Modelling the kinetic reactive transport of pollutants at the sediment-water interface. Applications with atmospheric fallout radionuclides

J. M. Abril et al.

Summary: This study investigates the behavior of particulate matter and chemicals at the sediment-water interface using a kinetic reactive transport model. It identifies a series of factors governing the fate of tracers in this region, leading to a diverse range of behaviors. Eddy diffusivity in the pore fluid can explain observed penetration depths for certain elements, while others are retained in thinner sediment layers.

Fine-tuning of 210Pb-based methods for dating vegetated saltmarsh sediments

A. R. Iurian et al.

Summary: This paper reviews and adapts existing methods for Pb-210-based radiometric dating of saltmarsh sediments, considering sources of achronicity from underground production and decay of organic matter, and discusses the effects of these sources on the use of models. The impact of non-ideal boundary conditions in radiometric dating and the system time-average of Cs-137 fluxes are illustrated with new data from two sediment cores, providing generic applications for other vegetated coastal sediments.

Sediment profile dating and reconstructing nuclear events from annually laminated lake sediments in northern Finland

Eeva Haltia et al.

Summary: The study of sediments from Lake Kevoja in northern Finland revealed detailed records of past nuclear events, including atmospheric nuclear weapons testing in the 1950s and 1960s and the Chernobyl accident in 1986. Measurements showed significant variations in 137Cs and 241Am concentrations between different sediment layers marking different historical nuclear events. Long-term observations of 210Pb concentrations indicated variations due to sediment input, with the Constant Rate of Supply (CRS) model showing no effect of climate change on 210Pb deposition over the last 80 years.
