Post Industrial Revolution: The Cause Of Water Pollution

Decent Essays
Before the industrial revolution, contamination of water came from waste products from human and animals. In the 19th century relatively small amounts of organic and metal materials were in production. Post industrial revolution production of metals was on a large scale and burning coal was more predominant (Cullers). Industrialization in human society has continued to increase over the decades leading to more water pollution. Humans have been studied to put over 8 million tons of marine litter and pollution into the ocean each year (Parker). This pollution comes in many forms, whether it is plastic, oil, garbage, or motor vehicle emissions. The largest contributor of oceanic pollution comes from land-based sources. Land-based sources include…show more content…
When pollutants enter ecosystems varying effects can occur. New plant life can be introduced from aquatic pollutants as well as vegetation being killed. Speciation occurs by waste providing nutrients and changing the growing conditions. In contraire, growing changes by lowering or raising pH kills vegetation. Other than pollutants, debris such as garbage – accumulates at the surface of the ocean and blocks sunlight from reaching deeper aquatic flora. Lack of sunlight suffocates the plants causing de-oxygenation of the ocean. De-oxygenation causes dead zones in the ocean, which are increasing in sizes and numbers as more pollution occurs (U.S. Pure Water). Sunlight is the key force behind photosynthesis, which creates glucose food molecules. If marine debris blocks the sun it prevents glucose production, stunting growth and thus creating dead zones (Seattle PI). An additive to the causation of dead zones is from fertilizers from agricultural use. Phosphorus and nitrogen rich fertilizers pollute waterways from agricultural runoff. These nutrient rich waters are a source for algae to bloom. Algae in polluted waters then lead to deoxygenated dead zones. However, to mitigate this risk, seaweed can be planted to soak up excess nutrients before dead zones can form (St. John’s River Water Management District). Furthermore to marine debris, heavy metals pose a dangerous effect to marine…show more content…
Heavy metals such as Zn, Fe, Co, Cu, Cr, Mn, and Ni are bio-accumulative and are stable in ecosystems. These elements are needed for metabolism in small doses. If said elements accumulate too high they cause toxic effects. Toxicity of these elements causes an environmental concern (Sharma). Causes of accumulations of heavy metals are caused by rapid industrialization. This pollution causes an environmental threat to aquatic organisms, due to the toxic effects in the food chain (Majumder). Cyanobacteria are the primary organisms affected by heavy metals. Challenged by toxic oxygen species, cyanobacteria produce photosynthetic electrons that are exceeded in their assimilation of inorganic nutrients. Metals affect growth, which are consistently being spread out in the environment due to human activities. Corrine, C. & Franck, C.). Said metals cannot be degraded and high levels in cyanobacteria affect the food chain. Cyanobacteria are vital in aquatic communities as they provide oxygen, which is a source of life for phytoplankton. Once the phytoplankton eats the cyanobacteria, zooplanktons eat the phytoplankton. Metal concentration in tissues are raised each step up on the food chain; A study by Kafkas University uncovered. Magnification of toxic metals that bio accumulate throughout the food chain are heavily prevalent in fish. Researchers in Tanzania have noted that metal concentrations in
