Great Lakes Aquatic Health and Environment: Lake Ontario Abstract This paper critically analyzes the environmental factors that impact aquatic health in Lake Ontario. In total the nutrient availability and contamination in Lake Ontario has a large negative impact on the lives of the aquatic organism such as Quagga mussels, Cladophora and common fish species. Introduction The Great Lakes are a very important part of the fresh water system in the world. In fact, the fresh water in the Great Lakes accounts for approximately 1/5 of the world’s fresh surface water supply. The aquatic life and environment of the Great Lakes are a crucial factor when it comes to assessing the productivity and overall sustainability of the lakes.
Unfortunately exploiting the earth's petroleum resources has a serious environmental impact as the water gets contaminated and unfit for drinking until purified and oil reserves decrease which leads to scarcity of oil based products . Mining creates shocks and vibrations due to drilling and blasting activities which will lead to noise, dust and collapse of structures in surrounding inhabited areas. The ecology around the mining site will be disturbed causing loss of
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
And it’s important to study because Water is essential to life. Yet water pollution is one of the most serious ecological threats we face today. (Water Pollution) (The Importance of Clean Water) It affects to animals, humans, sea creatures. For humans, you will get a stomach ache at the least. (How Does Water Pollution Affect Humans?)
Companies producing products must get their materials from somewhere. Often if they must mine these materials, it’s done in a poor country where they can get away with unethical working conditions. Unethical working conditions are described as exposing workers to hazardous conditions (the mine could collapse, they breathe in toxic chemicals, etc. ), Many mining chains use child labor and put these children at risk, also chemicals released from mining cobalt get put into the atmosphere and are eventually absorbed into the soil or water around the mining site. It’s important for companies to prove that their product is or isn’t ethical because companies should be transparent about how their products are made.
AMD (Acid Mine Drainage) is created from sulfuric acid. It 's created when sulfuric acid makes contact with metals and other chemicals from the disposal site and then it creates AMD. Amd does many terrifying things to the environment like, it contaminates lakes, rivers, ponds, and other bodies of water. It also harms human health, fish, wildlife, and it also damages the entire ecosystem. Even the economy gets affected from sulfide mining.
Addition to these, disposal of dead bodies, discharge of industrial and sewage wastes and agricultural runoff, which are major cause of ecological damage and pose serious health hazards (Meitei et al., 2004a). The pollutant from agricultural lands such as fertilizers, pesticides and fungicides and from anthropogenic activities such as mining, disposal of toxic metals, human and animal faeces, industrial, domestic, municipal wastes are continuously discharged into river, such as Vaigai, are the major casues for deterioration of water quality (Karet al,2008 and Amman et al, 2002). In order to maintain the quality of drinking water, an essential component to humans and other living
One of the most important causes of Nile contamination is discharging of industrial facilities (Mohamed et al., 1998). Factory waste contains heavy metals such as, Zinc (Zn), Cadmium (Cd), Lead (Pb) and Copper (Cu), which cause toxicity. In this essay, the discussion will point to Nile contamination as a controversial issue and highlight some health problems which occur as consequences of using polluted water in Egypt. Likewise, the essay will raise some scientific methods to determine the percentage of heavy metal in water supported by example. Then it will suggest some chemical technical solutions to reduce the percentage of heavy metals in Nile and reuse it again for many purposes.
2.1. Soil contamination Occurrence of man-made actions is the main reason for soil pollution. The waste products which are coming from anthropologic are made of chemicals that are not originating from the environment which will finally lead to soil pollution. Manufacturing activities is one of the reasons for soil pollution, chemicals used in farming and incorrect removal of waste. Straight and unintended interaction with polluted soil leads to health risks.
Not only humans but also animals suffer greatly from air pollution, it effects the animal kingdom and ruins the wildlife cycle. Many species in the wildlife have been forced to move into a new harder habitat just because of air pollution. While burning fossil fuels harmful gases such as sulfur oxide and nitrogen oxide are emitted. When it rains water droplets are combined with Sulfur Oxide and Nitrogen Oxide to create a very harmful scenario which is acid rain. Acid rain can cause massive damage to humans, Animals and crops.
