Contamination and ecological risk assessment of trace elements in sediments of the rivers of Sundarban mangrove forest, Bangladesh.
M. A. Islam,Abdullah Al-Mamun,Faisal Hossain,Shamshad B. Quraishi,Kamrun Naher,Rahat Khan,Sopan Das,Umma Tamim,Syed Mohammod Hossain,F. Nahid +9 more
TL;DR: Trace element contamination assessment, using different environmental contamination indices, reveals that As, Sb, Th and U are low to moderately contaminated while Cd is moderately to severely contaminated in the sediments of this area.
Journal ArticleDOI
Elemental distribution of metals in urban river sediments near an industrial effluent source.
Umma Tamim,Rahat Khan,Y. N. Jolly,K. Fatema,Sopan Das,Kamrun Naher,M. A. Islam,S.M. Azharul Islam,Syed Mohammod Hossain +8 more
TL;DR: Major elements are somehow buffered even though the pollution level is severe while the trace metals seem to be highly responsive, and the sediments of this study respond differently depending upon their geochemical behavior.
Journal ArticleDOI
Distribution, sources and ecological risk of trace elements and polycyclic aromatic hydrocarbons in sediments from a polluted urban river in central Bangladesh

TL;DR: In this paper, the spatial and layer-wise distributions of 26 elements (Na, Al, Mg, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Sb, Co, Ba, Zn, Rb, Cs, La, Ce, Sm, Eu, Yb, Ta, Hf, Th and U) as well as the spatial distributions of polycyclic aromatic hydrocarbons (PAHs) in a polluted urban river (Turag, Bangladesh).
Journal ArticleDOI

TL;DR: In this paper, nuclear analytical techniques such as instrumental neutron activation analysis, energy dispersive X-ray fluorescence, gamma spectrometry are used for soil sample study whereas atomic absorption spectroscopy, UV-vis spectrophotometer etc. were used for water sample analysis.
Journal ArticleDOI
Spatial and multi-layered assessment of heavy metals in the sand of Cox’s-Bazar beach of Bangladesh
Rahat Khan,Mohammad Abdur Rouf,Mohammad Abdur Rouf,Sopan Das,Umma Tamim,Kamrun Naher,Jiban Podder,Syed Mohammod Hossain +7 more
TL;DR: In this article, the elemental abundances of beach sands collected from Cox's Bazar, Bangladesh for the purpose of understanding the spatial and layer-wise distribution of heavy elements and their provenance were presented.
