title: Tributyltin contamination and imposex in Alaska harbors.
abstract: We quantified imposex in file dogwinkles (Nucella lima) and tributyltin (TBT) contamination in bay mussels (Mytilus trossulus) from 10 harbors and nearby control sites throughout Alaska. We found evidence of TBT contamination in mussels from four harbors (29-54 ng TBT/g wet tissue wt). Two of these harbors now show reduced TBT contamination relative to levels found in 1987. We were able to find and collect dogwinkles from seven sites. Of these, all three dogwinkle samples from harbor sites exhibited imposex, with 36%-87.5% females affected per site. In total, six of the 10 harbors had some evidence of TBT contamination.
