Evaluation Of An Educational Campaign To Improve The Conscious Consumption Of Recreationally Caught Fish, Corey A. Krabbenhoft, Susan Manente, Donna R. Kashian
Evaluation Of An Educational Campaign To Improve The Conscious Consumption Of Recreationally Caught Fish, Corey A. Krabbenhoft, Susan Manente, Donna R. Kashian
Environmental Science and Geology Faculty Research Publications
Consumption guidelines are a common way of improving conscious consumption behaviors in areas where game fish are known to contain contaminants. However, guideline information can be difficult to distribute, and effectiveness difficult to measure. To increase the distribution and effectiveness of guideline information for the Detroit River, an educational campaign was launched in 2010, which included distribution of pamphlets with consumption information, posting of permanent signs at popular fishing locations, and hiring River Walkers to personally communicate with anglers. In 2013 and 2015, we conducted in-person surveys of active shoreline anglers to determine the effectiveness of education and outreach efforts. …
Estimating Watershed Mercury Contribution To Lake Fort Smith State Park, Arkansas, Usa, William Miles Harmon
Estimating Watershed Mercury Contribution To Lake Fort Smith State Park, Arkansas, Usa, William Miles Harmon
Graduate Theses and Dissertations
Mercury contamination associated with human activities poses global human health and environmental risks. A fish-consumption advisory has been in effect at Lake Fort Smith in central west Arkansas for more than a decade due to observed methylmercury concentrations in fish tissue. Lake Fort Smith is an important municipal drinking water supply and recreational resource. Water samples from the majority contributing tributary stream, Frog Bayou creek, were collected periodically, under differing hydrologic conditions in order to quantify the allochthonous mercury load delivered to the lake. Temperature, specific conductance, and turbidity data were collected and used to estimate dissolved organic carbon, methylmercury …
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 …
A Model To Predict Concentrations And Uncertainty For Mercury Species In Lakes, Ashley Hendricks
A Model To Predict Concentrations And Uncertainty For Mercury Species In Lakes, Ashley Hendricks
Dissertations, Master's Theses and Master's Reports
To increase understanding of mercury cycling, a seasonal mass balance model was developed to predict mercury concentrations in lakes and fish. Results indicate that seasonality in mercury cycling is significant and is important for a northern latitude lake. Models, when validated, have the potential to be used as an alternative to measurements; models are relatively inexpensive and are not as time intensive. Previously published mercury models have neglected to perform a thorough validation. Model validation allows for regulators to be able to make more informed, confident decisions when using models in water quality management. It is critical to quantify uncertainty; …

Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey
Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey
Technical Reports
Mercury (Hg) contamination of fish is a widespread problem throughout much of the United States and the world (Louisiana WWW page, 1997). Levels ofHg in fish suffic1ent to exceed the FDA action level of 1 mg kg-1 have been found in many water bodies, including some in Arkansas and Louisiana. As a result of the serious public health ramifications for developing fetuses and for people that subsist on native fish, fish consumption advisories due to Hg contamination have been issued in 29 states. Contamination of surface water bodies by Hg results from deforestation, forest fires, fossil fuels, mining, natural emissions …
