[see abstract above], using dentine lead content as a marker of previous lead exposure, have found that children with high dentine lead, none of whom had overt lead poisoning, performed significantly less well on IQ tests than their counterparts with low lead content.

The manufacture of storage batteries, the largest use of lead, consumed 245,200 toils of soft lead and 221,500 tons of lead in antimonial lead in comparison with 237.400 tons of soft lead and 234,600 tons of antimonial lead in 1966.

(The lead in question here was lead carbonate.)

Basic lead acetate solution to first prepared by dissolving lead oxide, formed on the surface of highly purified, feathered lead through the action of air, in normal lead acetate solution.

We have come to recognize that pollutant lead levels on a world-wide scale are tens to thousands of times larger than natural lead levels, and that the route: ore lead, to tetraethyl lead, to atmosphere, to seas is of major importance.

M-25 and N-25 Chromated Red Leads combine the best properties of red lead and the lead chromates.

Red lead and linseed oil also form lead soaps but more slowly because red lead is less reac tive with linseed oil than is litharge.
