- Abstract
Acid deposition occurred as the impact of air pollution due to the increased emissions of SO2 and NOx. If the acidic compounds fall into the inland aquatic (lake, river, or spring), it will disrupt the proliferation of organisms. Based on the previous study, low pH in inland aquatic generally affected the species diversity and plankton composition. This study aimed to figure out the impact of acid deposition in Situ Patengan - Bandung based on frequent monitoring. The study was undertaken in May, June, and September 2017 and March, June, October 2018 at 3 (three) sites, represented middle, inlet, and outlet of lake using survey method to conduct data collection. Plankton was identified using a microscope and calculated by the cell counting method. The results showed that the highest number of genera for phytoplankton in Situ Patengan was found in October 2017 whereas, the highest number of genera for zooplankton was found in May 2017. The range of diversity index (H’) was 0.13 – 1.45 for zooplankton and 0.61 – 1.73 for phytoplankton. The dominance index of zooplankton was 0.25 - 0.68 and phytoplankton was 0.14 – 0.40. The pH of Situ Patengan range from 7.5 to 8.6, while the average concentration of dominant ions were 6.7 mg/L of SO42- and 6.2 mg/L of Ca2+, respectively. Pearson correlation analysis of H+ and the abundance of both zooplankton and phytoplankton showed a very weak correlation. The pH range of 7.5 – 8.6 did not significantly affect the abundance of plankton. There were no obvious impact of acid deposition on inland aquatic had been detected in Situ Patengan during the investigated period.
