asbestos-caused diseases, medical experts estimate that as many as 300 of the S69 employed at the plant since 1954 will die of asbestosis <a per manent and often progressive scarring of lung tissue from inhaled asbestos fibers), lung cancer or cancers of the co lon. rectum or stomach. Their deaths should come as no sur prise to either company or Government officials. Doctors have long suspected that asbestos dust is hazardous: there has beer, ample documentation of increased in, `L'-icc of lung disease and cancers ;r. - people exposed to the mineral. A i c.'.: :v as lyol. Dr. Irving Selikotf. 59. ' v.*x York's Mount Sinai Hospital. and Dr. E. Cuyler Hammond, 61, of the American Cancer Society, confirmed the deadly relationship in studies of workers at a Paterson, NJ., asbestos plant. They documented their work in scientific papers and meetings. They aiso showed that even small quantities of asbestos fiber could be lethal Seli- koff studied a woman who died of meso thelioma, a cancer ofthe membrane that covers the lungs and lines the chest and abdomen. The Woman's only contact with asbestos came when she washed the clothing of her husband, who worked in an asbestos plant After the work by Selikoff and oth ers, P.C.C. officials ordered a study of the asbestos-dust hazard at Tyler in 1963. The report seriously underestimat ed the hazard. A 1966 dust survey found asbestos levels above recommended thresholds in many areas of the plant and a 1967 survey by the US. Public Health Service's Division of Occupa tional Health confirmed that the levels were high, but did not warn ofthe health hazard. After a Labor Department study two years later reported the same con ditions. respirators were issued to work ers in the plant's dustiest areas. But, ac cording to workers, at no time did P.C.C. officials tell them that they were exposed to a health hazard. "I even had one tell me that stuff, asbestos, is good for you." says J.C. Yandle. 48. a former employ ee. "He said you could eat it." Silent Violence. It was not until a 1970 law created the National Institute for Occupational Safety and Health (nioshH-and gave the Labor Depart ment's Occupational Safety and Health Administration (osir \ > the authority to enforce compliance with asbestos stan dards--that thin;> began to happen. In 1971 a niosii team visited Tyler, con firmed the of the dust levels, and emphasized the extraordinary haz ard. The team^Ail^A--5^4y ex amples of poof h^grenff pAeuctk: the company lunchroom was close to the production area and workers were us ing compressed-air hoses to blow dust off each other (and thus spreading it about), and the company was selling burlap bags contaminated with asbestos. MOSH promptly notified osha, which inspected the plant, fined P.C.C. S210. and gave it four months to come up to standards. When a reinspection showed that the company still had not installed necessary dust-control equipment, osha fined it S7.990 and promised further ac tion. Forced to make a decision. P.C.C. opted to close the plant. It cited economic as well as environmental reasons. The closing should help protect cit izens of Tyler from any further nsk of contracting asbestosis. But it will do lit tle to help those already exposed to the asbestos dust. Asbestosis and related cancers may not develop until 30 years after exposure to the particles, but once they do, they are painful and often fa taL "He hurt with every breath he took, because his lungs were tom and scarred on the inside from breathing asbestos . fibers,'* said Mrs. Robert Thomas of her husband, who died five months ago. Steve Wodka, 24, of the Oil. Chem ical and Atomic Workers Onion, which represented the Tyler plant's labor force, charges P.C.C. with negligence, a form of "silent violence." One group of for mer employees is suing P.C.C. for S100 million in damages: some individuals are also bringing SI million suits against the Government for failing to protect them. But neither the suits nor any belated medical care that the workers may now receive are likely to alter the odds against their survival. Now that they have been exposed to asbestos, the deck is stacked. Prescription By Computer Properly programmed, the comput er can plot the trajectory of a rocket, keep track of a store's inventory, cor relate census data and help predict weather more accurately. But can it be trusted to make the kinds of life-anddeath decisions that doctors do? The an swer may be yes. according to a team of scientists from Massachusetts Insti tute ofTechnology and Tufts-New Eng land Medical Center in Boston. The researchers report in the American Jour nal of Medicine that they have taught a computer to exercise virtually the same clinical judgment that a physician must use in choosing a form of treatment. In the process, they have learned more about how doctors make such decisions When the researchers began try ing to write a decision-making computer program three years ago. says Dr. Wil liam Schwarr:. chairman of the depart ment of medicine at Tufts University 01-0205233 rtv* JANUARY 23. 1S>X -''< i't .
