Washington, March 29 : Cumulative exposure to lead at levels likely to be experienced in community settings may have adverse consequences for women’s cognition in their later years, according to a study.
The study, supported by the National Institute of Environmental Health Sciences, was conducted with a view to examine biomarkers of lead exposure in relation to performance on cognitive tests given to older women.
Lead exposure is measured in two ways—blood lead level, which is a reading of recent lead dosage; and bone lead level, which is a cumulative measure of lead exposure over many years.
