Terrestrial organic matter biomarkers as tracers of Hg sources in lake sediments [PDF]

open access: yes, 2010
Terrestrial organic matter (TOM) plays a key role in mercury (Hg) dynamics between watersheds and lakes. In this study we attempts to determine the role of TOM source and quality and not only quantity, in the fate and transport of total Hg (T-Hg) to ...

Modelling Sediment Transport and Sediment Quality in a Shallow Dutch Lake (Lake Ketel)

open access: yesWater Science and Technology, 1993
Lake Ketel is a shallow Dutch lake, part of the river Rhine delta, with a surface area of 38 km2. Between 1960 and 1980 15×106 m3 contaminated sediment accumulated in the lake. After 1980 the contaminant load started to decrease. A common hypothesis was that the relatively clean solids supplied now, would slowly cover the contaminated sediment layer ...

Natural and anthropogenic lead in sediments of the Rotorua lakes, New Zealand [PDF]

open access: yes, 2010
Global atmospheric sources of lead have increased more than 100-fold over the past century as a result of deforestation, coal combustion, ore smelting and leaded petroleum. Lead compounds generally accumulate in depositional areas across the globe where,

Kinetics of Radiocesium Sorption in Lake Sediments

open access: yesHealth Physics, 1994
The sorption of radiocesium (137Cs) in sediments sampled from Lake Pamvotis of Ioannina was studied in a laboratory simulation. In a series of experiments, the kinetics of 137Cs sorption and 137Cs distribution profiles in sediment cores were investigated.

Amplified bioproductivity during Transition IV (332 000–342 000 yr ago): evidence from the geochemical record of Lake El'gygytgyn [PDF]

open access: yes, 2013
To date, terrestrial archives of long-term climatic change within the Arctic have widely been restricted to ice cores from Greenland and, more recently, sediments from Lake El'gygytgyn in northeast Arctic Russia.

Year-round N2O production by benthic NOx reduction in a monomictic south-alpine lake [PDF]

open access: yes, 2013
Nitrous oxide (N2O) is a potent greenhouse gas, generated through microbial nitrogen (N) turnover processes, such as nitrification, nitrifier denitrification, and denitrification.

Prevalence, source and risk of antibiotic resistance genes in the sediments of Lake Tai (China) deciphered by metagenomic assembly: A comparison with other global lakes

open access: yesEnvironment International, 2019
Lakes are one of the natural reservoirs of antibiotic resistance genes (ARGs) in environments. Long retention times in lakes potentially allow ARGs to persist and may create increased opportunities for the emergence of resistant pathogens. In this study,
