April 1, 1959 Mr. t. L. Zlegfeld, Secretary Lead Industries Associfttion 60 Seat 42nd Street lew Torfc 17, V. Y. Dear Mr. Zlegfeldt- Si .'V. -yc'SB4!' -O- Thank you for your letter of March 20th refirdiaf the fin- . tion of protecting the use of lead in color pifaesta from whet we feel ere unjustified restrictions. Tour letter raises the qnee* v tion that the chroaiun radical is often considered oontributory and a possible source of cancer* It is true that the basic chrome chemical pro dueinf industry has been investigated aloof the linen yon neat ion, but the sane thinf is not true of the chrosw chealcal een- uaiaf industries. Actually, there is considerable question about the hasards of chroad.ua toxicity at this source, >but when the chrom ium has been conrarted to the chroaate fora, I believe you will fled very little to justify any stigaa on this chroaiua conpound. f We are one of the basic producers of chrome chemicals, sad probably the larfcst consuaer in the world, and although we have handled Billions and millions of pounds of chroaiua in the fora ef Lead Chromate, we have never had a single case of cancer traceable to Lead Chroaate exposure. If this were not enough proof, we have' also never heard of s case in the plant of any of our customers for the Lead Chromate pigments, and I an sura that with thn Isrg# exposure the workmen would gnt at this point, that if it were a severe hetard, we would have heard of it. We know that certain chrone producing plants hav# had a bad experience, and that wan thn reason for the investigation, but the results have indicated that there is eoae intermediate fora la the producing of a chrome chemical not in the use of it, which aeeae te be at fault, but for aoae reason or other our pmeeees for producing chrome chemicals does not aaea to present the hamard, even nt thin point, that some other producers seen to have. It is this point which has been invnetigated, sad to my knowlndgn mo definitm eom- cluelome have been dratm. ? It is a far cry from the concentrated exposure that our workmen gnt,and our customers* workman get, to the expoenre ef the user who applies a paint film to seme surface.
