The present study has been conducted to assess the surface water quality of Halda River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.93-5.15 mg/L, 30-545 mg/L, 43-983 mg/L, 6.3-7.3, 110-524 uS/cm, 12-56 mg/L, 35-67 mg/L, and 38-121 mg/L, respectively. Multivariate statistical analys...

The Halda River and Haor basins are considered unique breeding habitats for carps in Bangladesh. purpose of the study was to evaluate natural spawning environment carp species, with an emphasis on hydrological conditions River, Surma Tanguar Haor. This study, which covers years 2021 2022, two seasons. results revealed that temperature, total dissolved solids (TDS), salinity, turbidity, conducti...

In recent decades, water quality is a great concern for the human being as it most important natural resource but polluted by increasing population activities. this study, surface samples were collected in wet and dry season from Halda River, Bangladesh, 12 physicochemical properties 10 traces elements (Cd, Cr, Mn, Fe, Co, Cu, Zn, As, Pb, Hg) analyzed to assess metal toxicity, identify possible...

Indexical appraisal of potentially toxic elements (PTEs) in sediment and fish riverine ecosystem give valuable information for environmental management. In this research, PTEs were measured soft tissues six species from an important breeding river (Halda) Bangladesh to assess quality human health risks. The abundance sediments varied the decreasing order Fe > K Ca Ti Zr Sr Rb Mn Zn Cu Ni Pb Co....
