Stormwater Bioretention: Nitrogen, Phosphorous And Metal Removal By Plants, Malgorzata Rycewicz-Borecki
Stormwater Bioretention: Nitrogen, Phosphorous And Metal Removal By Plants, Malgorzata Rycewicz-Borecki
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Stormwater runoff is an environmental concern. It increases the volume and velocity of surface water flow and contains high pollutant concentrations. High flows erode stream channels. Nutrients in the runoff cause eutrophication. Some metals from stormwater runoff is regulated by the Federal National Pollution Discharge Elimination System (NPDES). Bioretention (BR) systems are often used in response to these regulations to retain and treat this stormwater runoff.
This study conducted greenhouse and field experiments, and evaluated differences in nutrient and metal removal among plant species that are typically found growing in BR systems but are not typically investigated in this detail. …
An Assessment Of Polychlorinated Biphenyl Contamination In Fish From The Inland And Great Lakes Of Michigan, Emily Sokol
An Assessment Of Polychlorinated Biphenyl Contamination In Fish From The Inland And Great Lakes Of Michigan, Emily Sokol
Dissertations, Master's Theses and Master's Reports
Fish within the Great Lakes region of North America are an invaluable resource with economic and cultural significance. While these fish are vital, they contain chemical pollutants that are hazardous to human health. One such man-made group of chemicals, polychlorinated biphenyl compounds (PCBs), continue to be a problem long after the ban on production (1979).
The objective of this research thesis was to assess PCB contamination in fish within the Great Lakes Region. This objective was completed by determining the sources of PCB contamination, defining the ecosystem characteristics that significantly affect fish contamination, predicting when it will be safe to …
