.^ lead (2) Fresh Sludge Sample Boot, Pennsylvania 1.5^o lead (3) Pipe Line Sludge from V/aste Pile Kontello, Pennsylvania 0.3*# lead (4-) Fresh Sludge from Sediment Trap Montello, Pennsylvania lead ^ The amounts of organic lead in all of the samples were lesHT than 0.00235&* The amounts of lead in all of these samples were less than amounts found in many samples of sludge and scale, but until vie have more information on the behavior of small percentages of lead in mixture with iron rust, I would recommend that precautions similar to those in cleaning tanks be taken when the sludge traps are cleaned.

Our primary concerns will be the following: 1) can the animal model now being used in this department to study lead-induced brain dysfunction be used to study renal dysfunction; 2) can lead produce renal tubular dysfunction other, than the reported Fanconi like syndrome, for instance., altered sodium excretion, urinary concentrating ability, or response to an acid /" stress; 3) at what stage of intoxication are glomerular function and renal hemodynamics affected; 4) do any of the above parameters correlate with blood or kidney levels of lead; 5) does infant lead exposure result in incom plete renal maturation or dysfunction that leads to adult renal failure.

' Concerning Leaded Gasolines December 8, 1933 Gentlemen: , There has been some controversy in our organization relative to the use of leaded gasolines.

February 5, i^HI The Lead Industries Association has announced a grant of (2500 to the School of Ceramics, Rutgers, The State University, for research on lead In eeramlce.

Thus, the aaount of lead in Lucitc4Atrylle Lacquer ranges fron nene to 24* with aost colors containing no lead.

First__ the patented electrolytic cells used in the process refine the metallic lead as they convert it into white lead ... thus excluding the impurities found in ordinary white leads.
