Researchers have found that bricks made from fly ash–fine ash particles
captured as waste by coal-fired power plants–may be even safer than
predicted. Instead of leaching minute amounts of mercury as some
researchers had predicted, the bricks apparently do the reverse,
pulling minute amounts of the toxic metal out of ambient air.
