Bleecker et al. conclude that lead smelter workers with lower cognitive reserves (CR) were more susceptible to the effects of lead on cognitive performance tests than workers with higher CR.1 The authors do not mention why some workers had a lower CR.
One hypothesis is that some workers—as children—may have been exposed disproportionately to high levels of lead. Antenatal and postnatal exposure to environmental lead has been shown to result in cognitive deficits that persist into later childhood and adulthood.2,3
