Abstract
Environmental pollution is a big problem in today’s world. Every passing year, the needs of mankind, technology and industrialization increases on high rates. This increase brings with a high amount of consumptions especially in developed countries. Iron and metal industries are also a part of this consumption. After giving shape to those metals, cooling them is the follower step. Tons of water is used for this cooling process and high amount of ammonia ions mixed in those waters. These ammonia ions can cause toxic effect for living organisms in water environments. This experiment focused on the toxic effect of ammonia ions on the Elodea canedensis and dealt with the research question, “How does the amount of ammonia ions mixed in environment by mining industry wastewaters effect the photosynthesis rates of E. canedensis? The plant used in this experiment was Elodea canedensis. Identical pieces of an E. canedensis are placed in 500 ml beaker glasses. Increasing amounts of liquid ammonia solutions are placed to five different groups and observed for 4 days. 5 trials are made for each group than the data are recorded. 2.6 ml/ 5.6 ml/ 8.6 ml/ 11.6 ml/ 14.6 ml ammonia ions are added to the beaker glasses of groups 1, 2, 3, 4, and 5 respectively. In order to observe the photosynthesis rate, E. canedensis plants are placed under a test tube filled with water by the help of a funnel. Oxygen gas released by photosynthesis will make a pressure in the test tubes and by this way the water level will decrease and photosynthesis levels of different groups can be observed. . The results of this experiment supported my hypothesis that stated the increasing the ammonia ion concentration will decrease the photosynthesis level which proved the toxic effect of ammonia on aquatic environments.
