January 12, 1933 Mr. F. E. V/orraser Lead Industries Association i|20 Lexington Avenue New 1'ork City Kew York Dear Mr, Wormseri I am not quite sure that I understand the Implications In your letter of January 3rd, in \diich you ask for a definition of lead poisoning, I was not aware that there was any question about the definition, and thus I wonder just what -you are trying to get at in raising the question* Prom ray po*nt of view, it would be entirely satisfactory to describe lead poisoning as an intoxication produced by lead. If, on the other hand, you are trying to get at a diagnostic description of lead poisoning ?/M.eh excludes every other possibility, then I must say you are in for trouble, There is no sign or group of signs or symptoms v/hich delimit lead intoxication, so far as X am aware. One may establish a reasonable diagnosis based on the three points: (l) history of exoosure to lead? (2) proof of exposure within the significant range, through lead 3analyses of the excreta, blood, or tissuesj and ( ) the existence of symptoms and signs characteristic of lead intoxication. . Perhaps I mis-understood your question. If so, I should be glad to give you any information which I can if you will make clear just what you wish. Very truly yours, RAKsIS K* 0014S74
