Geoenvironment and weathering of silicate minerals in sediments of the Brahmaputra river, India: Implications for heavy metal pollution assessment

Autor: Bhaskar J. Saikia, G. Parthasarathy, Rashmi R. Borah

Publikováno v: Geosystems and Geoenvironment, Vol 1, Iss 3, Pp 100065- (2022)

We carried out detailed compositional studies on fifteen sediment samples from the Brahmaputra River that were collected in the pre-monsoon period, to obtain the inherent contamination factor. The present study demonstrates that the degrees of metal
