In 2007, Washington became the first state in the nation to target all forms of highly toxic brominated flame retardants known as PBDEs for elimination from the many common household products in which they are used. A 2004 study of 40 mothers from Oregon, Washington, British Columbia, and Montana found PBDEs in the breast milk of every woman tested.
Three recent studies by the Washington Department of Ecology showed that toxic chemicals banned decades ago continue to linger in the environment and concentrate in the food chain. In one of the studies, state government scientists found unacceptable levels of toxic substances in 93 samples of freshwater fish collected from 45 sites. The toxic substances included PCBs; dioxins, two chlorinated pesticides, DDE and dieldrin, and PBDEs. As a result of the study, the department will investigate the sources of PCBs in the Wenatchee River, where unhealthy levels of PCBs were found in mountain whitefish. Based on the 2007 information and a previous 2004 Ecology study, the Washington Department of Health is advising the public not to eat mountain whitefish from the Wenatchee River from Leavenworth downstream to where the river joins the Columbia, due to unhealthy levels of PCBs. Study results also indicated high levels of contaminants in fish tissue that scientists collected from Lake Washington and the Spokane River, where fish consumption advisories are already in effect[3].
On March 27, 2006 Governor Christine Gregoire signed into law the recently approved House Bill 2322. This bill would limit phosphorus content in dishwashing detergents statewide to 0.5% over the next six years. Though the ban would be effective statewide in 2010, it would take place in Whatcom County, Spokane County, and Clark County in 2008.[39] A recent discovery had linked high contents of phosphorus in water to a boom in algae population. An invasive amount of algae in bodies of water would eventually lead to a variety of excess ecological and
