INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in water harsh (3). They are both common pollutants found in fresh water systems throughout the world.

He was so very poor that he got his living through planting in his small backyard. He was the only human‚ living in the forest but he has many animals who lives with him. One day‚ Jack

phytoremediation. Duckweed is often used for this purpose in order to decrease nutrient content in water‚ this would therefore increase Duckweed plant growth but since it is used as feed for animals‚ it can be gathered and used for that purpose. In this way eutrophication levels are decreased in water sources and there is more food

Biogeochemical Cycles and Human Impacts The carbon cycle‚ nitrogen cycle‚ and phosphorus cycle all play a big role in our environment. They are some of the key components that are recycled to create pathways know as the biogeochemical cycles. All the chemical elements that make up living cells must be recycled continuously in order for the living components of a major ecosystem to survive. The recycling of these elements is the only possible way to maintain a dynamic system. Human impacts

and transports it into the bodies of water. These fertilizers contain nitrate and phosphate. When the nitrate and phosphate are put into the water‚ they cause a massive growth of algae‚ called eutrophication.( Lentech‚ 2016) The excess algae causes the water to turn green. As a result of eutrophication‚ there is not enough oxygen in the water. This is because when the algae die‚ the bacteria that decomposes it‚ takes up oxygen. With more algae reproducing‚ there is a greater quantity

some of the pollution; most of the pollution is caused from fertilizer on fields‚ agricultural runoff‚ and city sewer plants. “As a result of these pollutants‚ Lake Erie contained increased levels of phosphorus and nitrogen‚ which contributed to eutrophication a process that encourages the development of algal blooms.” (Rotman) People started to figure out that they needed to do something about this algae bloom problem so they wanted to make laws and acts that would apply. Some laws they made were

much further impacting a larger area. Both gaseous and particulate ammonia contribute to eutrophication of surface waters‚ soil acidification‚ fertilization of vegetation‚ changes in ecosystems ‚and smog and decreased visibility in case of major gas . Eutrophication Eutrophication is a result of nutrient pollution (from deposition or run-off) into natural waters (creeks‚ rivers‚ ponds‚ or lakes). Eutrophication generally promotes excessive plant growth and decay‚ favors certain weedy species over

Prior to the Riverwatch Trip I was skeptical as to how much the wastewater treatment facilities in Calgary contributed to the wellness and overall health of the Bow River. However‚ through various tests before and after the treated water has been combined with the river water‚ I concluded that the wastewater facilities are well worth the tax dollars. Calgary is a large city of over 1 million people and as such produces an abundance of waste which should cause nitrate levels in the water to go up
