If the bacteria enter the small intestine, they use their flagella to propel themselves through the lining of the intestinal wall, they produce a toxic protein. One part binds to specific carbohydrate receptors on cell-surface membrane; the toxic part enters the epithelial cells. This causes ion channels to open and Chloride ions flood into the lumen of intestine. Water then follows them into the lumen which causes watery faeces (diarrhoea) and dehydration4. Because of the improvements in sanitation and hygiene in the last 100 years, Cholera has been wiped out of England and much of the rest of the world3.
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
The bacteria commonly exist in rivers and lakes, are often found in any warm water system or device; air conditioning cooling towers, whirlpool spas, humidifiers, faucets and shower heads, anywhere artificial water is being supplied or used, and any place where water is stagnant. People contract Legionnaires by inhaling small droplets of the contaminated water. The disease has not been proven to pass from person to person. The likely hood of contracting the disease depends on the level of contamination of the source, health and age of the person exposed, and the intensity of the exposure. Most cases are a single isolated case, but outbreaks may occur.
Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process. During the drilling process, wells for drinking water may become polluted with a variety of contaminants, such as methane gas. Here I have a video showing exactly what the drilling is doing to peoples water supply. Gas wells require miles of roads and pipelines to move the natural gas from the drilling site to the market. Construction of these transportation corridors can break up the natural landscape and impact wildlife habitat.
Lake Huron is one of the Great Lakes and a major part of our fresh water system, which contains many wildlife and species. The lake however, is in a real danger, adversely effecting habitats, fish, wildlife, and human lives. Lake Huron has become a dumping ground for many companies, dumping waste that contains many pollutants. Bacteria levels have increased in the lake which can cause serious illness. These pollutants have reduced water quality, contaminated soils, and damaged the Lake’s ecosystems.
What caused this? Today I will have a chance to explain some of my ideas. To support these theories I will mention some documents to help in the essay, so let’s get started. [Doc.A] States: “…Adjacent river and creeks became brackish as water levels rose, reliable sources became scarce…as saltwater transfusion caused introduced filth tended to linger rather than wash away.” This may have caused the colonists to become sick. As the reliable water sources shrank and they were forced to drink the contaminated water.
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
Chemical Mixing * Potential for indirect chemical release into water supply through surface spills or leaks 3. Well Injection * Potential for more direct contamination of water supply by surface spills or leaks 4. Flowback and Produced Water (Wastewaters) * Again, potential for direct contamination of water supply by surface spills or leaks 5. Wastewater Treatment and Waste Disposal * Inadequate treatment of wastewater could allow contaminants to reach drinking water and surface water * Byproducts formed by reaction of hydraulic fracturing contaminants with disinfectants It should be noted that a majority of these potentialities fall under the category of “human error”. It should also be noted that a majority of ANY potential failure in a system falls under that same category.
Each of these compounds is known to be poisonous, cancerous, or cause birth defects. The EPA fears that the drinking water will compromised due to runoff of the surface water discharge. Additionally, contamination of underground sources of drinking water and inadequate treatment of the waste water are possible. The threat of contaminated water supplies can cause a fearful population, largely due to the propaganda spread by anti-fracking initiatives. Although there are potential economical disadvantages to fracking, there are also enormous positives.
Hematuria may continue for one day or last several days. Urinary tract infections are fairly common and result from bacteria entering the urethra and typically infecting the bladder but may spread to the kidneys as well. Urgency and frequency of urination may also be a complication with the presence of a UTI (urinary tract infection). Kidney stones can be another symptom of PKD. Cysts may block the tubules and prevent normal drainage
