How do human activity pollutants like car gasoline and waste cooking oil affect the pH and oxygen levels in water bodies consisting of the water plant Elodea? (Which can be correlated with Lake Pollution in Ankara)

Abstract

Having lived in Ankara, I have always appreciated the scenic views of the lakes which are important natural features and recreational areas for the people. However, On my last trip to Lake Mogan in Ankara, I noticed an alarming layer of oil floating on the surface of the water, as well as a mild smell of petrol. Locals told me that the lake, which was once teeming with life, had fallen victim to pollution from the surrounding city, including the careless dumping of used cooking oil and road runoff containing petrol. This made me think about how these seemingly benign, everyday pollutants could be major issues for fragile aquatic environments. In particular, I found myself wondering about their effects on the more basic quality indicators of water, such as pH and concentration of oxygen, which are important for the existence of aquatic vascular plants like Elodea
