Environmentalists are worried about the ecological effect of heavy metals released by industrial and domestic waste contaminants. The objective of this project is to examine the effect of heavy metal contaminants on a common freshwater plant, Brazilian Elodea (a.k.a. Egeria Densa). The approach of the experiment is to use Lead (II) Nitrate, Pb(NO3)2 and Copper (II) Nitrate, Cu(NO3)2 as water contaminants. From the observation of cell structures and the stems of the Brazilian Elodeas living in copper (II) nitrate and lead (II) nitrate comparing to the clear water trials, we proved the two heavy metals are harmful to aquatic plants.
