Fifty-year sedimentary record of heavy metal pollution (Cd, Zn, Cu, Pb) in the Lot River reservoirs (France).
TL;DR: 137Cs activities and heavy metal concentration-depth profiles from sediment cores retrieved in 2001 from three reservoirs in the Lot River allow establishing a connection between the temporal evolution of the heavy metal pollution and historical changes in smelting and waste-treatment proceedings.

Zn isotopes as tracers of anthropogenic pollution from Zn-ore smelters The Riou Mort–Lot River system
Yann Sivry,Jean Riotte,Jeroen E. Sonke,Stéphane Audry,Jörg Schäfer,Jérôme Viers,Gérard Blanc,Rémi Freydier,Bernard Dupré +8 more
TL;DR: In this article, the extraction yields for these samples were calculated using presumable conservative elements (Fe, Ca, Mg, K, Na and Mn) and vary from 95.4% to 99.4%.

Effective rhizoinoculation and biofilm formation by arsenic immobilizing halophilic plant growth promoting bacteria (PGPB) isolated from mangrove rhizosphere: A step towards arsenic rhizoremediation.

TL;DR: Two As-resistant halophilic bacterial strains were isolated, identified and characterized from mangrove rhizosphere of Sundarban and when used as inoculum promoted the growth of rice seedlings but also decreased As uptake and accumulation in plants.

Assessing the current state of the Gironde Estuary by mapping priority contaminant distribution and risk potential in surface sediment
TL;DR: In this article, the first spatial distribution maps for the eight trace elements identified as priority contaminants in aquatic systems (i.e., Cd, Cr, Cu, Hg, Ni, Pb and Zn) in surface sediments of the Gironde Estuary (SW France) are presented.
Journal ArticleDOI
Geochemical survey and metal bioaccumulation of three bivalve species (Crassostrea gigas, Cerastoderma edule and Ruditapes philippinarum) in the Nord Medoc salt marshes (Gironde estuary, France)
TL;DR: Results suggest trace metal recycling due to reductive dissolution under suboxic conditions at the sediment surface resulting in trace metal release to the water column and adsorption onto suspended particles.

Early Diagenesis: A Theoretical Approach
TL;DR: In this article, Berner developed the mathematical theory of early diagenesis, introducing a general diagenetic equation and discussing it in terms of each major diagenetics process, including diffusion, compaction, pore-water flow, burial advection, bioturbation, adsorption, radioactive decay and especially chemical and biochemical reactions.

Diffusion of ions in sea water and in deep-sea sediments
Li Yuan-Hui,Sandra Gregory +1 more
TL;DR: The tracer diffusion coefficients of ions in deep-sea sediments, Dj,sed., can be related to Dj∗ by as mentioned in this paper, where θ is the tortuosity of the bulk sediment and a constant close to one.

Manual for the geochemical analyses of marine sediments and suspended particulate matter
D.H. Loring,R.T.T. Rantala +1 more
TL;DR: A detailed description of the techniques and analytical procedures for sampling, grain size determinations, and for precise and accurate AAS determination of the major and trace metals in marine sediments and suspended particulate matter is given in this paper.

Geochemical Processes: Water and Sediment Environments
TL;DR: The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earth's surface environment? The environment of the earths surface is made of solids and fluids, and the interactions among them are responsible for much of what is taking place in the physical world around us as mentioned in this paper.

Transport phases of transition metals in the Amazon and Yukon Rivers
TL;DR: In this article, samples representing yearly averages of material transported by the Amazon and Yukon Rivers were analyzed to separate the transition metals (Cr, Mn, Fe, Co, Ni, and Cu) into the following transport phases: (1) crystalline particles, (2) metal hydroxide coatings, (3) solid organic material, (4) sorbed material, and (5) those in solution.
