This treatment returns the exhaust system to a condition where it again accumulates lead deposits and exhausts less lead in subsequent driving at moderate speeds.

I mention it, however, "isolated measurements of air lead values have some value"-- might well be altered to say that such measurements "of lead in air have some value" etc.

The Lead-In-Air Analyzers and the reagents will be furnished by the lead suppliers.
