The Homer City Generating Station rises like a cathedral out of a valley in Indiana County, just east of Pittsburgh. You can see its smokestacks and hour-glass shaped cooling towers from miles around. 

Like many coal plants around the country, workers at Homer City are busy installing pollution controls to comply with new clean air rules imposed by the EPA.

These units take out sulfur and other harmful pollutants, like mercury. Total cost? $750 million.

A new study suggests that there may be a link to exposure to air pollution and developmental disorders like autism.

Dr. Dr. Deborah Cory-Slechta is Professor of Environmental Medicine at the U of R Medical Center and lead author of the study.

She says when newborn mice were exposed to air pollution -- especially ultrafine particle pollution -- there was an enlargement in the parts of the brain that is seen in humans who have autism and schizophrenia.
