Why's That on the Red List?

Several groups publish “red lists” of chemicals and materials of concern in building products. Most of the substances on these lists are there for obvious reasons: they are common and may contribute to global warming, increase cancer risk, or bioaccumulate in ecosystems. Other red-listed chemicals and materials, however, cause a certain amount of head-scratching among some of us because we didn’t think of them as very toxic.
