The first and foremost is the oil spillage in the ocean which leads to ocean acidification. This brings a huge threat towards the environment and the marine wildlife. Oil operation in sea bed often requires drilling fluids such as mud which are used to inject into the wellbore to lubricate the drilling bit. These devastating effects of numerous oil spills on the surface of the ocean could bring a long term environmental effect to the coastal areas as well as to the sea bed. Besides, drilling mud which contains toxic substances like benzene, zinc, arsenic, radioactive materials, and other contaminants are used to lubricate drill bits and maintain the pressure in the drill.
If human being consumes these contaminated organisms, toxic compound will be accumulated in human body. Deeper approach of natural science such as biomedicine is important related to marine contamination. Biomedicine knowledge particularly in anatomical, physiological, genetic and biochemical models are proven to be very useful to explain the impact of contamination in life organisms in marine ecosystem. Furthermore, it can also develop explanation about what kind of disease that might be created because of the toxic compound entering the food chain (Hansen, 2007). For example is the case of Minamata in Niigata prefecture, Japan, where heavy metals produced by chemical factories pollute marine area can enter the food chain and accumulate in marine organism and even human
This will affect drinking water, irrigation, and fisheries, according to researchers from AJOL. High amounts of lead were also being deposited at one of the sites, well above the recommended amount. This will lead to lead being built up where the waste is disposed, and that isn’t good for drinking water, or marine organisms. They also found that cadmium was being released into the water, which can be toxic to fish, and carcinogenic to people. High levels of potassium were also found, which can be dangerous if too much is present in drinking water.
When water reaches their life cycle it will end up in the ocean because water falls from the river to the ocean. Scientist believes that maintain clean water and preventing pollution from the ocean could expand and maintain the earth ecosystem. One major problem beside the pollution in the ocean is the spill of oil. Why it’s dangerous? Because oil is conclude as an inorganic substance, which cannot tolerate and bound to
As demand for metals and other materials grow in economy, countries turn to the ocean for collecting these materials that may occur more readily in the ocean floor. As informed by conserve-energy-future.com, the deepest parts of the ocean are being affected the worst by the mining; and acidity is increased due to the materials polluting the water: “For example, copper is a major source of pollutant in the ocean and can interfere with the life cycles of numerous marine organisms and life.”. They also state that as the acidity increases, corrosion of man-made objects is inevitable, leading to more pollution due to degrading material and increased oil spills. This then leaves another overcast of deadly substances to hinder the lives of creatures that must endure the circumstances placed by human
Bailey McTigue Professor Wick ENC 1102 Writing and Rhetoric 13 February 2018 Water Pollution An Annotated Bibliography Critical Preface The problem that I care to research about is water pollution. As an environmentalist and someone who cares about the environment, I understand that water pollution is a big deal. I have always loved to research things that humans do to damage the environment. A cause of water pollution is oil spills from big oil tankers. Oil gets into the water and kills the marine life.
When pH is high which means more OH⁻, then aluminum ions will react with hydroxide ions to form aluminum hydroxide. Phosphate ions are acting as a natural buffer. If the equipment is not washed with acid, it would cause an error. This is because the phosphorus analyzing is dealing with low concentration of phosphorus and it is easily contaminated by detergent and other chemicals and it has to be washed by using an acid and also it has to be rinsed with distilled water once it is rinsed with acid. Also refer to section 4 (discussion).
Exploration, transportation, and exploitation of crude oil can cause marine and terrestrial oil pollution. Oil spill is harmfull for marine environment. Lead (Pb) and Cadmium (Cd) in gasoline are the examples of heavy metal that are usually contained in gasoline and it can be stick and make soil is contaminant. Thus, the industrial waste needs a
Thirdly, the ocean and its inhabitants are greatly affected by marine pollution. Marine pollution is the entrance of hazardous materials into the ocean. The ocean can be polluted a number of ways, including garbage, sewage, and noise. Garbage pollutes the ocean by disturbing marine life and tarnishing the marine environment, it can also damage ships. Sewage pollutes by adding dangerous chemicals to the ocean and depleting oxygen used by the animals.
Discussion: Marine Debris, also known as marine trash is man-made waste that is released into oceans and coastal waters due to human activities. Marine debris brings up many environmental problems to both humans and the marine ecosystem. According to Ocean Conservancy (2014), the common types of marine debris collected include cigarette butts, food wrappers, beverage bottles and cans, plastic bags, straws and glass bottles. Although these wastes seem to come from offshore activities, studies suggest only 20% of the pollution comes from ships or offshore platforms, the rest originates from land-based activities (Sheavly & Register, 2007). We will discuss the causation and effects of marine debris and propose solutions to mitigate marine litter issue in Singapore.
However, it 's not only just because of man-made reasons. The coastal marshes disappearing can also be affected by natural causes. Sediment is being deposited into a river delta increasing the weight, which causes the entire area to sink (p. 11). Depositing may sound like a positive cause, but however if the course of the sediment changes then no new sediment will continue to be deposited. Another natural cause is oceans and hurricanes.
The Puget Sound is polluted, largely because of people’s actions. Efforts to clean up pollution are already underway, but the problem of pollution still persists. The Department of Ecology says that “a major contributor of these toxic pollutants entering the Sound is the stormwater that runs off our highways, roads, driveways, roofs, parking lots, disturbed soils, and other developed surfaces” (“Threats to Puget Sound”). When there is rain, the rain
Discussions and Findings What impact are chemicals currently having on Corals and fish species on the Great Barrier Reef? The impacts of chemicals on the Great Barrier Reef are far beyond what is first expected. The reef is subject to effects of sediment, nutrients and chemical pollutants that currently effect 25% of the worlds coral reefs (Amelia S. Wenger, 2015), including the Great Barrier Reef. These three effects result in a decline in water quality, which is due to an increase in nutrients caused by fertilisers, herbicides, insecticides and sewage. This particular cause for water quality results in the increase and spread of algae and other organisms that compete with coral (Amelia S. Wenger, 2015).
