The results of three research projects carried out over the last six years support the conclusion that emissions from brake lining wear are not a significant source of asbestos in the environment, says the Asbestos Informa tion Association/North America, in o pamphlet. When brakes are applied, the high heat of friction converts more than 99 percent of the asbestos in the lining to a non-fibrous, non-toxic material called fosteritc, it said. Total airborne emissions of free asbestos fiber from brake lining wear umount to about 2i tone each year for the United States, or less than one-half of one percent of the total particulate emissions in a city the size of Los A...-vie,, in a sini'le day. it avood.

Petition for stay of the effective date of the standard for occupational exposure to vinyl chloride was filed with the Secretary of Labor by the Society of the Plastics Industry, Inc.. on November 5. Primary ground for the petition is that respiratory protection requirements of the standard set by the Occupational Safety and Health Administration on October 4 "are beyond the compliance capabilities of the industry." according to the petition filed by SPI Counsel .lerome H. Heckman. Keller and Meckinan, Washington, D.C.

A supply company in Itasca, Illinois, was cited with failure to provide firefighting equipment, not controlling trip and fall hazards, having incomplete hollow-pan stairs, not guarding floor holes, and foiling to post emer gency phone numbers. The company argued that no such hazards existed. The Review Commission Judge agreed that the firm need not provide firefighting equipment because there was no fire hazard, but the affirm ed the stair and floor hole violations. The judge also slapped on a <100 penalty not originally sought by OSHA for the firm's failure to post the telephone numbers of doctors, a hospital, or ambulance services. He lull that the delay ir providing emergency medical treatment could imve Kcriou.- consequences.

Rock ville. Md. Automobiles, the re search firm has found, spread a troublesome layer of materials over the road. Rain then washes much of the pollution into the surface waters draining the area. For more than a year, Bio spherics teams have vacuumed blocked-off sections of the Capi tal Beltway and other area roads, and meticulously analyzed the debris. Among the findings: Counting all area highways, from Washington, D. C. out to the Beltway, 55 tons of pollut ants are dropped a day, nearly 20,000 tons a year. Private cars, which outnumber trucks five to one, account for most of the wastes. On the Capital Beltway alone, vehicles deposited 16 tons of sol id waste a day, nearly 6,000 tons a year. Laboratory analysis shows that the materials include as bestos from brake linings. ruP ber from tires, zinc from oil and tires, lead from gasoline, other heavy metals, and nitrogen and phosphorus compounds. Rain washes most of these pollutants from the highways, into storm- drains, and then into area streams where they degrade the quality of the water. Ot all the substances found in the roadway debris, asbestos is perhaps the most potentially hazardous. Nitrates and phos phates promote unsightly algal growth. Toxic materials may harm some forms of stream life. The bacterial content of the water is also increased. For hours following a rainstorm, the road runoff is almost as strong as municipal sewage in terms of many pollutants. The findings thus have identified another, heretofore unsuspected, source of Potomac pollution. ``Altogether, when the data for the Washington area are pro jected to the entire country, roadway pollution from cars be comes a critical national prob lem," according to Donald G. Shaheen, Biospherics' project manager. "Extrapolating to a national scale, 100 million cars and 20 million other vehicles deposit a staggering three and one half million tons of pollut ants a year on American high ways," he said. - I , *'W' Laser Measures Polymer's Molecular Weight The laser is aiding in the solution of another difficult scientific problem--measuring the molecular weight and size of polymer ma terials. Dr. Andrew Wims, of the analytical chemistry department, General Motors Research Laboratories, pioneered this method that helps chemists determine possible new applications of plastics and other polymers. Wims is shown aligning the laser source in the light-scattering photometer he designed and built To make the technique more widely available to the technical community, Wims is now helping to develop specifications for light scattering photometry that can be used with laser beams or other light sources. The standard test procedure is to be published by the American Society for Testing and Materials. Using the laser beam allows scientists to make more precise measurements of mo lecular weight than was possible with conventional mercury vapor lamps as the light source. * First Step Toward Offshore Nuclear Plants Atomic Energy Commission has docketed for review the ap plication to manufacture eight floating nuclear powerplants submitted by Offshore Power Systems, an enterprise of Westinghouse Electric Corp. and Tenneco Inc. This marks the first time that a standardized plant manufacturing application has been accepted for review under the AEC's new regulatory procedures, according to OPS president A. P. Zechella. Next step in the process will be an in-depth review with the AEC that is expected to last ap proximately years. Then a public hearing will be held on the manufacturing application. Final step will be the issuance of the license. OPS has already sold two 1.15 million kW units to Public Serv ice Electric & Gas Co., which plans to locate the plants about 2.8 miles off the coast of New Jersey.
