"It's a sunny morning in the Poconos. As residents prepare to head to work or school, some begin to feel dizzy or light-headed."

"Others have difficulty breathing or complain of itchy eyes.

Few, if any, realize that sulfur dioxide, a colorless, odorless gas used as a bleaching agent and industrial solvent, has been accidentally released into their neighborhood.

If nothing's done, their lungs will fill with fluid and, eventually, some will stop breathing altogether."
