Mercury in lake sediments: a possible indicator of technological growth.
TLDR
The authors' sediments are from an English lake in a predominantly rural area and it seemed to us that lake sediments, which geologically have a relatively rapid rate of deposition, might produce further evidence of man's input of Hg to the environment.Abstract:
GOLDBERG1 has estimated that at present man is responsible for about half of the total Hg released into the environment, and pollutant Hg has already been found in snow and ice2 and near-shore marine sediments3. It seemed to us that lake sediments, which geologically have a relatively rapid rate of deposition, might produce further evidence of man's input of Hg to the environment. This has been shown to occur in sediments from a Canadian lake which receives industrial waste4. Our sediments are from an English lake in a predominantly rural area.read more

TL;DR: This significant book provides not only an introduction to the dynamics of aquatic chem istries but also identifies those materials that jeopardize the resources of both the marine and fluvial domains.

The calculation of lead-210 dates assuming a constant rate of supply of unsupported 210Pb to the sediment
Peter G. Appleby,Frank Oldfield +1 more
TL;DR: In this paper, a method of calculating sediment age from 210Pb profiles where changes in accumulation rate have affected initial 210pb concentration is described. But the assumption of a constant initial concentration of unsupported 210PB per unit dry weight at each stage of accumulation, despite variations in accumulation rates, is incorrect.

Inorganic Geochemical Methods in Palaeolimnology
TL;DR: In this article, a distinction is made between inorganic geochemical palaeolimnology and organic geochemistry in general, and a distinction between organic and inorganic methods is made.

Modeling the Past Atmospheric Deposition of Mercury Using Natural Archives
TL;DR: It is suggested that smearing of 210Pb in the uppermost peat sections contributes to an underestimation of peat ages, which is the most important reason for the overestimation of mercury accumulation rates in many bogs.

A primer on trace metal-sediment chemistry
TL;DR: In this paper, the authors present a broad overview of the physical and chemical factors that govern the concentration and distribution of trace metals associated with bottom and suspended sediments, including grain size, surface area, surface charge, cation exchange capacity, composition and so forth.

A short core sampler for subaqueous deposits
TL;DR: In this paper, an instrument was designed to obtain a core 1 m long and 5 cm diam, and to include a few centimeters of water above the sediment surface so that the position of the sediment-water interface can be determined with accuracy.

Mercury in a Greenland Ice Sheet: Evidence of Recent Input by Man
TL;DR: The increased mercury content in a Greenland ice sheet over the last several decades suggests the dissemination of this element about the earth's atmosphere through the activities of man.

The Distribution of Mercury in the Sediments of Lake Ontario
TL;DR: The average concentration of mercury in the nearshore sediments is 355 ppb, in the basin sediments 997µppb and the average for the whole lake is 651µ ppb as mentioned in this paper.
