A single bout of lead intoxication (of the usual type) has little likelihood of leading to prolonged or permanent disability.

Did you know that the additives needed to replace lead are harmful, which lead is not.

Joseph Lead Co.

When a gasoline tank is filled, the vapor so replaced contains organic lead, and spillage with evaporation releases lead vapor to the air.

The reason is that lead glazes when used, are the result of firing lead and siliceous materials at a sufficiently high temperature to produce lead silicate.

Gilfillan (2) June 17, 1965 with lead.

If lead were to be found in his tissues.

he lead market.

Because of this essential characteristic, o the secondary Lead Industry has eaerged as an integral part of our total Lead structure.

In this connection I may ssy that we are all of us taking into the body approximately 0,25 mgs, of lead per day in the food, and that we are excreting an equivalent amount in the feces and in the urine, Under these conditions there is no progressive accumulation of lead, and poisoning does not take place, ibis is apparently true also at considerably higher levels of lead intake, and it is for this reason doubtless that lead poisoning does not oeeur within the limits of respiratory exposure that I have indicated.

If the micro,'-.rams of lead per litre are more than 200 or the micrograms of lead ner hour arc more than 8 , the employee is concidered to have absorbed too much lead.

It was ex plained to him that the Committee represented a cross section of manufacturers of metallic lead products such as lead pipe, sheet, solder, bearing metals, type' metals and other lead-tin alloys, also the manufacturers of lead pigments *uch as white leAd, rod lead, litharge, orange mineral, sublimed blue lead and tho lead chromates

Kehoe, the follov/ing conclusions are drawn:- 1) There is no reason to fear the existence of danger to the public health from the distribution and use of leaded gasoline; 2) Experimental evidence has indicated that the hazards of lead absorption fuom skin contact and inhalation of vapour from gasoline containing tetraethyl lead were practically negligible; 3) The lead exposure associated with the handling and dispensing of gasoline containing tetraethyl lead at service stations is negligible; 4) The lead exposure arising from prolonged employment inthe care and repair of automobiles using leaded gasoline for fuel may be sufficient to cause slight increase in the mean rate of urinary lead excretion, shown either in a greater lead output per unit time or in higher lead concentration.

As regards other countries in which leaded gasoline is distributed at the present time, the requirement still stands in our Sales contracts that all containers shall display a lead warning notice.

We already know that the levels are the same when we add lead to the blood, but the results may be different if we compare, thfiaethods when lead intoxicated blood of an animal is used.
