“…The average mCD merit for sampling spots SD1 (8.7743), SD2 (8.8194), SD3 (9.7614), and SD4 (9.7489) represented very high extent of pollution; however, SD5 (1.2799) showed evidently nil to very low extent of pollution (Table 4). Various unnatural factors, in combination with pedogenic variables, are solely accountable for greater mCD levels and spatial variability (Fahmida and Islam, 2018). The PLI is an instrument for evaluating the extent of metal toxicity that uses a set of comparing experimental indices (Manju et al, 2020).…”

The study was conducted to investigate the concentrations, distributions, sources and potential ecological risk of heavy metals in surface sediments from the Old Brahmaputra River. Sediment samples were collected from ve sampling stations and analyzed with inductively coupled plasma mass spectrometer (ICP-MS). The results showed that mean concentrations (mg/kg) of heavy metals were in order of Ni (58.82) Cr (32.45) Pb (21.04) Cu (14.24) Cd (3.81) As (2.02). In terms of spatial variation, sedimentary metals differed substantially, and the bulk of metal distribution and abundance can be traced back to man. Element-speci c environmental indices exposed that the ecological risks trailed the downward direction as Cd Ni Pb As Cu Cr. The contamination factor (CF), enrichment factor (EF) and geoaccumulation index (Igeo) exposed all cases a modest level of contamination except Cd, which has a signi cant level of contamination. Only, Ni and Cd were found high ecological risk for aquatic life, based on the sediment quality guidelines.Low to moderate ecological risk was suggested by the prospective ecological risk factor and potential ecological risk. The river sediments were mostly uncontaminated to mildly contaminated, posing a minimal ecological risk. The study concluded that the Old Brahmaputra River is subjected to anthropogenic disturbances for the aquatic environment. In this regards, proper management initiatives and regular monitoring should be carried out immediately by Department of Environment (DoE) to maintain sound and healthy aquatic environment of the River.

The study was conducted to investigate the concentrations, distributions, sources and potential ecological risk of heavy metals in surface sediments from the Old Brahmaputra River. Sediment samples were collected from five sampling stations and analyzed with inductively coupled plasma mass spectrometer (ICP-MS). The results showed that mean concentrations (mg/kg) of heavy metals were in order of Ni (58.82)˃ Cr (32.45)˃ Pb (21.04)˃ Cu (14.24)˃ Cd (3.81)˃ As (2.02). In terms of spatial variation, sedimentary metals differed substantially, and the bulk of metal distribution and abundance can be traced back to man. Element-specific environmental indices exposed that the ecological risks trailed the downward direction as Cd ˃ Ni ˃ Pb ˃ As ˃ Cu ˃ Cr. The contamination factor (CF), enrichment factor (EF) and geo-accumulation index (Igeo) exposed all cases a modest level of contamination except Cd, which has a significant level of contamination. Only, Ni and Cd were found high ecological risk for aquatic life, based on the sediment quality guidelines. Low to moderate ecological risk was suggested by the prospective ecological risk factor and potential ecological risk. The river sediments were mostly uncontaminated to mildly contaminated, posing a minimal ecological risk. The study concluded that the Old Brahmaputra River is subjected to anthropogenic disturbances for the aquatic environment. In this regards, proper management initiatives and regular monitoring should be carried out immediately by Department of Environment (DoE) to maintain sound and healthy aquatic environment of the River.
