Whether you believe the Hollywood rumor that Jeremy Piven dropped out of the Broadway production of Speed-the-Plow due to a heavy regime of partying and a subsequent rehab session, or his doctor’s assertion that the star was ill due to mercury poisoning from a high dose of sushi (two servings per day, Pivs? Good Lord), the winner in this agent’s nightmare is awareness of mercury contamination.

Piven went on Good Morning America on Thursday to explain himself, warn about excessive consumption of fish high on the food chain like tuna, and point people to BlueVoice.org. BlueVoice correctly pins the blame largely on coal-burning power plants and their propensity to sprinkle lakes, rivers, and oceans with emissions high in methylmercury that bioaccumulates up the food chain. I’d call that, um, a quicksilver lining.
