The data shows that Black students are disproportionately exposed to lead in racially segregated neighborhoods and that these stressors are linked to poor test scores in reading among Black youth relative to their white peers.
“This study suggests that the long history of structural racism — which among many other things has produced racially segregated neighborhoods — and environmental injustice can combine to systematically disadvantage specific students and groups of students in the US,” Bravo said.“Maybe you can do something to help them so that they aren’t actually at risk of dropping out of high school or of not going to college or dropping out of college,” she said.
