EXECUTIVE SUMMARY: The study aimed to determine the phytoremediation potential of phragmites australis (cav.) trin. (tambo) based on its lead (pb) accumulation. The study was conducted at the university of rizal system morong campus, morong, rizal during the school year 2017-2018. The study made use of the descriptive design since it helps to determine and prove the phytoremediation potential of tambo plant based on the possible presence of lead. The researchers prepared and harvested the tambo samples at the selected areas in university of rizal system, morong campus as well as the soil samples. The lead content was determined from the sample plant and soil using atomic absorption spectrophotometry. It was done at central analytical sevices laboratory in the university of the Philippines, los baños, laguna. To determine the amount of the pb accumulated in the soil and the tambo samples cultivated in different quadrants, mean and standard deviation was utilized. While in determining the calculated bio concentration factor formula was used. Meanwhile, t-test was use to determine the significant difference in the accumulated pb (lead) of the tambo plant from the different quadrants. On the hand chi-square was utilized on the significant difference in the bio concentration factor of the tambo plant form the said quadrants. Based on the calculated mean, soil from quadrant I, near the college of science's- science and technology building has the highest led content of 7.98, while the soil from the quadrant IV, near college of industrial technology, isr extension has the lowest mean which obtained a rate of 3.19. the findings also revealed that soil from quadrant II, near mrf and soil from quadrant III, near food court have a pb content of 3.26 and 6.03 ppm, respectively. On the other hand, the average mean in the post-test of pb content in tambo is 1.81 ppm. The findings also revealed that tambo from quadrant III, near food court has the highest lead content having a mean of 2.26 ppm, while the tambo form quadrant IV, near college of industrial technology, ISR extension has the lowest lead content which obtained a mean of 1.67 ppm. The result revealed that there is no significant difference in the pb accumulated in the tambo plant the different quadrants. While there is no significant difference of the bio concentration factor of the tambo plant from the different quadrants. Further, there is significant difference in accumulated pb of the tambo plant on the different quadrants. Moreover, there is no significant difference in the accumulated pb in the tambo plant on the different quadrants. The obtained results revealed that the soil from the selected quadrant of the university of rizal system, morong campus were safe to cultivate plants based on the 50 ppm standard lead on soil. Tambo plant cultivated from different quadrants have lead concentration between the normal ranges of 5-10 ppm. Tambo plant has phytoremediation property since the bioaccumulation factor (bcf) is less than 1 which means that plant is an excluder or not accumulator. Based on from the results of the analyzed data, it is then concluded that tambo has no phytoremediation potential.
