Recent research indicates that living in areas of high pollution has serious long term implications. Living in these areas during childhood and adolescence can lead to diminished mental capacity and increased risk for brain damage. People of all ages who live in high pollution areas for extended periods place themselves at increased risk for various neurological disorders. Both air pollution and heavy metal pollution have been implicated as having negative effects on central nervous system functionality. Pollution's ability to affect individuals' neurophysiology after central nervous system structure is fairly stabilized is an example of negative neuroplasticity.
