Description: NOAA’s Mussel Watch Program monitors the status and trends of chemical contaminants of U.S. coastal waters, measured in filter-feeding bivalves (oysters or mussels). This national assessment (Kimbrough et al. 2008) reports results for eight metals (Arsenic, Cadmium, Copper, Mercury, Nickel, Lead, Tin, and Zinc) and six classes of organic contaminants (Butyltins, Chlordanes, DDTs, Dieldrins, PAHs, and PCBs). Results are generally reported in parts per million (ppm) dry weight for metals, and parts per billion (ppb) dry weight for organic contaminants. This study features five sample sites in Alaska, one of which (site CIHS, Cook Inlet – Homer Spit) is in Kachemak Bay, with mussel (Mytilis sp.) as the sampled species. Sampling was done in 2005, and compared with previous years to discern trends for each contaminant (increasing, decreasing, or no trend). An aggregate index is calculated for both metals and organic contaminants, reported as Metals_status, Metals_trend, Organic_status, and Organic_trend. Levels for most contaminants at site CIHS are ranked as “low”, with no discernable trends. Arsenic (As) occurs naturally in some glacial-origin sediments of Alaska and is the only contaminant ranked as “medium” in this study. This summary report (Kimbrough et al. 2008) is available for download as a pdf at ftp://ftp.library.noaa.gov/noaa_documents.lib/NOS/NCCOS/TM_NOS_NCCOS/nos_nccos_74.pdf
