CONTROLLED BREEDING AND SELECTION OF RESISTANT SPECIES Aegagropila linnaei and Taxiphyllum Barbieri FOR PREVENTING PETROLEUM BASED POLLUTION IN FRESH WATER RESOURCES

Water issue adressed: Too dirty
PETROLEUM BASED POLLUTION

One of the most important issues in the world is water pollution. This pollution may have occurred because of industrial products such as petroleum. Lots of sea and fresh water resources such as rivers and lakes are in danger because of this problem. Also, lots of living things’ health is being threatened by this pollution. In our project we chose two species which are “Aegagropila linnaei” and “Taxiphyllum barbieri“. These species are durable and resistant to diesel. We aimed for these species to be reproduced in a polluted environment.

This is how I came up with the idea for this project:

Today, with the effect of both global warming and the increase of manmade pollutants, our clean fresh water resources are decreasing and becoming polluted day by day. Especially in recent years, thousands of square kilometers of ocean and sea water have been polluted as the result of accidents occurring in the world's largest oil production platforms. The same is true for fresh water sources, with waste being directed to fresh water sources. In our project, we wanted to reproduce a type of species that can ensure the continuity of aquatic life in polluted fresh water sources caused directly by petroleum and petroleum products. To ensure the selection of this species, we have exposed these species to the petroleum product in various proportions to create the most durable and strongest colony. In our study, by selecting two species that can grow and excist both on the surface of the water and just below the surface, we aimed to create colonies that can survive even if the petroleum product surrounds them.

CONTROLLED BREEDING AND SELECTION OF RESISTANT SPECIES Aegagropila linnaei and Taxiphyllum Barbieri FOR PREVENTING PETROLEUM BASED POLLUTION IN FRESH WATER RESOURCES One of the most important issues in the world is water pollution. This pollution may have occurred because of industrial products such as petroleum. Lots of sea and fresh water resources such as rivers and lakes are in danger because of this problem. Also, lots of living things' health is being threatened by this pollution. In our project we chose two species which are "Aegagropila linnaei" and "Taxiphyllum barbieri". These species are durable and resistant to diesel. We aimed for these species to be reproduced in a polluted environment. Our project consists of four processes: 1. Cultivating and the reproduction of these species in stable conditions, 2. Preparation of an experiment which consisted of adding 50 and 100 μl of diesel to 200 ml clean fresh water. And adapting them to a polluted enviroment, 3. Taking measurements of the colonies which have adapted to diesel, 4. Lastly, the selection of the strongest and best colony in the polluted environment. We repeated this experiment three times and the analyses were plotted with MATLAB® program. The highest strength was concluded as "Taxiphllum barbieri". A colony which has the same growth value as the control groups and was selected from the 100 μl diesel environment, has confirmed both the entire study and the targeted project to be successful. Lastly, we designed a plastic tank from a 3D printer to provide the controlled oscillation of the selected colony. Key words: Fresh water resources, Selection, "Aegagropila linnaei -Taxiphyllum barbieri", Petroleum products.
