TLDR
Values were within the ranges normally observed in the river, suggesting that the dredging operations did not induce a significant PCB pulse of potential hazard to the estuary, and the input of PCB into Puget Sound via the Duwamish River was estimated to be 36 kg/year.About:

TL;DR: 2,3,7,8-tetrachlorodibenzo-p-dioxin is able to disrupt epidermal homeostasis and identify EGFR signaling as a regulator of the AHR, a transcription factor that binds to the Ah receptor nuclear translocator to regulate the transcription of numerous genes.

Trophic importance of Spartina alterniflora production and decomposition to the marsh-estuarine ecosystem
TL;DR: A re-evaluation of current data on production and decomposition of Spartina alterniflora in North American salt marshes, with regard to the role of these processes in the estuary, has resulted in the following generalisations as discussed by the authors.

Estuarine dredge and fill activities: A review of impacts
TL;DR: In this paper, the effects of dredging and fill activities in estuaries have many environmental effects, most of which are deleterious, including reduced light penetration by increased turbidity; altered tidal exchange, mixing, and circulation; reduced nutrient outflow from marshes and swamps; increased saltwater intrusion; and creation of an environment highly susceptible to recurrent low dissolved oxygen levels.

PCB availability assessment of river dredging using caged clams and fish
Clifford P. Rice,David S. White +1 more
TL;DR: The effects of dredging to remove sediments contaminated with polychlorinated biphenyls (PCBs) were studied in the South Branch of the Shiawassee River in south-central Michigan as mentioned in this paper.

Environmental contaminants in great blue herons (Ardea herodias) from the Lower Columbia and Willamette Rivers, Oregon and Washington, USA
TL;DR: The results support the use of great blue herons as a biomonitor for contamination in aquatic ecosystems because their relatively low sensitivity to organochlorine contaminants and high trophic position allows contaminant accumulation and biomagnification without immediate adverse effects that are often seen in other, more sensitive species.

TL;DR: In this paper, the authors used electron capture gas chromatography (EC/GC) for quantification of the ion pattern of polychlorinated biphenyls (CI2CInHIO_n with n = I, 2... I0).
