870 LEAD POISONING--MCDONALD AND KAPLAN !

This campaign is designed to promote the sale of high grade jaint, which, of course, means white lead.

I have already told you my point of view about the use of de-leading procedures for diagnostic purposes* In my opinion the best measure of the lead content of the body is to study the lead excretion under the most nearly normal physiological conditions Here available data are very reliable.

Obviously, if there ia no lead absorption* tho factor of susceptibility to lead decs not enter into tho question.

Moreover, the leaded gasolines such as Baseline which are not sold under the name of Ethyl Gasoline, contain smaller amounts of lead than do the premium fuels known as Ethyl Gasoline* K 0021745 z For these reasons I do not believe that you need have any anxiety about your health from the point of view of lead poisoning# It is highly improbable that you have absorbed appreciable amounts of lead# The symptoms which you describe are associated with a variety of conditions# and indeed they are not unusual during or following periods of hot# muggy weather# I would advise that you ignore these symptoms of fatigue# If# however, they continue or progress and especially if they are associated with a loss of weight# it would be the better part of wisdom for you to consult a physician not with the idea of recognizing lead poisoning but with the idea of determining just what your physical condition is in relation to any one of a number of chronic infectious processes# Replying somewhat more directly to vour questions as to what are the early symptoms of lead poisoning# it should be said that one would not expect the symptoms of lead poisoning from the handling of Ethyl Gasoline to be different in any way from lotid poisoning developed In other lead trades* However# since I repeat that there have been no cases of lead poisoning from the handling of Ethyl Gasoline# it becomes apparent at once that it is not possible to describe this condition in any other than in terms of lead poisoning In general# There is no one symptom or combination of symptoms which are characteristic of lead poisoning alone* Thus it requires a careful and painstaking examination and chemical tests to establish with eny certainty the existence of early lead poisoning# If the above discussion does not answer your questions satisfactorily and if you wish to obtain any further advise from me about your general health# I should be pleased to have you writ me# Meanwhile# I should suggest that you make It a practice to use gasoline which does not contain lead for your shop work since such gasolines have no advantage for your purpose# and since thereby you will 3pare yourself any anxiety as to lead absorption from this source# In order to obtain such gasoline in the present market# you should make it a point to avoid all colored gasoline* and purchase a water white gasoline.

It isthen argued that blood lead level decreases cannot be explained by lead in paint or lead in the diet and, being unable to think of other lead sources or another variable that might correlate with gasoline lead use and blood lead levels, it is concluded that the decrease in blood lead levels is caused by the decrease in gasoline lead use.

Our manuscript on lead, to give lead some useful publicity, is complete.

V* .Conwell quit sure that no on has established a definite relationship between focal lesions of t&e brain and cord and lead absorption* As to the lead exposure involved in the handling of leaded gasoline 1 think we will have to accept on the basis of very sound evidence, that it is very minute indeed.

On must not forget, in this connection, however, that there have been mors than ten years of experience in this country, without a single case of lead poisoning or demons treble lead absorption as a consequence of the handling and use of leaded gasoline, The history of exposure to leaded gasoline, therefore, cannot be regarded as a significant item in a diagnosis.

Amounts of organic lead recovered from the effluent were insignificant and sampling for organic lead in the flue gas was discontinued after the second run.

The 0.1 milligram of lead which.
