“…With the passages of time, tremendous human pressure on Buriganga river in terms of playing motorized water vessels, infrastructural development, encroachment, industrial and sewage waste dumping, etc. and dumping of ever-increasing all sorts of wastes turned Buriganga a worst polluted and ecologically dysfunctional river (Hossain, A. M. M., & Rahman, S., 2011;Parvin, S et al, 2017). The Buriganga receives especially high amounts of food waste including rotting fruits, vegetables, and most alarming plastic can/container, poly bags are thrown into the river (DoE, 2014).…”

Bangladesh is situated in the lower part of the Ganges-Brahmaputra-Meghna (GBM) river basin, which is one of the most populated countries in the world. The Buriganga river system is located in the southern part of the northcentral region of the country, which passing through west and south of Dhaka, the capital of Bangladesh. A total of 96 water samples were collected from eight different points along the river and considered 10 physiochemical parameters such as Temperature, pH,

In tannery, fleshing is the unavoidable solid waste which has negative effect on the environment. Fleshing contains fat, and protein.In this work, fat extracted fleshing was used for composite fabrication. After collecting limed fleshing, fat was extracted in water bath.The fat extracted fleshing was dried, ground,passes through 80-mesh and homogenized.For proper adhesion and bonding with fleshing powder, epoxy resin and hardener were mixed at various ratios and poured onto an aluminum sheetfor 24 h curing. The mechanical properties of the composite were investigated by tensile strength, elongation at break, and Young’s modulus. The composite was characterized by Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscope (SEM) for related functional groups and surface analysis. The investigation provided satisfactory information on the proper bonding of the fleshing powder and resin/hardener. The approach explores the valorization of he waste for managing solid waste in the tannery. Bangladesh J. Sci. Ind. Res.56(3), 215-222, 2021

“…Large numbers of tanneries clustered in the Jajmau area of Kanpur city ( Fig. 1) discharge their effluents into the river Ganga after inadequate treatment and containing several toxic metals and organic substances [9,[14][15][16][17][18]. These toxins affect the aquatic organisms of almost all tropic levels [19].…”

Long-term phytoremediating abilities of Dalbergia sissoo Roxb. (Fabaceae)

The boom of tanneries in north India has converted the river Ganga into a waste dumping stream. The tanneries discharge their heavy metal-rich effluents into the river. Tissues of two-year-old tree saplings of Dalbergia sissoo, soil sediments and river water samples were collected from three sites along the river Ganga at Jajmau, Kanpur. Site-1 was located 1 km upstream from the point of discharge of the effluents of the tanneries, Site-2 was close to the source point, and Site-3 was about 1 km downstream from the source point. Accumulation of Cu, Cr and Ni in leaves, bark, wood growth rings, soil sediments and water samples was estimated using an atomic absorption spectrophotometer. The tissues of the two-year-old wood growth rings of D. sissoo accumulated large amounts of Cr, Cu and Ni. The Cr concentration in leaves, bark and wood rings had a strong, positive and linear correlation (r 2 ) with the Cr concentration in soil sediments. The bioconcentration factors (BCFs) of Cr, Cu and Ni were higher than 1 in the wood, bark and leaves at all three selected sites, indicating the strong phytoremediating ability of the tree. The uptake of Cr and Ni was consistent in the bark and wood growth rings of two successive years. Owing to the strong uptake and accumulating abilities of Cr, Cu and Ni as evident from high BCF values and high biomass, we propose D. sissoo as a suitable species for phytoremediation throughout its range of distribution in Africa, Asia and the Americas.
