Using Visual Prompts And A Raffle To Increase Recycling On Campus, Heather Marie Felske
MSU Graduate Theses
Landfills pose a risk to the current level of human development and population growth. Leachates have the potential of polluting the ground water which can cause severe birth defects and decrease the population. When municipal solid waste breaks down it produces methane gas creating debilitating health problems that are fatal. More attention will have to be directed towards sustainable growth by reducing the amount of recyclable materials being discarded as waste. Part of the public affairs mission of Missouri State University is to engage in pro-social behavior and incorporate the student body and community whenever possible. One way of modeling …
The Legacy Of Mining In Southwest Missouri: Past And Present Conditions Of The Tri-State Mining District, Anastasia M C Mcclanahan
The Legacy Of Mining In Southwest Missouri: Past And Present Conditions Of The Tri-State Mining District, Anastasia M C Mcclanahan
MSU Graduate Theses
The historic Tri-State Mining District (TSMD) of southwestern Missouri, southeastern Kansas, and northeastern Oklahoma has a history of lead and zinc mining that extended over a hundred years. During the district’s peak production period, the TSMD was one of the world’s largest producers of lead and zinc. The mining activities in the TSMD produced economic growth that supported the local communities and were essential to the victory of the Allied Forces during World War I and World War II. Beginning in the 1920s, the mining activities in the district slowly began to cease due to depletion of metal ores and …
Geochemical Fractionation, Speciation, And Bioavailability Of Heavy Metals In Stream Sediments In Aurora, Mo, Miles Pearson
Geochemical Fractionation, Speciation, And Bioavailability Of Heavy Metals In Stream Sediments In Aurora, Mo, Miles Pearson
MSU Graduate Theses
Stream sediments from Chat Creek in Aurora, MO, part of the former Tristate Mining District, were digested via a sequential extraction procedure modeled after the Tessier method. Prior sampling had shown elevated levels of zinc, lead, and cadmium in sediments located near former chat piles. Metals in sediments were divided into four geochemical fractions: 1) easily exchangeable, 2) carbonate-bound, 3) iron-manganese oxides-bound, and 4) organic matter-bound. The distribution of the metals within these fractions can help predict the bioavailability and speciation of said metals. The majority of metals were contained in the third and to a lesser extent the fourth …
Channel Sediment And Mining-Lead Storage In Flat River Creek, Old Lead Belt, Missouri, Ralph Joseph Hill
Channel Sediment And Mining-Lead Storage In Flat River Creek, Old Lead Belt, Missouri, Ralph Joseph Hill
MSU Graduate Theses
Historical mining for lead (Pb) in the Old Lead Belt District introduced large volumes of tailings into nearby streams resulting in the large-scale contamination of channel bed and bar deposits in Big River which drains the southeastern Missouri Ozarks. Tailings pile sites have been remediated so that present contamination sources to the river are primarily from the remobilization of Pb stored in channel and floodplain deposits. This study examined the channel geomorphology and sediment geochemistry of Flat River Creek (FRC), a major tributary to the Big River which drains an area that includes three of the six major mines in …
