F o r practical purposes, and for use in cleaning generally ,the lead concentration in clear gasoline which has never been treated with tetraethyl lead, is an item of no importance.

Under certain conditions it appears,that these triethyl lead compounds wvithin the sludge, (not that in the adherent scale), may be reconverte^into tetraethyl lead.

Tetraethyl Lead. " The other article is much more extensive, but specific attention should be called to the extreme skin exposure of the m e n enga g e d in f i l l i n g b a r rels.

A large number of conditions, such as the above, would have to be net, particularly the ones specifying complete absence cf ventilation and full day's exposure under identical conditions, and probably more importantly, a rate of volatilization of organic lead from the sludge sufficiently rapid to effect saturation in the tine allotted, fhis would occur probably only if the organic compounds were pure tetraethyl lead and they did not undergo any decomposition in the period of standing, in line with this, it would be advantageous to know the rate of evaporation of organic lead from sludge and the influence of ventilation on this.

The mixing of anti-knock compounds is an integral part of manufacturing operations for tetraethyl lead# and un doubtedly# this will be the case throughout the entire period of the war.

Ihis would occur probably only if the organic compounds were pure tetraethyl lead and they did net undergo any decomposition in the period of standing.

The exposure of persons to leaded gasoline is no^/occupational hazard, and under the conditions of its handling,the absorption of tetraethyl lead through the skin cannot occur to an appreciable degree.
