Relation of blood lead levels and lead in gasoline: an updated systematic review.

ABSTRACT:

Background

Millions of tons of lead were added to gasoline worldwide beginning in 1922, and leaded gasoline has been a major source of population lead exposure. In 1960s, lead began to be removed from automotive gasoline. Removal was completed in 2021.

Objectives

To determine whether removal of lead from automotive gasoline is associated with declines in population mean blood lead levels (BPb).

Methods

We examined published studies that reported population blood leaded levels for two or more years, and we calculated average concentrations of lead in gasoline corresponding to the years and locations of the blood lead level measurements.

Results

Removal of lead from gasoline is associated with declines in BPb in all countries examined. In some countries, BPb cont
