Abstract :

The study was conducted to determine the pigmental composition of freshwater algae in Salog River, investigate the physicochemical properties of its water, and evaluate the quality of the river based on standard limits set by the national and international environmental agencies. Results of the pigmental analysis showed that chlorophyll a ranged from 1.226 to 28.238 ppm, chlorophyll b ranged from 3.526 to 21.180 ppm and total carotenoids from 2.274 to 7.994 ppm. The pigment composition of the freshwater algae showed a strong, positive correlation with the phosphorus, pH, TDS and conductivity levels of Salog River. On the contrary, only with TSS that the pigment composition of the algae showed a strong, negative correlation. On the other hand, the phosphorus (0.045-0.187 ppm), total dissolved solids (202.4-306.2 ppm) and total suspended solids (21.7-49.8 ppm) are below the tolerable limits set by DENR, WHO and USEPA. However, the pH (6.3-8.9) and conductivity (305.8-443.0 µS) values were within the standard limits. Thus, Salog River has a good water quality.
