Background of the Study Water pollution has been considered as one of the primary destroyers of Earth’s environmental health. With the development of technology and industries, the bodies of water are left unclean. Few of the most alarming effects of water pollution are food contamination and disturbance in the food chain. Researchers have long been searching for answers for the elimination and prevention of water pollution, which will cost less than the usual and commercial methods used.

Hydraulic (Hydraulic vertically) is a holography. Hydraulic vertically, a profusely occurring submergence specie, has been found to thrive well in highly polluted water (Sinai, et al. , 1993). In addition, the plant has shown promise in the removal of heavy metals (Guppy and Candor, 1994). One of the most common heavy metals is mercury. Mercury Is a silvery-white poisonous heavy metal and is considered as one of the most dangerous metals. The entry of mercury In the food chain Is one of the problems today because our bodies easily absorb mercury.

The researchers alma to study the physical changes that will be brought about by mercury to Hydroxyl plants. B. Statement of the Problem Main Problem: Can mercury cause physical changes to Hydraulic plants? Sub Problems: 1) What are the physical characteristics of Hydraulic plants exposed in water with no mercury In terms of: a) leaf color b) leaf texture ; and c) new leaves? 2) What are the physical changes of Hydroxyl plants exposed In water with different concentrations of mercury in terms of: a) leaf color C. Objectives of the Study

This study aims to 1) determine if mercury causes changes in the physical appearance of Hydraulic plants 2) compare the physical features of Hydraulic plants planted in water with no mercury and with the one containing mercury D. Hypotheses of the Study 1) Mercury cannot cause changes In the physical appearance of Hydroxyl plants. 2) There will be no significant difference in the Hydraulic plants planted in water with no difference in the Hydraulic plants planted in water samples of different concentrations of mercury. E. Significance of the Study

The study aims to determine if mercury produces concentration-dependent hysterical changes to Hydraulic plants. If the research is proven true, future researchers can use the data and results as basis to support their study. In addition, it can be used to support the hypothesis that Hydraulic plants can be used as mercury-pollutant Indicator. With that, environmentalists, household members and students can use the plant as an alternative method in detecting mercury pollution of the water bodies. F. Scope and Limitations of the Study

The study was limited to the use of the Hydraulic plants found in ‘lagan City and the use of tap water for the water samples. The researchers limited their study to the use of inorganic form of mercury, murderous chloride. Furthermore, the study was limited to identifying the physical changes caused by mercury to Hydraulic plants and it excludes the potential of the plant to indicate how much mercury is present in the Neater samples and how much is absorbed by the plant. The researchers limited their study to the use of only one trial.
