More cautionary science on deca below, one of three PBDE flame retardants still on the market.
A bill to phase out deca in Michigan is stalled in the legislature.
In the meantime, deca levels are rising in wildlife and sediments in the state.
Lots of good companies have already phased it out, and alternatives are available for all uses to be phased out.
Michigan shouldn't wait any longer to prevent another major toxic legacy in the Great Lakes.
"Early studies suggested deca didn't get into the environment or animals and that it did not alter its composition to resemble the more toxic varieties that are off the market, Hale said. But he said more recent studies, including the work on New England's peregrines, suggest scientists "missed the ball" originally by suggesting the deca variety did not accumulate in the environment."
Biologists studying peregrine falcons in New England are elated that their numbers are rising, but concerned about a new threat they fear will reverse years of progress in rebuilding the bird population, and possibly harm people.
A study of falcon eggs that failed to hatch shows high levels of flame-retardant chemicals called PBDEs. Two samples found in unhatched eggs from a nest on Frankenstein Cliff in New Hampshire's Crawford Notch State Park contained the highest overall concentration of the chemicals.
"I'd like to think we are getting the alarm out about this concern at a time when action can be taken, as opposed to waiting until the birds start disappearing," said Chris Martin, a New Hampshire Audubon raptor specialist.
