The desirability of s o bs such procedure wi alao nfarrad to at tha Daceaber 196$ Load Bycpoelua and at the Senate Bearings the following spring. It baa bean hoped that this could saorbev be incorporated Into the health examination portion of the rational Health array. The pattern of operation of this survey Bakes this lBpoetlble. Accordingly, the Casnltt-ee felt that s o d s study nethod s 1*1 1s t to that esployed In the three city study should be developed, and carried out at suitable Intervals. Ibis Gubcosaslttee sa foraed to under take the development and execution of such a etudy. This seating was held to consider exactly Wjat type of study would be desirable, and at vhat Intervals. 7he following conclusions vers reached. They are to be discussed by each neater with his colleagues and then reconsidered at a subsequent Meeting. 1. The general pattern of the three city study of using selected population groupe for biological aeasurenents and selected urban and suburban sites for air aeaeurcarnt# of lead aeaae useful. S. A andfrer of laprcrvesante can be aade froa the first study* These are specified below. 3. The study ahould be repeated at about J year Intervals. The first study should be done In 1967*66. V. The original three cities should be reetudled sad also Bev York, Chicago and Washington. J. Six to eight *e ronetrio site# should be used la each elty. Za the three etttee previously done, three or four of the original sites should be retained. Especially la loe Angeles end Cin cinnati aore contrast In sir lead levels should be eou^it, since the vide range of the fblladelpfcla asaplet In the last study was ad vantagecate. It la act necessary to stay with In the city limits. A vide range of air lead levels le of aore interest than the political boundaries. |f `S: * 6. Air lead Htiuncnti could be pooled for analysis to ft considerable extent o thet liboratory vork could be reduced. The daily eaaplee for each station could be analysed w#kly or oocthly. Btu4y of particle 1m distribution of lead at each station at rack mmo o would be ft desirable addition to the arrcortrier. 7. Ro chaos# In laboratory aethods for air or biologic sasple# is advocated. Blood aanplee only rhould br obtainrd oo people. Crloe lrad level# arc of lrtt valus and add llttl# or nothing to th lnforaatloo ohtalord. 8. The uar of rrlrctrd population groups ahould br continued, fewer, aorr u&lfora group# would br advaatage<xis. Urban polio* ahould br studied in each city aa before. Thla will allow for coaparlaon between the three city study and future studlee. It la not clear to wbat extent police cao be eaepered between cities. Here loforaatioo oo the nature of their work * particularly the proportion of tlar on foot and in vehicle# would br deetreble. 9> Other group# prevloualy uard ahould not be repeated. In aelactlng Dev group* enthrals ahould br placed cs slsiiarlty fra# place to place and froa tin* to tine eo that future etudle# can aalntaia ecaparabllity without reeortlng to keeping track of individual persons. Also dee treble le a 11a! tattoo to prcple who live and work in the saas area. Suggested useful group# are (1) poetoen froa local poet office# close to the teronetrle stations. (2) bousevire# obtained through PIA or church group#, and (3) telephone operator# fren local exchange#. Children should not be used. 10. The cusher of lndlvlduel# required la each group abruld be determined by analysis of variance applied to existing data, pectally the three city study arterial. 11. Thar# was oo agreement on whether the study should be don# by eereral groupe coordinating, a# before, or by one contractor, further considerations on this point are deelrable.:, / vvf
