Contamination of potentially toxic metals (PTMs) can be detrimental to ecological processes, diversity and physiology of biological components of the surrounding habitat of estuarine and coastal environment. In our study, an inclusive approach to measure ecotoxicological parameters was followed considering spatial concentration of PTMs in the sediment system, sediment quality status, ecological risk level, bioconcentration in mangrove tissue and resulting biochemical and antioxidative response in mangroves

Present study revolves around the assessment of basic physicochemical parameters, dissolved PTEs, and microplastics (MPs) in riverine water to illuminate the policies for better sustainable management practices in river Hooghly. The samples were analysed in ICP-OES and fluorescence microscope to enumerate PTEs and MPs. The distribution of PTEs indicates that highest concentration of Al, Co, and Cu was in estuarine zone; Cd, Cr, Fe, Mn, Ni, and Pb in mixo-haline zone and Zn in freshwater zone. The maximum concentration of MPs was observed near Bali Khal, which acts as a sewage canal of the urban conglomerate of Howrah. Overall, the size of MPs was observed between 150 and 4560 lm with an abundance frequency of 1000 pieces/m$^3$ near the mouth of the sewers. Dissolved PTEs concentration was found to be lower than previous works, which can be attributed towards GoI approved Cagship program ‘Namami Gange Mission’. The study emphasizes the necessity of a uniform national water policy for better management of Indian rivers and estuaries.
