E-M:/ Mercury Levels Decline Near Tightly Controlled Incinerators

Title: Mercury Levels Decline Near Tightly Controlled Inciner
Fascinating article in the Boston Globe showing that reducing mercury from local sources results in real declines in mercury in fish.  Presumably, getting rid of the incinerators entirely would be even better, not to mention controlling the other major sources. 

Mercury down 32% in fish near Mass. incinerators

Progress tied to emissions laws

By Beth Daley, Globe Staff  |  April 3, 2006

Seven years after Massachusetts enacted the nation's toughest mercury emission laws for incinerators, amounts of the toxic metal have declined by 32 percent in a signature freshwater fish caught near some of those facilities.

A significant amount of the state's inland fish remain unsafe for a large portion of the population, but state officials and environmental advocates say they are stunned by the dramatic turnaround in yellow perch from lakes near a cluster of incinerators in the northeast corner of the state.

State officials now estimate the improvement in yellow perch is about half of that needed to make the fish safe to eat. And good news for perch -- used as an indicator species because it accumulates high levels of mercury -- also means good news for other lake fish across Massachusetts.

However, state officials said much more needs to be done. They could not estimate when it will be OK to lift a strict warning for women of childbearing age and children about eating fish from the state's lakes and streams.
