Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys

Archaeometry, Volume 68, Issue S4, Page S10-S38, July 2026.
Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire

Archaeometry, Volume 68, Issue S4, Page S86-S106, July 2026.
ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

Soil Lead Risks Associated With Urbanization Histories in Springfield MA and Hartford CT, USA

GeoHealth, Volume 10, Issue 6, June 2026.
Abstract Due to legacy leaded products, soil Pb is generally higher in older urban centers triggering substantial implications for environmental equity. By integrating a gridded soil Pb analysis of about 150 samples each in two historically industrial cities (Hartford, CT and Springfield, MA) with block‐level census data, we tested the hypotheses that (

Portable X‐Ray Fluorescence in the Assessment of Zinc Along Grizzly Bear Hair

X-Ray Spectrometry, Volume 55, Issue 3, Page 473-482, May/June 2026.
ABSTRACT As a biomarker of past uptake of zinc, hair presents an interesting option since its growth can provide a stored record over time. This study investigates the distribution of zinc in hairs gathered from a series of grizzly bears ( Ursus arctos horribilis ).
