Abstract
Acid rain is a growing problem with the continued industrialization of the better part of the world, especially in countries with little to no environmental regulation. The unnatural acidity can kill off local flora and as a result, disrupt the surrounding ecology. The purpose of the study is to study the interaction of different pH’s of simulated acid rain with Lemna minor, and see how increased pHs affect and damage duckweed. The hypothesis was that the 4.0 pH simulated acid rain would be the most damaging to the duckweed. Varying pH’s of simulated acid rain, which contained a 7:3 mix of nitric and sulfuric acid were added to an environment which contained duckweed. The amount of growth was measured for the duckweed as a way to gauge the sustainability of an aquatic environment after a spike in acidity. The mean differences of each treatment was analyzed using ANOVA at alpha = 0.05 level. There was statistical differences among the treatments at F(4, 34) = 6.46, p = 0.001. Results also indicated that the 4.0 pH treatment was the most damaging.
