A study was conducted to determine which of the two plants, Water Hyacinth and Water Lettuce absorbs more cadmium in water three treatments: To without cadmium poured in both plants, T₁5.25 mL of Cadmium was poured in Water Hyacinth, T2 5.25 mL of Cadmium was poured in Water Hyacinth. This study used RCBD (Randomized Complete Block Design) with three treatments and three replications. The water lettuce and water hyacinth were climatized within one day so that both plants can adapt to their new environment. After that one day, the cadmium was poured in treatment 1 of both water lettuce and water hyacinth. All treatments were stirred within the interval of 12 hours so that the cadmiurn will not settle down at the bottom of the pail and researchers can get the accurate amount of cadmium in every treatments and replicates. Researchers got the samples in the middle part of every pail at the same time and measurement. Researchers got water samples in Day 1, Day 3, and Day 5.
The data collected using ANOVA proved that there is no significant difference between the days of water lettuce. There is a significant difference between the days of water hyacinth so T-test was used to determine the significant difference between the variables. The T- tabulated was ±2.776, the result for Day 1 vs Day 3 was 1.542, Day 3 vs Day 5 was 1.552 and Day 1 vsDay5 was 2.753. This means that the null hypothesis was accepted and there is no significant difference between each variable.
Based on the findings obtained from the study, the researchers concluded that water hyacinth absorbed more cadmiurn in water than water lettuce because of the results shown in Results and Discussion section.
Based on the findings and conclusion of the study, the following recommendations are hereby suggested:
1. Use other aquatic plants that have an ability to absorb toxins;
2. Use other toxins that can be found in different bodies of water.
3. Further study may be conducted with the same procedure but the plant itself will be tested instead of water.
4. The same procedure may be conducted but the experiment will be performed on land to determine whether phytoremediation is also effective in absorbing toxins in land by the use of other plants with the same size, number of leaves and the same height, and
5. Use other methods for the comparison of both plants.
