Rational Lead ha a new lead chromate pigment -under development that is called 1-50 Basic Lead Sllicp-Ohpomat.. .Essentially, this is a lead chromate shell on a core of silica and it is claimed that this offers the advantages of straight lead chromate at a lower cost.

Five years later, when all blood lead levels were 30 ug/dl or less, lead effects on IQ were no longer significant.

Nineteen states either require or permit lead-zinc paints and five more allow red lead or blue lead paints containing high proportions of the lead pig ments.
