Lead burning and the welding of alloys and painted piping should be done on the benches provided with exhausters. 33.

If working conditions are not signiricantly altered, asbestos exposure can lead to 17,000 deaths from lung cancer. 10.000 deaths from cancer of the pleura and peritoneum, and 10,000 deaths from asbestosis. according to projections by Dr.

This lead GE to seek understanding of the aoope, reproducibility, reliability and validity of the analytical procedures used by various investigators who reported finding PCB in concentrations as low as parts per billion.

Exposure to certain industrial chemicals can lead to cancer that possibly may not appear for 10 or more years, according to National Can cer Institute specialists.

Because time was of the essence, I suggested that we propose the 1 0 :1 ratio of ASTM Designation D2946-71T; 3. that we not try to redefine asbestos to specifically e x clude tremolite since assuredly this could only lead to a long-term technical and scientific debate; 4. that any presentation to the FDA or to the Bureau of Mines Symposium .which had been arranged at Vanderbilt's behest should concentrate on the medical evidence 'regarding the difference in biological effect of tremolite and other amphibole fibers; and, , 5. that we propose a single definition of c^^.crcial talc which would include all .types .of talc and, therefore, eliminate the need for differentiating between "pure" talc and talc (fibrous)-Tremolite as defined by the ACGIH.
