One thing has become quibo clear, in these studies, namely, that even slight changes in lead absorption are accompanied 2 Dr* B* C# Fisohbein by corresponding changea in tho transportation and excretion of lead, therefore we can use lead trans portation and excretion as an adequate measure of the magnitude of exposure* if observations are made in close tine relations hi p to tho exposure# Now in the case of tetraethyl lead in gasoline vse find that exposure to high concentrations of lead in the gasoline either by way of akin contact or by inhalation results in lead absorption# However when the dilution is sufficiently 1cm (1 part of tetra ethyl lead to 1000 parts of gasoline) there is no evidence that absorption occurs von after intensive and prolonged exposure.

Despite these regulations, it is a matter of observation that leaded gasoline has been used fog a variety of purposes and there has yet to be seen a case Of lead poisoning or of demonstrable lead absorption as a consequence of these mls-uses of the gasoline.
