  • Essay / Cyanobacteria and Their Effects on Algal Blooms - 774

    Objective: To determine the effect of agricultural runoff on the environment and to find solutions to reverse any damage.Introduction: There are many different species of algae. One of the most common algae, blue-green algae, is a type of cyanobacteria. One such species is Chlorella regulararis, a single-celled algae that stays alive through the process of photosynthesis. Algae growth depends on various factors, such as the nutrients present in that environment, temperature, light levels, turbidity, and stable conditions. (Department of Primary Industries, 2009). The massive growth of algae is known as an algal bloom. This large population has negative effects on the surrounding environment. In studies conducted at Stanford University in 2005 (Stanford Report, 2005), algae blooms were linked to the spread of pollution from agricultural runoff, with the high levels of nitrogen/phosphorus used in agriculture. spreading of fertilizers. to these water sources, thereby increasing algae levels. Nitrogen, for example, helps the chlorophyll in algae photosynthesize at an increased rate, causing them to reproduce at a faster rate (Douma, 2008). Algae blooms are not a new phenomenon, with the first occurrence in the world dating back to 1878 in the South. Australia. In recent years, the number of these algal blooms has increased, with much larger areas than ever filled with these blooms. Research by the Smithsonian Institute found that in some areas, water could go years without any contamination, but within days of agricultural runoff reaching the ecosystem, high levels of algae blooms were observed . Common fertilizers contain high levels of phosphorus and nitrogen, this is what a factory needs to produce more paper......for drinking water, this would lead to water contamination. It remains to be determined whether this solution would be beneficial or not. Algal blooms pose a huge environmental risk, with massive outbreaks devastating for many stakeholders. In late 1991, an infamous boom stained 1,000km of the Darling-Barwon river system, causing the death of 1,600 sheep. This ultimately led to an increase in research into these cyanobacterial blooms, which allowed the development of certain types of prevention methods. (Avolio, 2013). Repairing the damage can take months or even days, and some sources of standing water take even longer to repair because the same water is in the exact same place. Assumption: Solutions will not completely restore the environment. an appropriate state and will be unable to accurately reverse the damage caused by pollution.
