Selikoff and his colleagues at the Division of Environmental Medi- cine at Mount Sinai Hospital the chance that an asbestos worker will get lung cancer is seven or eight times as great as for the population as a whole If he also smokes cigarettes he is 92 times more likely to contract cancer than the average man The exact link between as- bestos and canceirs not known It is believed that since asbestos has the excellent property of absorbing other chemicals onto its surface it is often used a filter it may once taken into the lung hold causing chemicals in contact with cells for just that extra amount of time needed to set the cells on their rampage of wild uncontrolled growth Normally the cleaning process of the lungs quickly ejects such causing material That most of us have our share of asbestos was indicated in tests conducted by Dr. Selikoff's group In a series of consecutive autopsies the tiny asbestos fibers a million to the inch when laid side by side were found in the lungs of 24 out of 28 New Yorkers Apparently once the fibers enter the lungs they stay there As evidence of the dangers attending asbestos has mounted new indications of its omnipresence have emerged The airof Manhattan tested far from a construction site contains six times as much asbestos as the air of Ridgewood N.J. The fibers may come from the brake linings of automobiles as well as from windborn construc- tion spray Two weeks ago Jerome Kretchmer the city's Environmental Protection Administrator called a press conference to say he had asked the Federal Department of Health Education and Welfare to investigate asbestos that his department had found in baby talcum powder Talcum like asbestos is a mineral and the two are often found together A week earlier it was revealed than an Italian maker of cloth had mixed asbestos with other fibers to take advantage of reduced import duty on fireresistant materials The cloth was tailored into coats and Dr. Selikoff's laboratory discovered that wearers of such coats move in a cloud of asbestos dust Numerous modern buildings that have already been sprayed with asbestos have large interior channels and chambers lined with the stuff Those channels frequently provide the return from conditioning so that the surfaces offer up fibers to the conditioned air Finally there is the asbestos time bomb All the sprayed buildings will be demolished in say 75 to 100 years As the wrecking balls smash the masonry and the girders are dismembered the air for miles around will be filled with a haze of asbestos dust Annual world asbestos production has increased from 500,000 tons in 1930 to more than 4 mil- lion tons today a nine rise It has pervaded almost every major manufactured product The City Council's ban on spray ing is the first move to stop the July snowfall and to get asbestos under control EARU L BELI Mr Ubeli la Science Editer for WCBS News New York Reproduced with permission of the copyright owner Further reproduction prohibited without permission
