Lead exposure is a risk to any human, but children are most vulnerable to the element's neurotoxicity, which can lead to developmental delays, learning difficulties and mood changes among other symptoms.
Thomas Jefferson UniversityOct 28 2024 Lead exposure is a risk to any human, but children are most vulnerable to the element's neurotoxicity, which can lead to developmental delays, learning difficulties and mood changes among other symptoms. There has been some progress in reducing exposure and preventing neurotoxicity, but hundreds of thousands of American children are still affected.
Dr. Schneider had previously shown that rats living in an enriched environment – larger cages with toys and climbing structures – experienced fewer negative effects on cognitive function and brain chemistry caused by lead exposure. In the new work, infant rats exposed to lead received either low- or high-quality maternal care, as measured by the amount of licking, grooming and nursing the pups received. After weaning, the rats lived in either standard laboratory cages or enriched environments.
