Low lead levels in children negatively affect test scores

As reported in the October 4, 2016 issue of Science Daily, a Brown University study reports that lead exposure among preschoolers can predict low reading scores in subsequent years. The study suggests that “because poor and minority children are more likely to be exposed to lead, lead poisoning may be one of the causes of continuing gaps in test scores between children from different socioeconomic groups.” The data for the study came from the Rhode Island lead abatement and testing program through which repeated blood lead level tests were conducted.
