Geochronological implications of 210Pb and 137Cs mobility in cave guano deposits

International Journal of Speleology, 2021
Some recent publications on the paleo- and historical environmental interpretation of bat guano sequences have relied on 210Pb and 137Cs distribution to establish age-depth models, even when these are at odds with radiocarbon models in the lower parts of

Radioactivity and measurements of sediment deposition rate of the Drenova reservoir (B&H) [PDF]

Nuclear Technology and Radiation Protection, 2012
This work presents the first estimate of the radioactivity and sediment deposition rate of the Drenova reservoir. The radioactivity and sedimentation rate were computed applying the 210Pb and 137Cs methods.

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

Water and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Measurement of 210Pb and its application to evaluate contamination in an area affected by NORM releases

, 2008
Liquid scintillation counting (LSC) is an easy and straightforward technique, and combined with its low limit of detection, makes it a powerful tool for both routine and low level measurements that can be applied to 210Pb low level counting in ...

Inundation and Sediment Supply Predict Annual but Not Centennial Carbon Accumulation in Tidal Wetlands Across Land‐Use Types

Global Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Despite growing interest in the contributions of tidal wetlands to natural climate solutions, data remain scarce on how land use affects their carbon accumulation rates (CAR). Additionally, environmental factors driving the large observed variability in CAR among sites are poorly understood.
