    Bio-monitoring - a tool for assessment of biotic and abiotic parameters in two major Riverine ecosystem
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Sumit Kumar; Saxena, Amita
    Biomonitoring of two major riverine ecosystem Ganga and Yamuna was carried out to know the present situation of rivers. In Ganga river three sites from each district viz: Haridwar (A1), Bijnor (A2) and Muzaffarnagar (A3) and One site from Union territory Delhi (B1) and two sites from districts of U.P. viz: Mathura (B2) and Agra (B3) were selected from Yamuna river.In Ganga river a total of 39 fish species belonging to 8 orders and 16 families were recorded whereas in Yamuna river a total of 45 fish species belonging to 8 orders and 16 family were recorded. The Physico-chemical parameter of Ganga river was found better than Yamuna river. The occurrence of heavy metals in fishes of Ganga river were in order Pb > Zn > Cu > Cr > Hg > Cd. The level of Pb was found above the recommended level of WHO in fishes.The occurrence of heavy metals in Yamuna river were found in the order Zn> Cr > Pb > Cu > Cd > Hg. The level of Pb, Cd, Hg & Cr were found above the recommended level of WHO in fishes. In Ganga river water heavy metals were found in the order: Pb> Cu> Zn> Cr> Cd> Hg while in Yamuna river found in the order: Cr> Zn> Pb> Cu> Cd> Hg. Pb in Ganga &Pb, Cd, Cu, Cr & Zn in Yamuna water was found above the recommended level of WHO. The accumulation of heavy metals in Eichhornia crassipesof Ganga and Yamuna river was found in the order: Zn >Cr >Pb > Cu >Cd >Hg and Zn >Pb >Cr > Cu >Cd >Hg respectively. The level of heavy metals in sedimentof Ganga and Yamuna river was found in the order: Zn >Cr >Pb >Cu >Cd >Hg and Cr >Zn >Pb >Cu > Cd >Hg. In macro-benthic community of Ganga river were found in the order:Cr>Zn>Cu>Pb>Cd>Hg while in Yamuna Zn>Cr>Pb>Cu>Hg>Cd. Planktonic density was greater in Yamuna river. Suitable bio-indicators from both the rivers were also documented.
