Foreword The hygienic control of operations involving the production or use of lead tetraethyl differs from that required, in the more common lead trades, in that there is serious danger of exposure to a liquid organic lead compound, as well as to inorganic lead compounds* Exposure to lead tetraethyl arises from the. volatility of this compound and also from its absorbability through the healthy unbroken skin.

Therefore, there is a lag in the' determination-of the relationship between lead in the skeleton and lead in the circulating medium and in the urine.

of those exposed to lead tetraethyl.

As a result, the lead industry must seek new markets for the lead formerly used in antiknock additives.

Moreover, the lead concentration in the blood in both instances is such that symptomatology from lead absorption could have existed.

It has been demonstrated experimen tally that lead compounds are absorbed rapidly and completely from the nasal pas sages when they have no chance to go either into the digestive system or deeper mto pling to ensure control of contamination and physical examinations to keep track of lead absorption by employees, can eliminate lead poisoning from battery plants The poisoning produced by inhalation of solid inorganic lead compounds commonly causes symptoms of lead colic and lead anemia.

From indirect observations I became convinced that the lead intake of the normal human body could be increased several times without danger of lead poisoning, I * therefore* began feeding experimental subjects definite quantities of lead while following carefully their total lead intake and their total lead output.

Moreover, if an abnormal type or degree of absorption of lead continues regularly over any considerable period of time, lead tends to accumulate, to some extent, in the body, and with this there is a corresponding increase in the lead content of the blood, as well as that of the urine.
