I. ciuPont do womours and Company Organic Chemicals Department Wilxuri--fcon Qt Delaware Dear Mr. Emsberger: As I indicated I an writing to being you up to date on the develop ment or the experimental work in tho Laboratory on the inhalation of* lead, and on certain aspects of the contamination of* the atmosphere of* cities (especially) with the exhausts of automobiles, with particular reference to load* In a liner?}sicn of the tempo of the inhalation experiments with repro aentat ive s of Ethyl Corporation, the conclusion was arrived at that these experiments should bo expedited within certain reasonable limits, and I was authorised to proceed to that end* Accordingly, v;e have made plans to duplicate the respiratory chamber in the,room in which the first one is .installed and work is under way for that purpose* Scene remodeling of z -e room was required* Che result will be that we can carry on. the work with two subjects at nnco* Ir. addition, a smaller chamber ns no inn; provided in another part of tine building (on tine same floor) for doing the preparatory 'work required to provide reliable experimental conditions for further Investigation* In certain respects this will be a -ore economical rrav to work, but of coin*so 'the cost will bo creator per poor* 1 realise that you have accepted no responsibility for the Increased rate of expenditure involved in the additional work projected, and it is not my intention to involve your Company in this situation to any extent that goes beyond -oup wishes* On the other hand --cm should be aware of the situation, and both.of ua need to face the fact that there will bo no automatic means of allocating the expense of the work being done hereafter, Tho expense of revamping and adding to the equipment has . begun, and it Viill appear in the account for tho third quarter of the year* Therefore, I shall need to do something about it before long. As a way out of the difficult:/, I suggest that it might be satisfactory for you and your associates to decide and to Instruct me on the .maximum cum (regardless of the total cost of tho job) which you are prepared to appropriate for th3 job this year* '.'ou can reconsider the matter from year to year, on the basis of what is being accomplished and what you consider to bo its relative Importance to you. You will K t 0003230 Hr. ;i.

Another natter in which you are concerned relates to the . investigation of the lead in the atmosphere of cities, and particularly in that of Los -Angeles* '7 have been .studying this problem in a general way for sone tine, as ou know, and we have expended appreciable sums of our sponsors money on it. It is, I believe, a very necessary part of the information which the tetraethyl load industry requires for its reason able security* It is a double-barreled orobless, involving the lead in the air ana the extent of the absorption of this load by people* Vie have to :mrostigato the air on the one hand, and the quantitative evidences of the absorption of lean ou the part of the meat exposed segment'of the pc-pv.lntion, on the other, this problem, also, is the other side of t h e . crin, rc vide of which is tic 1aboratory investi.gation with which you are familiar* l-o oxbont of your our15.cipation in hois invent! ration is for "ou to cj.de* ''on have indicated previously that your Company did act -ich to participate in it, but I am not sure that I should accept '-hot ar a ftr.a.l or permanent answer, especially since I consider that it is not, necessarily, a wise decision* I speak of the wisdom of the decision only in the sons, that I suspect that if no such work were done, '"ou (and I too) would have Amocrtflot cause tc regret that It had yob soon* In m y case, no harm can come from my recalling the ratter to -cur attention -with the perspective that may be indicated by the recent (brand for cucu information In Los Aygelos* If v;e had had no inform ation. vc should bo on hie spot* Since we wave some satisfactory cafea we can ever core of tho. quest! one and avoid being pushed hate unprodr.ctivo work. A further case in point la that of the mis informal;!on wnich no soared :In vJLE lately* Since wo '-now that what was said was nonsense, vc could af"ord to take a philosophical attitude toward it* Otherwise wo vl"ht have been jockeyed into an embarrassing position* -ho are not under any immediate pressure except in Los Angeles, and I shall relate what we are doing there presently* however, we should proceed in our own way and time to obtain convincing information on this matter, and I nunpoet that your people will wish to provide some modest support for these observations and spread it out over some period of time*] In .Los Angelos we had anticipated doing some work independently. As it happened the Southern California Air Pollution Foundation approached us with the suggestion that we carry out an Investigation under their sponsorship. 7/e agreed to do so finally aftor exploring the situation with them on the basis of our studying the particulate material generally and not lead exclusively* This is being done in what I believe will turn out to be a satisfactory manner, and without putting undue emphasis on the atmospheric content of lead. Fhe Foundation is pav.ng for the job, except for the fact that we have obtained some local assistance, for our own convenience, from technical people in Stlyyl's San Bernardino Laboratory* >7e should find it most troublesome to do all of the fetching, carrying and manipulating, and; it seems fitting and to KE 0003231 Mr* M* L.
