Perhaps it would be appropriate for Al Gore’s Web site to display a disclaimer warning you about the dangers of compact fluorescent light bulbs (CFLs), but he doesn’t. According to the Washington Post’s Eco Wise columnist Eviana Hartman, “they contain a small amount of mercury, a potent neurotoxin.” “If you toss the bulbs in the trash, they're likely to break, potentially exposing workers to mercury or releasing it into groundwater and soil from landfills,” Hartman wrote in the October 7 Washington Post.
