“…Lake Erie transitioned from an oligotrophic state prior to 1880 to a eutrophic lake state after 1950. The lake's biological productivity has ever since remained fairly high, despite the fact that rigorous nutrient abatement programs began as early as in 1969 and that a target reduction of tributary loading was reached in 1983 49 50 51 . Our results also showed that the anthropogenically-induced eutrophication history of Lake Erie was compounded by regional climate change.…”

Many freshwater and coastal marine ecosystems across the world may have undergone an ecosystem regime change due to a combination of rising anthropogenic disturbances and regional climate change. Such a change in aquatic ecosystems is commonly seen as shifts in algal species. But considerably less detail is known about the eutrophication history in terms of changes in algal productivity, particularly for a large lake with a great deal of spatial variability. Here we present an analysis of trace metals (Cu, Ni, Cd, and Pb) on a sediment core recovered from Lake Erie, off the Vermilion coast of northern Ohio, USA, to reconstruct the eutrophication history of the lake over the past 210 years. Following a slow eutrophication during European settlement, Lake Erie experienced a period of accelerated eutrophication, leading to an ecosystem regime transition into a eutrophic lake state in 1950. Our results suggested that the lake's biological productivity has ever since maintained fairly high even though a significant input reduction was realized from rigorous nutrient abatements that began as early as in 1969. This work underscored the role of in-lake biogeochemical cycling in nutrient dynamics of this already eutrophic lake.

A Comparison of Rural and Urban Fluvial Systems as a Function of Land Cover Changes in Summit County, Ohio

Population growth during the 20th century in Northeast Ohio has led to an overall increase in developed land cover and anthropogenic pollution such as fossil fuel combustion. Urban expansion and fossil fuel combustion result in an increase of polluted runoff into fluvial systems, which jeopardizes water quality, undermines infrastructure, and stresses local ecosystems that buffer floods. This study compares heavy metal pollution levels and land cover change during the 20th century in dammed impoundments within the rural Haskell Run watershed (Lake Butler), the rural Ritchie Run (Lake Litchfield), and the urban Mud Brook watershed (Old Mill Pond) in Northeast Ohio. Surficial sediment samples were collected from each impoundment to assess current pollution levels and sediment cores were collected for the past record of pollution. The two end-member watershed types have similar bedrock, glacial history, and climate, however, land cover differs greatly. Between 1985-2010, there was no land cover change in the rural Ritchie Run watershed, and in 2010, Ritchie Run had 3.4% developed land cover and 0.63% impervious cover. During the same period, the rural Haskell Run watershed increased by 1.37% in developed land cover, and in 2010, 12% of the Haskell Run watershed was developed land and 3.3% was impervious cover. Developed land cover, from 1985-2010, increased by 15.3% in the urban Mud Brook watershed, and in 2010, 74% was developed land cover and 23% was impervious cover. Old Mill Pond impoundment sediments were found to have higher heavy metal and ferrimagnetic concentrations, whereas, Lakes Butler and Litchfield sediments have comparatively lower heavy metal and ferrimagnetic concentrations. There is a moderate direct relationship iv between heavy metal and ferrimagnetic content. Therefore, magnetics can be used as an inexpensive and rapid screening tool for heavy metal pollution studies. The Old Mill Pond sediment core records an increase in heavy metal and ferrimagnetic concentration in the early 20th century, peaking in the 1940s-1960s when Cuyahoga Falls experienced a doubling in population. Since the 1970s-1980s, after the Clean Air Act (1970) and Clean Water Act (1972) were enacted, the heavy metal and ferrimagnetic concentrations decreased to present-day. The study supports that more developed land cover and impervious surfaces in a watershed lead to higher levels of anthropogenic related pollutants in fluvial systems. Sediment cores and aerial photographs from Lakes Butler and Litchfield indicate a history of both delta progradation and flood events. Studies, such as this, can assist in informing local policy makers and land managers when considering the effects of urban expansion, preservation of ecosystems and undeveloped spaces, and the effectiveness of national and local environmental regulations. v ACKNOWLEDGEMENTS Obtaining a master's degree is a long and arduous process, and aside from my own efforts, there were many people who helped me to reach this important goal.

“…The input of P into water bodies mainly comes from non‐point source pollution, which is caused by pesticides and fertilizers in agricultural activities, livestock waste, domestic sewage, storm‐water discharge, and urban runoff . As numerous studies have shown, a high loading of P leads to a high risk of water‐quality degradation, a shortage of dissolved oxygen in the water body, a decrease in biodiversity, and an increase in algal outbreak . Soil infiltration systems between agricultural fields and aquatic ecosystems have been widely recognized as the last barrier to prevent P from flowing into the reservoirs, rivers, lakes, and seas by plant retention and soil adsorption .…”

A comparative study was conducted to investigate the adsorption characteristics of phosphorus (P) on two soil samples collected from a typical subtropical reservoir and to reveal the possible influence of alternating exposure and inundation on the P adsorption onto soil in a water level fluctuation zone. Short-term batch experiments were performed, and characterization methods, such as scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy, were also used. The P adsorption kinetics for both soils was best described by a pseudo-second order model (R 2 > 0.99). A modified Langmuir model described the P adsorption on both samples well, and low temperature increased the risk of releasing soil P into the overlying water. Low pH values were not conducive to the P adsorption process. It appeared that alternating exposure and inundation had no significant impact on the adsorption capacity of P onto soil from water level fluctuation zones in this research. pH, SEM, and FT-IR analyses demonstrated that Fe, Al, and Ca contained in the clay minerals of the soil played an important role in the adsorption of P onto soil from water level fluctuation zone.Abbreviations: BET, Brunauer-Emmett-Teller; EPC 0 , zero equilibrium phosphorus concentration value; FT-IR, Fourier transform infrared; NAP, native-adsorbed exchangeable phosphorus; SEM, scanning electron microscopy; XRF, X-ray fluorescence. 975
