Abstract
Heavy metal pollution in bodies of water has become a major problem in major industrial areas, such as China. Pollution is often hard to clean up due to the major expenses and dangers to local flora and fauna that are not already affected. An alternate solution to counter heavy metal pollution in the form of aluminum nitrate is proposed: citric acid, which was hypothesized to neutralize the basic aluminum nitrate. Lemna minor, also known as duckweed, was placed in bowls to both simulate a water environment and to act as an indicator of the toxicity of the water. The bowls were filled with citric acid solution of varying concentrations and half of the bowls were given aluminum nitrate to act as water pollution. Since duckweed is too small to be feasibly separated into specific numbers, the duckweed growth was measured by taking the initial amount and finding the difference between the final sample. The mean differences of each treatment was analyzed using ANOVA at alpha = 0.05 level. There was significant differences among the treatments F (9, 27) = 28.44, p < 0.001. Results also indicated that citric acid was detrimental toward the growth of the Lemna, and that the combination of both citric acid and aluminum nitrate grew the Lemna better than citric acid by itself. /
