Assignment #3.1 “Determining Causes and Effects-Draft Version” “Determining the Causes and Effects of Water Pollution in Lake Huron” By: Maricel N. Johnson November 28, 2012 Eng 115 (Tuesday Class) Professor: Michael Hunter Lake Huron is the third largest of the lakes with 3,540 feet of water, with it’s average depth is 195 feet and with maximum depth of 750 feet. The Great Lakes, Lake Michigan, Erie, Ontario, Superior and Huron are our largest freshwater system. Lake Huron contains many wildlife and is in danger of being polluted. This pollution is harmful to fish, wildlife animals, and to humans of the region. Determining the cause and effects of water pollution in Lake Huron contributes to finding solutions for cleaning up our waterways and improving public health.
C. Fishing in lakes and ponds is a good place to start because they are great places for fish to live. They produce abundant plant food and offer plenty of cover for fish to hide. Shoreline structures like docks, logs, stumps, brush and rocks provide shelter, shade and protection for fish. All of which means lakes and ponds are prime fishing spots. III.
Oso De Oro Park is located on NW Barstow and Forkner. Visitors will be greeted by a Margaret Hudson California Grizzly Bear sculpture at the park entrance. A plaque next to the gate reads SLOAN JOHNSON OSO DE ORO LAKE PARK, June 1995. The park is about nine acres and its features include: Full time park attendant, picnic pavilions, two main play structures, wheelchair accessible basketball court, raised grass area, one lake and a few docks. “Because the park is an excavated storm water retention basin, its features are arrayed at three different elevations.” The upper street level tier provides picnic as well as little and big kids play area.
Questions on “The Furbish Lousewort- Weed, Weapon, or Wonder” 1. Macior’s viewpoint is a biocentric viewpoint. He views this plant as valuable due to its life history. Through his studies in his Plant Geography course at the University of Wisconsin-Madison, he first learned of the endemic distribution of Pedicularis Furbishae, or in other words, the fact that it’s species is confined to a small, particular area. In 1977, after discovering that Pedicularis Furbishae was on the endangered status, Macior began working in collaboration with the US Army Corps of Engineers and the Fish and Wildlife services to conduct field and laboratory research with a focus on preserving Pedicularis Furbishae.
It was also stated by Professor Bob Prior that “it is possible for salt to hurt an enzyme due to the fact that salt can change the polarity of certain parts of an enzyme.” Over time, salt tends to denature certain enzymes, making them less efficient catalysts. This is one of the key reasons that our hypothesis states tha salt will cause the enzyme to be less effectual. Our lab group felt compelled to find an answer. We used Morton's Sea Salt in our experiment because the Morton Company has been in the salt business for over 160 years. They have a very informative website in which we were able to resource valuable information on the differences of sea and table salt (Mortonsalt.com).
I gained valuable hands-on field experience analyzing and studying the pollution of microplastics in the Puget Sound of Washington state and studied nutrient cycling in alpine and urban lakes. With this experience I hoped to gain employment in the environmental field upon graduation. Entering the job hunt after graduation, I realized that I needed much more than experience to stand out as a strong applicant; I needed to further my education with a graduate degree. I look forward to a career in civil engineering where I can not only use my academic background to achieve my long term goals but also make scientific contributions to my field of interest in water quality. I believe that graduate studies would provide me with the opportunities to attend advanced courses and be the stepping stone to my career in civil engineering.
1). In addition to the mobility and contamination of water, atrazine is also a potent endocrine disruptor active in the parts per billion range in fish, amphibians, reptiles, and human cell lines (Hayes et al. 1). The use of atrazine has been described by Heather Hamlin, an assistant professor with the University of Maine, School of Marine Sciences, as being responsible for a host of health problems seen in fresh water fish and amphibians (Hamlin 1). Research has shown that atrazine in water gravely affects male frogs by decreasing testosterone levels (Hayes et al.
The Indiana Dunes are well known by biologists around the world as the “birthplace of ecology.” This is likely due to them being a prime example of ecological succession, which can be seen occurring as one walks through the different areas of the dunes from the beach all the way through the woods. Originally, the dunes region was covered by a massive glacier in what is now the Great Lakes region, but as the Earth warmed up the glacier melted and left a heavy layer of sand. In the dunes community, sand is the base material on which ecological succession occurs. Ecological succession is the reason why the Indiana Dunes State Park is what it is today, although tolerance curves along with key plant species drive the process itself. Ecological
SPS: To inform my audience on the dangers of bottled water companies on the environment, and our society. Thesis: Use third party sources to reveal where bottled water comes from, who regulates it, and the negative impact its factories and waste have on our environment and ourselves. I: Intro: AGD: How many people here drink bottled water? Well according to the documentary “Tapped” by Stephanie Soechtig, 40% of all bottled water is just recycled municipal tap water. Aka, the exact same thing that comes out of your faucet.
CADMIUM POLLUTION AND ANTHROPOLOGY by Courtney Van Gemert Cadmium toxixicity is of great concern to the world anthropologically. Cadmium is an element existing naturally in minute concentrations across terrestrial and marine environments, but greater excess levels observed are almost entirely anthropogenically introduced. Though cadmium has favorable chemical and physical properties conducive to wide use in special alloys, stabilizers, in rechargeable nickel-cadmium batteries, and as a control rod material in nuclear reactors, it is a toxic heavy metal of increasing environmental concern due to its wide variety of adverse effects [1]. Cadmium is harmful to various organs, from kidneys to the central nervous system in vertebrates, including humans. In fish, neurological functions, intermediary metabolism, antioxidant activity, epithelial transport, and other physiological and biochemical systems are damaged by cadmium [2].All of these harmful bioinorganic effects are largely due to occupational or environmental exposure to in-excess levels of cadmium through inhalation or ingestion of fine air particulates and consumption of cadmium-exposed plants, animals, or water.
