TL;DR: In this article, a study was conducted to measure globally alarming of ten heavy metals (Pb, Cd, Cr, Cu, Hg, Al, Ni, Co, Zn and Mn) in surface water and sediment of the Old Brahmaputra River in Bangladesh.

TL;DR: In this paper, the authors assess the status of heavy metal contamination and health risks associated with the use of water from River Gomti by millions of people and suggest that immediate remedial measures are required to control the elevated levels of heavy metals at all the sampling stations.

TL;DR: Inverse geochemical modeling of PHREEQC code suggests that carbonate dissolution and ion exchange of major ions are the prevailing geochemical processes at the deltaic region of the Nakdong River Basin in the Busan Metropolitan City of Korea.

TL;DR: Correlation of geochemical parameters reveals a excellent positive correlation between Ca and NO 3 in SUM, SWM, and NEM due to the dominant of anthropogenic sources and minor influence of weathering process and principal component analysis of different seasons indicates the interplay of natural weathering and anthropogenic factors.

TL;DR: In this paper, the contamination level of seven heavy metals (Pb, Cd, Cr, Ni, Zn, As, and Cu) along with their potential ecological risks in sediments from the Halda river which is the largest natural carp breeding ground in South Asia.
