M. S. iadollet retired Johns-Nanville Asbestos Engineer visited rhe laboratory or. July 9th. He described sore con sulting work be is doing with Eairleigh Backauson University or. the effects of asbestos on bee lob. He personally obtained eer.ples of soft and harsh Arisons chrysc- cile fiber v:bicb were obtained at the ser.e location 20 feet apart. Tbe ends of the fiber were clipped end cere was taker. ontsninarion ccou: Tbe fiber was fiberized and o sample wbicb -..us all -100 nesb was obtained. Sarples cf soft and bereb material were injected into tbe threat and lungs of hanpsters. Mslignert tumors developed in all harps tars in jected with rhe harsh asbestos while no tumors developed in harvesters injected with soft asbestos. The experiments were repearedj and differenr hanpsters checked to give the sane re sult. Fluids of the rumors injected into healthy hanpsters re sulted in runorous growths. Mr. Headier also reports that a chemical compound called Cyrcnin has been found fully effective to cure the maglinenr tumors developed by the asbestos. He is following up the .rarer cf hydrat; indicating of what is harsh and what is soil fiber. The -aft __ber had a TGA weighr loss of 13.6 and sue aarsh fiber had a TG.. __ghr loss of 12.2 Johns-Hanville di; tha TGA work. Nor....nay Tiber runs in the 12 range whereas l_h fiber runs in tn_ 13.0 range. It is known that rhe harsher ur____ re and crocidclite are a grearer hazard than chrysorile. Nr. Badollet has hear-treated some of rhe soft I'-,, water hydra-dor. loss fiber to a point he hopes will be atom; _2.C. He wants ASABCC to run several TGA5s for him which v:e have agreed to do. Ha then, of course, will determine the affect cf rhe heat-treated fiber on hanpsters. c ASARCO ALV 0012427 ?/S/o5 i> o Z_l*l & yc: IT y IT3 S c ^ yc.u o* 1^^/a.c*#c 5 f<r/' r-\ ASARCO ALV 00124-28
