19 Jul AN INVESTIGATION INTO THE EFFECT OF IBUPROFEN ON CHLORELLA PYRENOIDOSA GROWTH
Increased urbanisation and population have led to higher medicine concentrations detected in water systems worldwide. This study investigates the effect of one of the most widely pollutant medicines (ibuprofen) on Chlorella pyrenoidosa as a model for other microalgae and higher plants. A colorimeter set to 440 nm was used to measure the effect of ibuprofen concentrations Chlorella growth over 11 days. Possible experimental error made it difficult to determine a trend over time, however, when comparing the concentrations to each other on the last day of testing it was found that the 0.4µg/L concentration had the most growth and the 0.0µg/L the least. This indicates that ibuprofen could cause eutrophication, however further investigation is necessary to adequately determine this risk.
