L. r.teeher organic Chemicals iilrsington, Delaware Tatra Sthyl Lead Hn.~ rrd For some time I have been concerned. about the condition of health of the men emnloyed in the Tetra Lead Area. t have known for years th?t tn-re a re certain locations in the area where absorptions nre greeter than other locations. p<? hsve noted that many of the men employed on the f.till Floor develop symptoms of absorption nd even symptoms of intoxication. In order to develop specific facta in connection with the health picture of the individuals employed in the Tetra Ethyl Lead Area we have accumulated information /-.nd have tabulated this information covering one year. Part of this information vma used in a report we recently wrote discussing., conditions on the third floors of the buildings. As we pointed out in that report some further protective means are necessary to prevent the de velopment of cases of lead poisoning. In.our attempt to control the situation in the lead area we have employed the following mennss 1. the clinical examination of each work men very three weeks, 2. Aided by laboratory testa which have included smears of blood for the de termination of stipple cells \ 4 count of the red and white blood cella to determine the development o r --. tt eml a . t. :^ereiion teats upon men performing ench type of task repulred In the rrsm.

Of? have shown previously that from routine air coo* .'.-inations there ;ere' army times curing the pout year when the concent ration was above a safe worklnr level The attached table chows the number of times dur ing the past year that the air analyses for various loca tions m the lead area were above a safe working level. In the Blender la pnrtioulsr the concentration at various tinea has been three times what in considered safe, bmice, individuals employed in those locations during those periods could not help but absorb sufficient Ic-nd to pro duce symptoms of intoxication. ..t the aase time in the ''lender there re individuals who have shown by clinical examination and from the? laboratory and excretion teats that they heve severe lead, absorption and in otie or two instances lead Intoxication. yf 00077J6 3- Aa a result at thuaa findings something should be don to correct 'the condition In the present blender. There is no location In the entire lead area where we do not have clinical evidence of rather sever lead absorption. riB have charted in the attached table not only the high air analyses but also the number of men in' each location who nave shown objective-and subjective- symptom atology as well as high excretion/teats. <e nnv pointed out in the last column in the table the number of men who have - a combination of these tlndi.K-'fi, in other words the groupylleted in the last column could all be diagnosed as oases of mild lead poi~ , phouic, %-Aii diagnosis be made we could not re fute it. "Inca this picture discloses the fact that there r r--- twenty-four- nen sho have symptoms of alia lead intox ication believe consideration should be given to this subject m order to more adequately -protect the employees of ills area. imps .wnuca me d ic a l DmKmumt BXt ^ ___ ^ b ,l; .jaaw /< 030773' .......... >it 4\ mi v 4.4 .> ^ 4 Fv r Tlmem Hursiber of : Above Um *#ith vlloweble Objective Limit Oy:aptoe i .4- Humber of Man vith SubJeetive Symptoms dumber of Msn with High Sxoretlona Humber of im show ing &11 Pont Viva Finding 3rd floor w ui J StO floor' \* * J i 25 v> 10 'V: . c *.) & J 10 lb -.0 ' ? -;: 6 i W **S*.
