Description This study measured polychlorinated dibenzodioxins and dibenzofuran (PCDD/F) concentrations in surface sediments collected from 21 stations throughout inner Bellingham Bay. Assuming nondetect congeners were one-half the estimated detection limit, the total PCDD/F toxic equivalent (TEQ) in the samples ranged from 0.54 - 19.8 ng/Kg and averaged 6.54 ng/Kg. The average total TEQ in an area receiving sediment from the Nooksack River was 1.62 ng/Kg. This value was not significantly different from the average for surface sediments in clean areas throughout Puget Sound. Study results may facilitate cleanup decisions and can help demonstrate bay-wide changes in PCDD/F concentrations.
