North Carolina's coal ash pits figure among those that exceed federal pollution limits, according to a report issued today by by environmental advocates.

The report from the Environmental Integrity Project says that 33 coal ash disposal sites in 19 states are exceeding federal limits on arsenic, lead and other contaminants.

Three of the sites listed are in North Carolina at coal-burning power plants in Wilmington, Goldsboro and Belews Creek that are operated by Duke Energy and Progress Energy.

A study at the University of California at Irvine has determined that safe and eco-friendly LED bulbs, commonly used in headlights, stoplights and holiday lights, contain lead, arsenic and other hazardous subtances.
