Two sources of Ipomea Aquatica were subjected to 10 different concentrations of mercury under experimental conditions. Data was gathered from an experimental period of one week for the lenght of leaves, length of roots, number of leaves, number of roots, and survival of stalks. Statistical treatment of the different parameters against the concentrations showed no significant difference between the two sources. There was also a pattern in the relationship of the two. A concentration increases, the parameter decreases. A chemical analysis was done to qualify the amount of mercury absorbed in the leaves, stems, and stalks of the plant. There seemed to be no affinity by mercury to any apecific part in the plant.
