For example, people who work with mercury, leaded paints, tetraethyl lead, and other potentially dangerous substances are exam ined as regularly as necessary to make sure they are not absorbing dangerous amounts into their bodies.

The oth er sid e of the problem is that which d e r iv es from the ex p erim en ta l work which we have done in relation to the toxic hazards of tetraethyl lead and gasolin e containing it.

This depends primarily on the quantity and character of the halogen carrier mixed with tetraethyl lead to make the antiknock compound.

Likewise, samples of soil obtained where lead is used in cities (de Trevilie, 1964), in rural areas near mines and lead industries .

The primary factor which might give rise to hazard through the substitution of this compound for. tetraethyl lead in equivalent concentration in gasoline (equivalent in terms of the proportional representation of lead in the molecule, whereby, at the maximum,. 2.03 ml. of TEL are equivalent to 3.00 ml. of TEL), was that of the appreciably greater volatility of tetramethyl lead./ The practical question revolved around the extent to which this higher volatility might operate with significant affect to contaminate the air with '" >' . :

Th total effect is to differentiate garage m echanics, as a class, from the handlers and Users of leaded gasoline, by reason of a barely significant in crease in the m ean level of th e ir U rinary lead excretion, and by a somewhat le ss pronounced in c re a se in the lead concntrtion in th e ir blood (the u rin a ry v alu e is about 0, 05 m

Kiebylski This paper presents the results of a comprehensive study of the amount, composition, and particle sise distribution of _3_ K: 00v 73y G the lead compounds present in the exhaust gases of automobile engines operated on fuels containing tetraethyl lead* It was found that city-type driving tends to exhaust considerably less lead than is burned by the car and that the excess lead which deposits on exhaust system surfaces tend to bo exhausted under higher speed or higher load conditions.

Two other factor* vfclch will restrict th* continued growth of tb* laad anti knock business during th* next five years are th* Increasing use of load alibis other than tetraethyl lead, and a reduction in exports.
