The gills performs many functions in fish, such as respiration, osmoregulation and excretion. Galvanizing industry effluent induces hispathological changes in gills of Heteropneustes fossilis like lifting of respiratory epithelium, fusion of gill lamellae, multiple telangiecetasis and appearance of haemorrhagic areas. These indicate highly toxic na...

... Townsend and Doughlas (2017) reported that higher phytoplankton cell concentrations and biovolume during wet seasons in Daly river (first flood pulse) correspond to the high discharge and transportation of lentic phytoplankton originated from the external sources (floodplain water bodies) to the river main channel. The Cyanobacteria species were dominant in terms of numerical abundance across seasons in both the wetlands that significantly coupled with many other studies (Kumar & Oommen, 2011;Deka et al., 2009;Cardoso et al., 2017). Species mainly found were Dolichospermum, Lyngbya, Oscillatoria, Chroococcus, and Microcystis round the year indicating the sufficient amount of nutrients that supports for luxuriant growth of these algal groups. ...

... The present study, revealed that organic carbon and moisture content increased after flooding. A similar study on wetland soil has been conducted by Deka et al. (20) at Kapla Beel, a wetland in Barpeta district. Another study conducted by Singh et al. (21) in montane habitats at Nanda Devi Biosphere Reserve (NDBR), India during wet and dry seasons, which indicated that in dry season carbon cycle processes and nitrogen cycle processes were low as compared to wet season. ...
... This fact explains the lower removal capacity in a very acidic environment (pH < 2) since there is no electrostatic attraction between H CrO 2 4 and + NH 3 groups. According to different reports, most of the effluent from chromium industries is highly acidic and a highly effective adsorbent which is completely stable in low pH range would be a great advantage and industrially applicable [51,52]. ...

... Recent studies suggest that AChE is a very sensitive indicator of stress and hence can be useful for biomonitoring and assessment of the level of contamination (Richetti et al., 2011). In an era of industrialization, developing countries face a big problem in proper industrial waste treatment prior to its disposal due to technical limitations and heavy economic expenses behind the treatment process (Majumdar et al., 2007). Therefore, an effective management to prevent or at least minimize waste generation by developing technologies for waste recycling and reuse are the need of the hour (Jadhav and Hocheng, 2012). ...
