Abstract

With the increase in food production, more pesticides have been released as a result of agricultural practices. This has had many adverse effects on the organisms present in water sources near the crops, as well as these freshwater ecosystems. The goal of our investigation was to determine the effect various harmful pesticides have on the primary producers and primary consumers in a freshwater ecosystem. We used Chlorella vulgaris as our primary producer and Daphnia magna as our primary consumers. We also used three pesticides: deltamethrin, an insecticide, propiconazole, a fungicide, and glyphosate, an herbicide. We tested for three different concentrations for each pesticide and a control, with twelve Chlorella and Daphnia samples. Over the course of five weeks, we measured the absorbance of the Chlorella at 550 nm, and over the course of three weeks, we measured the heart rate of the Daphnia.
