Such sensible action ought to be duplicated elsewhere. Old fever thermometers, like batteries and fluorescent lights, are a significant source of residential mercury pollution. Maine already has placed restrictions on freshwater fish consumption because of the toxin's presence. Mercury poisoning can lead to development problems, especially when it affects unborn and young children. Town Councilor David Soley, who authored Freeport's ban, says outdoor thermometers use alcohol rather than mercury and are unaffected by the law.
Digital thermometers are also more accurate and easier to use.
Maine has worked hard to clean up industrial mercury pollution in recent years. Legislators would be wise to take the Freeport ban and apply it to the entire state.
