Chemical composition of suspended sediments in World Rivers: New insights from a new database
TLDR
A new database on the chemical composition of suspended matter in World Rivers, together with the associated elemental fluxes is presented, showing that riverine fluxes are similar to anthropogenic fluxes, which casts light on the effect of human activities on the cycles of trace elements at the Earth's surface.About:

Global Synthesis and Critical Evaluation of Pharmaceutical Data Sets Collected from River Systems
TL;DR: A global-scale analysis of the presence of 203 pharmaceuticals across 41 countries is presented and it is shown that contamination is extensive due to widespread consumption and subsequent disposal to rivers.

Mineralogical and chemical variability of fluvial sediments 2. Suspended-load silt (Ganga–Brahmaputra, Bangladesh)
Eduardo Garzanti,Sergio Andò,Christian France-Lanord,Paolo Censi,Pietro Vignola,Valier Galy,Maarten Lupker +6 more
TL;DR: In this article, the authors combined Raman spectroscopy with traditional heavy-mineral and X-ray diffraction analyses, carried out separately on low-density and dense fractions of all significant size classes in each sample.

Grain size control of river suspended sediment geochemistry: Clues from Amazon River depth profiles
Julien Bouchez,Jérôme Gaillardet,Christian France-Lanord,Laurence Maurice,Poliana Dutra-Maia +4 more
TL;DR: In this article, the chemical and isotopic variability of river sediments of the Amazon Basin, collected at different water depths, as a function of grain size, was characterized and a double normalization diagram was proposed to correct from dilution effects.

Sediments in urban river basins: a review of sediment–contaminant dynamics in an environmental system conditioned by human activities
Kevin G. Taylor,Philip N. Owens +1 more
TL;DR: In this paper, the authors provide a state-of-the-art assessment of sediment sources, pathways and storage within urban river systems, to consider sediment management within urban systems and river basins, and examine the role of local and global environmental changes on sediment processes and management.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Quantitative assessment of worldwide contamination of air, water and soils by trace metals
Jerome O. Nriagu,Jozef M. Pacyna +1 more
TL;DR: Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements.

World-Wide Delivery of River Sediment to the Oceans
John D. Milliman,Robert H. Meade +1 more
TL;DR: The authors showed that rivers with large sediment loads (annual discharges greater than about $15 \times 10^{6}$ tons) contribute about $7 −times 10 −9$ tons of suspended sediment to the ocean yearly.
Impact of Humans on the Flux of Terrestrial Sediment to the Global Coastal Ocean
TL;DR: Global estimates of the seasonal flux of sediment, on a river-by-river basis, under modern and prehuman conditions are provided, showing African and Asian rivers carry a greatly reduced sediment load; Indonesian rivers deliver much more sediment to coastal areas.

TL;DR: In this article, the seasonal flux of sediment, on a river-by-river basis, under modern and prehuman conditions, is provided, and the authors show that humans have simultaneously increased the sediment transport by global rivers through soil erosion (by 2.3 ± 0.6 billion metric tons per year), yet reduced the flux reaching the world's coasts (by 1.4 ± 0 3 billion metric ton per year) because of retention within reservoirs.
