摘要

This study, conducted during 2022–23, evaluates the ecological status of the Mirusha River using macrophytes as bioindicators. Industrial pollution, sewage, agricultural runoff, and climate change significantly affect river ecosystems, leading to degradation of water quality and biodiversity. The Mirusha River, heavily polluted by untreated sewage, solid waste, and agricultural runoff, was examined through macrophyte sampling and analysis of physicochemical parameters at six locations. The research used standard methodologies to assess macrophyte diversity and abundance, identifying 53 species across 25 families. The average values indicate severe water pollution, with a high biochemical oxygen demand (BOD) of 24.3 mg/L and a chemical oxygen demand (COD) of 38.4 mg/L, indicating a high organic load. In addition, the average nutrient concentrations were very high including Nitrites (NO2−) reaching a value of 0.95 mg/L, Total nitrogen (NT) 16.4 mg/L, Ammonia (NH4+) 2.42 mg/L, Total phosphorus (PT) 0.72 mg/L and Nitrates (NO3−) 7.1 mg/L. The study identified distinct pollution impacts: the upper areas (SP1–SP3) were the most polluted due to industrial and residential waste, while the lower regions (SP4–SP6) faced pollution from gastronomy and infrastructure. The findings suggest that anthropogenic activities and poor water quality significantly affect macrophyte communities, highlighting the need for targeted restoration efforts to improve river health and biodiversity.
