TLDR
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.
Abstract
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 earths surface environment? The environment of the earths surface is made of solids and fluids, and theinteractions among them are responsible for much of what is taking place in the physical world around us. The dissolved load of natural waters and the materials of which sediments are made are the products of reactions taking place practically everywhere on land, in the atmosphere, and in the hydrosphere. Thus the term water and sediment environments applies effectivelly to much of the surface environment of the earth, including the zone of up to a few kilometers above and below the land and ocean surface. Evolution present itself to us as a more or less complex variety of processes-geological, physical, chemical, and biological. To this end, the inclusive title Geochemical Processes was chosen for the book, to introduce a text that emphasizes processes and time-dependent phenomena.

Microbial reactions, chemical speciation, and multicomponent diffusion in porewaters of a eutrophic lake

TL;DR: In this paper, a mathematical model for the study of early diagenesis in lake sediments is presented, which includes microbial and geochemical reactions, inorganic chemical speciation of the dissolved components, and diffusion of the individual species between the boxes.

Distribution of mercury and methylmercury in deep-sea surficial sediments of the Mediterranean Sea

TL;DR: Rajar et al. as mentioned in this paper performed an investigation of the distribution, speciation and methylation of the mercury in deep-sea sediments of the Mediterranean Sea and found that MeHg production depends on partitioning of Hg(II) influenced by the organic carbon content in the sediment.

Hydrogen, carbon monoxide, and methane dynamics in Lake Constance

TL;DR: The vertical distributions of dissolved H, CO, and CH, and bacterial production (thymidine incorporation) were measured throughout 1987 in Lake Constance (Bodensee) and again in 1988 at a station in a small bight in the lake.

Sediment-associated contaminants — an overview of scientific bases for developing remedial options

TL;DR: In this paper, a review article covers three major aspects of scientific research on sedimentassociated contaminants during the last 20 years: identification and monitoring of sources and distribution (sampling; sample preparation; analyses, mainly of non-residual fractions; estimation of pollution potential); study of processes and mechanisms of pollutant transfer (interactions between dissolved and particulate element species; particle environments; transport and diagenesis: colloids; surface microlayers; particle related processes; bioturbation; dredging operations; remobilization of toxic elements; bioaccumulation of

Stoichiometry of carbon, hydrogen, nitrogen, sulfur and oxygen in the particulate matter of the western North Pacific marginal seas

TL;DR: In this article, the suspended particulate matter (SPM) in surface seawater was collected from 19 stations in the Sea of Japan, 42 stations in East China Sea, 7 stations North of Taiwan and 6 stations in Philippine Sea and the Bashi Channel.
