Assessment Of Metals In Tissues Of Marine-Associated Birds In South Florida, Caitlyn A. Nay
Assessment Of Metals In Tissues Of Marine-Associated Birds In South Florida, Caitlyn A. Nay
HCNSO Student Theses and Dissertations
Seabirds – broadly defined as any bird species associated with the marine environment – are exposed to a wide range of environmental contaminants. Vectors of exposure to metal pollution include by external contact, inhalation, and most often ingestion of food and incidental seawater. Seabirds are often considered marine ecosystem bioindicators due to their high trophic position, relatively long lifespan, and wide geographic ranges. We examined the concentration of total mercury (THg), lead (Pb), and cadmium (Cd), in the kidney, liver, breast muscle, and feathers of seven species of juvenile and adult seabirds commonly found in South Florida: brown pelican Pelecanus …
Mercury Trends In Cormorant And Great Blue Heron Eggs From Pacific Canada: A Question Of Local And Global Sources, Tanya Brown, John E. (John Edward) Elliott, Kyle Elliott, Sandi Lee
Mercury Trends In Cormorant And Great Blue Heron Eggs From Pacific Canada: A Question Of Local And Global Sources, Tanya Brown, John E. (John Edward) Elliott, Kyle Elliott, Sandi Lee
Salish Sea Ecosystem Conference
Mercury (Hg) levels and trends in the NE Pacific Ocean are due to the convergence between natural and anthropogenic sources, with the latter broadly related to a combination of local and long-range sources. Legacy and current local point sources include chlor-alkali plants, pulp and paper mills and other mixed sources. In addition, long-range atmospheric and oceanic pathways deliver mercury to the Pacific coast, primarily from points to the west, where it is taken up by algae and bacteria and transferred through the marine food web in its inorganic form, but also its organic form, methylmercury. We present data on Hg …
Spatial Comparison Of Pbts In Marine Fish And Invertebrates From King County Waters, Rory O'Rourke, Jenée Colton, Debra Williston
Spatial Comparison Of Pbts In Marine Fish And Invertebrates From King County Waters, Rory O'Rourke, Jenée Colton, Debra Williston
Salish Sea Ecosystem Conference
In 2014, King County initiated a long-term monitoring program of marine tissue contaminants. The program monitors important prey of marine mammals and species collected for human consumption: Dungeness and Red rock crab, English sole, market squid, and rockfish (brown, copper, and quillback). Sampling locations include Elliott Bay and central Puget Sound sites within King County waters. Generally, PCB concentrations in all species were higher in Elliott Bay compared to other King County locations. With a few exceptions, PBDE concentrations in all species generally exhibited less of a distinct geographical pattern than was observed for PCBs. Contaminant data for Puget Sound …
Persistent Bioaccumulatives In Freshwater Fish Of The Lake Washington Watershed, Jenee Colton, Rory O'Rourke, Richard Jack
Persistent Bioaccumulatives In Freshwater Fish Of The Lake Washington Watershed, Jenee Colton, Rory O'Rourke, Richard Jack
Salish Sea Ecosystem Conference
In 2013, King County initiated a long-term monitoring program of freshwater tissue contaminants in three major lakes (Lakes Sammamish, Washington, and Union) and two major rivers (Green and Cedar rivers). Tissue samples are collected from each waterbody every 5 years. Fillet and whole-body fish and invertebrate tissue chemistry data from this program are used to track changes over time associated with management actions, evaluate the risk of adverse effects to aquatic life, and inform human health risk evaluations of fish consumption. The first round of tissue monitoring from all three major lakes was completed in 2017. Species collected spanned a …
