摘要：Acid deposition occurred as the impact of air pollution due to the increased emissions of SO 2and NOx. If the acidic compounds fall into the inland aquatic (lake, river, or spring), it willdisrupt the proliferation of organisms. Based on the previous study, low pH in inland aquaticgenerally aff ected the species diversity and plankton composition. This study aimed to fi gureout 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, October2018 at 3 (three) sites, represented middle, inlet, and outlet of lake using survey method toconduct data collection. Plankton was identifi ed using a microscope and calculated by the cellcounting method. The results showed that the highest number of genera for phytoplanktonin Situ Patengan was found in October 2017 whereas, the highest number of genera forzooplankton was found in May 2017. The range of diversity index (H’) was 0.13 – 1.45for zooplankton and 0.61 – 1.73 for phytoplankton. The dominance index of zooplanktonwas 0.25 - 0.68 and phytoplankton was 0.14 – 0.40. The pH of Situ Patengan range from7.5 to 8.6, while the average concentration of dominant ions were 6.7 mg/L of SO 4 2- and 6.2mg/L of Ca 2+ , respectively. Pearson correlation analysis of H + and the abundance of bothzooplankton and phytoplankton showed a very weak correlation. The pH range of 7.5 – 8.6did not signifi cantly aff ect the abundance of plankton. There were no obvious impact of aciddeposition on inland aquatic had been detected in Situ Patengan during the investigated period.
