An experiment volition be conducted to show how dangerous phosphates substructure be to an aquatic environment. This topic is important because phosphates are in many soap and detergent products that a lot of hoi polloi use ein truth day and then is dumped in to bodies of rattling water. If the nutrient phosphate is added to the tank of duckweed, the duckweed go away grow. There will be algal blooms and when the algae die there will be more algae for aerobic bacteria to scatter and as a result there will be less dissolved oxygen.
Duckweed that is utilise in this experiment is called low Lemma. It is the smallest flowering plant. It is indigenous to the United States of America. It floats on the water climb in a green layer (Toxics, 2004)
There are many shipway that phosphates involve in to lakes and ponds. As very clearly stated in the Figure 2, the United States produces oodles of phosphates, more than any other country in the knowledge domain of 2001. It is referred to phosphoric acids as well. There are many ways phosphates loafer enter fresh water environments such as sewage, many kinds of soaps, antifreezes, fertilizers, and latex paints. These may be directly dumped into bodies of water, save more into the streams. Figure 3 shows how phosphates are used in different products most of these products every day in theses .



consort to figure 3 detergent is the second most used item frankincense it is use in this experiment .
very small amounts of phosphates can noticeably affect the growth of plants. Amounts as small as 0.01 mg/L can work out the growth of all aquatic plants in an area and thus phosphates will be used in that amount for in this experiment (Bentler,2004). The duckweed consumes much of the available oxygen. The lack of oxygen can cause severe occupations for aquatic animals. And phosphates only make this problem worse.
fade out oxygen (DO) refers to oxygen that is dissolved in water. Dissolved oxygen is what fish breathe. According to Author (year), a meanness of 5 mg/L DO is...If you want to get a full essay, order it on our website: Orderessay
