Concentrated ambient fine particulate matter (PM) exposure induce brain damage in pre and postnatal exposed mice.

Air pollution is a public health concern that has been associated with adverse effects on the development and functions of the central nervous system (CNS). However, studies on the effects of exposure to pollutants on the CNS across the entire developmental period still remain scarce. In this study, we investigated the impacts of prenatal and/or postnatal exposure to fine particulate matter (PM) from São Paulo city, on the brain structure and behavior of juvenile male mice.
