Abstract/Summary

Water pollution in the Pasig River is rampant due to industrialization. It brings adverse effects to both the environment and human beings. For this reason, various studies on the analysis of Pasig River's water quality have been made together with policies that may help in addressing the issue. In this study, water lilies are used as bioindicators for analyzing water quality in the Pasig River. Spatial analysis was used to measure correlation of heavy metal concentrations among locations and nonparametric techniques were used to compare metal contents in different parts of the water lily. Results showed that the heavy metal contents exhibit randomness in terms of their location. Differences in metal concentrations among bridges were detected and findings were used to classify mean elemental contents according to their similarities. On the average, Nagtahan Bridge and Makati-Mandaluyong Bridge were shown to be more polluted than Jones Bridge and Bambang Bridge. It was also concluded that elemental content varied depending on whether the epidermis or cross-section of a certain water lily part was being analyzed. Some elements were found to bioaccumulate in either the epidermis or cross-sections of water lilies, but majority showed equality of concentration in both sections.
