Sediment health in the central sound from just south of Whidbey Island to the Tacoma Narrows has deteriorated over the past decade, according to the report, which has some scientists who closely monitor the watershed wondering what they been missing. The study of sediment pulled from the bottom of the sound in 2008 and 2009 found a decline in sedimentdwelling life known as benthic invertebrates in 28 percent of the region, compared with 7 percent of the region in results from 1998 and 1999. The results were surprising in contrast with other recent health checkups for Puget Sound, which have shown improvements such as a decrease in toxic chemicals. Scientists also have found a decrease in concentrations of lead, mercury, silver, tin and other toxics in the central sound sediment. It is possible scientists have not been looking deep enough or broad enough for other environmental problems, said Rob Duff, manager of the Ecology Department environmental assessment program. don measure everything. We measure dozens and dozens of chemicals we are concerned about, Duff said, adding, are thousands and thousands of chemicals in commerce today. contaminants such as pharmaceuticals and personal care products may be responsible for the decline in the number and variety of small creatures within Puget Sound sediment, Duff said, but there are other possible causes. The decline in the number and variety of small creatures in the sediment also result from natural influences, such as the normal population cycles of sedimentdwelling organisms, or sediment movement and changes in dissolved oxygen, pH and ammonia levels in the water above the sediments. report only tells you a piece of the puzzle, cautioned Jan Newton, an oceanographer from the University of Washington who was not involved in this Ecology Department study. The health of Puget Sound is so multifaceted from toxics to habitat to climate change it difficult to talk about its overall health, she said. She added, there reason for concern. the health of Elliott Bay in Seattle and Commencement Bay in Tacoma has been showing signs of improving health, with decreases in chemicals found and better water chemistry overall. That suggests years of port cleanup and stormwater management seem to be working, said Maggie Dutch, lead scientist for the sedimentmonitoring program. But the contrasting results also suggest the need for more research, she added. thinking that there are other things happening, Dutch said. could be things that we also have an influence on. kind of report shows the importance of continuing to monitor the sound as a tool for figuring out what else needs to be done to clean up the water, said Ken Dzinbal, who represents the Puget Sound Partnership on the monitoring program.Pin #by #Marlene #Estrada #on #Love #this #style
