INTRODUCTION 1 A recent report by P*tter*oi. concluded from basic msterUl belance end geochemical consideration* that sen a* en Industrial animal he* eeverely B contaminated his environment end le suffering Iced Insult one hundred tlees greater then that present during his blologicel evolution. The report further B concluded that this level of insult, because It was sustained lna period too v*-*'V B B P short for evolutionary adjustment, is a danger to the well-being of e large portion of our population. Such widespread environmental contamination uns regarded ee particularly serious because it is cumulative end cannot be eeelly reduced should e critical level be reached. The above conclusions are in contradiction to a considerable array - B of scientific opinion that has developed from extensive work in lead toxicology and pharmacology. In general, the *o*t prominent workers have concluded I 1) Br .- y" that prisltive can suffered lead insult no less than one-half that presently ' r experienced by industrial sen, 2) that there ie a well-defined threshold value V fl of lead insult below which nan can exist indefinitely without ham, end 3) that fl the present '"normal" body burden (aa measured by the lead content of blood) of about one-third the threshold value allows an adequate margin of safety. G' B Patterson's approach to evaluating the implications of lead con tamination in Mn'i environment was largely tchoretical, and becauaa there is not sufficient empirical evidence available to either confirm or refute his argument the controversy remains unresolved. Pie purpose of this proposal is to outline a research pragma for the development and application of modern maas pectrometrlc and radioisotope analysts techniques in order to Identify tha MUlijftg WBW.m'W.u UJ*. m, r.cmfWP^ JJ .,, I 9 9 9 9 B 9 fp 1| 9 - 9 9 I 9 1 Isotopes, Inc. 1*2 sources of lead in sum's environment, to compare the present environment with environments of tha pa at and to. elucidate tha mechanisms by vhich lead say become available for biological assimilation.

TECHNICAL DISCISSION The Ceochenlatrv of Lead and the Environmental Health of Min Lead occurs In nature as a dispersed eleoent in various geological ertviroresents and, In addition, is coeesonly found highly concentrated in the font of ore deposits. Lead is well known for its toxicity, but as a dispersed element it la unlikely to be hamful because it is present only in very low concentrations to vdiich nan has adapted during the course of his biological evolution. When lead Is encountered in high concentration, however, it can be harmful and nan oust avoid rnvironaenta characterized by high lead concentrations whether such environments be natural or a product of Industrial coutaairvstion. Tlgure 1. shows sonc of the routes by Uilch lead nay becoae available to ban fro* the primary sources in bvdro. V and nines. bedrock breaks down to form soil. During the process, Soce of the lead of the parent rock rnu 1m in the soil and s o b* is dissolved in ground water which *ay eventually enter into streams. Tart of the lead results from the radioactive decay of radon gas. It, therefore, nay be expected to have a very different distribution fron dissolved lead inasmuch as part of it escapes into the atisosphere and later returns as natural fallout in rain. Lika several trace elements lead becomes concentrated in the organic material which forma coal. Thus when coal la mined and burned lead My become available to aan by a direct t ransfornot ton of the bedrock. That this nay be a potent source of lead Is Indicated l>y result* of Ih* "Trl City Lead Study" tiitrh Indicated Such higher sta>*phr|c lead ruwentrat Ions In the winter In Chicago than could be attributed to automobile r.'susts, lacking a positive beans of identifying lead frum different sources the author of this st>dy could only j. 1 'vat-- B 3 I I I 1 I ;| a I I I I B B 1 peculate that th lead originated In coal fly *h. Because geologic processes leading to the formation of coal are very different froa thoee leading to hydro thermal ore depoalts, Identification of lead froa theee different sources by lso- topic characterisation aay be poeelblt* . . Hoit of the lead In mo 's present environment comes froa nines. It enters the environment as various industrial products ranging froa storage batteries to insecticides and lead alkyla In gasoline*. If all of the lead In these various products were In fset available to sen there would no doubt be greet cause for concern. However, auch of the lead in lead products enter* the environment in inert fora*. It is known for example, that Much of the lead froa automobile exhausts Is found In relatively large particles which fall out rapidly and become part of the soil. As long as food Is ioported froa country areas the level of Iced In roadside toil* le not likely to be sn Important en vironmental health factor. On the other hand, Material In the subolcron range may stay In the air for extended periods, be breethed In and have a high probability of absorption in the body. Thus there sty be available and non-available fraction* of the sane Material, in general. Iced which persists in the atnosphere for some Tlae, or finds Its *y Into soil and water is most likely to be available to plants and to Mn. , Hot all teed which is available for entry Into nan Is hamful because It nay enter In a fra which la absorbed with low efficiency.

The use of lead Isotopic characterisation la a scans of Identifying the geochemical and biochemical pathways followed by lead to and through an, depends on the existence of natural Isotopic variations. The extent to which useful isotopic distinctions exist end the principles thich explain their origin ere discussed In the following section. The Oris In of Iaotoolc Varlatlona In Lead , Variations In Isotopic sbundancea occur widely in nature and In general stem froa two distinct mechanisms. The first concerns the thcrBodynamical properties of isotopic com pounds in chemical, physlochemlcal or biochemical process. Since the reaction kinetics are mess dependent, s lighter Isotope will react sore favorably than a heavier one In the sase reaction. The differences are sore marked In the lighter elements, in particular in hydrogen, capbon, nitrogen and oxygen, th biological tissue building elements. The second source of isotopic abundance variation occur* where an existing isotope Is sited with a daughter product of a radioactive decay aeries. ft>taslu*r-40, for Instance, decays to argon-40 and changes the argon J6i3i40 ratio with tine. Of particular Interest to the present discussion is the contribution to the world's lead Inventory by the decay of the unstable elements uranium aix) thorium. Common lead la found to comprise a mlsture of four stable Isotopes, r - - ^ 'A.V1.V;; "->w.f\cx3^tVis"-J".-' ` 't'`-:M'ri` ,. PMgPilPPPlig ss&rviSj&J *7 * &>- . , V-,' '1s>.

There are also as many as sixteen different a radioactive lead Isotopes known, but the principal one pertinent to thla dle- cuaalon la Pb-210, also knovn as Radius D. l Lead-204 is not knovn to have been foraed by any natural decay or any a other nuclear reaction. It, thus, constitutes a aeaaure of the original lead which was foraed d>en the elaaenta were formed, eoaetlaee known at oriaeval lead. a The laotopic ratio of Coaron Usd mined today results fro# the addition to primeval lead of radiogenic lead, FV204, Pb-207, and FV20R, forced froa tha decay a of uranium and thorlua. figure (2), (3), and (4) shov the decay schemes for tha a three radioactive families resulting In the stable isotopes of lead. The half* Uvea of the parents, 0-214, L-235, and Th-232, being the longest in each aeries, determine the ultimate retea ob fulldup of the radiogenic isotopes. In the earth's crust ss a tdwole, PV20* and th-204 are bsing produced at about tha same rata at a tha present time, while IV2u7 is being produced at a much slower rate because of the low abundance of 17-233. In early geological time, however, when 17-235 ms a auch core abundant, IV207 wsa being formed mors rapidly than IV204. a The differences in the laotopic ratios of common lead ore My be, therefore, attributable to the manner of the addition of the radiogenic lead to a the primeval lead. 1.

Th foregoing causes nay becooe combined, In any proportion, to sake new ora bodies in a variety of geological processes. . The existence of th isotopic abundance ratloa haa bean widely ueed to determine the history of lead ore depoalta, mostly galenaa, and such has been published discussing the possible interpretation of the considerable number of measurements in the literature. It la, however, the fact, and the characteristics of, these variations In major industrial lead ore areas that are pertinent to the present discussion. One of the prise objectives of the proposed study Is to differentiate in nan and his environment between leed derived froa local natural sources and that from distant areas via Industrial sources and pathways. To achieve this, it must first be demonstrated that tha Isotopic ratios of lead In local soils and ground voters can be distinguished fro* lead derived froa the major industrial areas. This would appear to be clearly possible In certain areas. In others the range froa the separate sources asy overlap such that definitive results are Impossible. It is the prleoiy purpose of the Initial investigation under this project to define the extent to which the Identification of specific sources Is possible in the present urban scene. An additional parameter which My prove to be a valuable tool to characterise lead in an and his environment is the specific activity of tha radioactive Jb-210. leads associated with little residual 0*231, euch at Industrial load, would contain little IV210. Soils end groundwaters on the other hand should contain considerable quantities derived froa th* 0-23S in the weathered bedrock. This could be a useful indicator of whether or not tha lead in plants is soil or atmosphere derived. hllW IM'M-'fS -ini.w.SM.) s iiiu m sw Natural Variation* of lead Iaotoot Cosoosltlon Aa a reault of tha factor* discussed above, significant variation la lead- isotope abundance* are observed in load source# from different geocheoical s backgrounds* Table 1 abow* a aelacted Hat of lead aaaplaa froa varlou* Mining B districts to eMphasiit tha great range In coBpotltlon.

Although such experience has been gained, (to a large extent by Isotopes, Inc. personnel) in measuring lead isotope rstloa, in measuring low concent rat ion of lead by isotope dilution, and In neasurlrg low levels of 1VJ10 radioactivity, the problems associated with the ultrs-*icroanalysls required fur environmental ssrplrs sust be approached with care and thoroughness not rocmonly exercised In routine trace analysis.

Aa a reeult of experimental design studies undertaken in Phase I, at least two sreas in th* Sew York City area will be chosen for environmental sampling. An etteapt will be made to identify and characterise primary source* of lead such as bedrock and soli*, coal and Fly-ash, lead alkyls In gasoline, and tobacco. SacVground information on the *4-*ple* analysed will be studied In order to understand the origin of the leutoplc c^eposltloh observed. la general th* lead In primary aourcet is not available to man.

A third aspect of the pilot studies will Include Isotopic charac ter!lat Ion of human saaples Including bone, teeth, blood, and urine to determine the relation between available environmental lead and that actually found In sen himself. In both the selection of sample type and procurement of saaples of human material guidance and cooperation will be sought from experts In lead biochemistry and toxlcologr. To place the results of the environmental sampling program in historical perspective It Is Important to establish the feasibility of using tree rings, soil" pro flies, snd sedimentary layers as records of changing levels of environ mental lead. Lead Isotope studies of tree rings are particularly important because relatively hit* lead concentration in outer tree rir^s has been used as prlna facie evidence of severe environmental contamination. The validity of these conclusions cannot be accepted unless It can be shown that the lead in the tone* of high concentration I* isotoplcally different froo the leed in the bedrock and soli and the seme as that in the atmosphere. Our meaeursmentt will be capable of establishing these important relationships. It is anticipated that correlative environmental studies will be underway during the tie period of these 11. Lccherge of in format ion with these programs and Isotopic analysis of significant sacples will enhance the value of the whole research project, because the isotopic tracer technique may be especially valuable In Investigations of lead metabolls* In blojegicet system* close attention will be given to the development of cooperative research programs. ! i j.
