“Toxic Hannah” Pingree will be on CBS Evening News with Katie Couric tonight at 6:30.

Pingree, Maine’s House Majority Leader, participated in a Natural Resources Council of Maine study last year where her body was tested for chemicals, an effort to bring awareness to the hazards found in everyday items.

For the past four years Pingree has led efforts to ban penta, octa and deca, flame retardant chemicals found in television sets and furniture.

CBS news reporters visited Pingree at her home on North Haven island. The piece will be about Pingree and the 12 other Mainers tested for chemicals, and the battle to remove chemicals from everyday products.

The segment will air after the local CBS affiliate hosts a live debate that Pingree’s mom, a candidate in the First Congressional District, will be participating in.

The debate begins at five on WGME and will feature CD1 candidates: Michael Brennan, Mark Lawrence, Chellie Pingree, Steve Meister, Ethan Strimling and Adam Cote.
