'Jith reference to our experience, I should point out to you that the lead exposure associated with the cleaning of gasoline storage tanks, if such occurs, is a matter of absorption of tetraethyl lead or its organic decomposition products.

In 1953 Cholak wrote an article in the Archives of Industrial Hygiene and Occupational Medicine, suggesting an improvement in the method to identify the organic compounds of lead which might exist in the urine in the tetraethyl lead industry, alongside with the ionic lead which is alone picked up by the ordinary short method of analysis.

I volunteered-to do thi3 analytical work because X was intereste& in seeing that you got off to a good start, but also because I was very much interested in connection with our experimental studies, in obtaihing data on the lead Intake and output of French Workmen, Having obtained these samples before the actual work in the tetraethyl lead plant had begun, we were enabled to learn something of these facts without the of the factor of occupational lead exposure.
