Spatiotemporal Distribution of Mercury in Tree Rings and Soils Within Forests Surrounding Coal-Fired Power Plants

open access: yesAtmosphere
The release of mercury (Hg) from coal-fired power plants (CPPs) into local ecosystems poses substantial environmental and health hazards. This study was conducted in Chungcheong-nam-do, South Korea, a region featuring over half of the country’s coal ...

Synchrotron dendrochemistry: Exploring the comparison of multi-dimensional elemental analysis methodologies on tree cores using synchrotron techniques [PDF]

open access: yes, 2020
The research conducted in this thesis assesses the feasibility of using X-ray fluorescence (XRF) spectroscopy to determine concentrations (i.e., ppm and ppb) of heavy metals in tree core samples.

Methodology for Development of a 600-Year Tree-Ring Multi-Element Record for Larch from the Taymir Peninsula, Russia [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2013
We developed a long (600-year) dataset for the concentrations of 26 elements in tree rings of larch from the Taymir Peninsula, the northernmost region in the world (ca. 72°N) where trees grow. Tree rings corresponding to the time period from 1300 to 1900

Tropical dendrochemistry: A novel approach to estimate age and growth from ringless trees

open access: yesGeophysical Research Letters, 2006
Although tropical forests play an active role in the global carbon cycle and climate, their growth history remains poorly characterized compared to other ecosystems on the planet. Trees are prime candidates for the extraction of paleoclimate archives as they can be probed sub‐annually, are widely distributed and can live for over 1400 years [Chambers ...

Some considerations in the reconstruction of lead levels using laser ablation: lessons from the design stage of dendrochemistry study, St.John's, Canada

open access: yesGeochronometria, 2015
Study of soils in St. John’s, Canada showed elevated Pb levels representing a potential ex-posure risk for young children. Old trees growing in the city present a potential annually-resolved record of Pb levels over past centuries that provides important temporal and spatial dimensions to Pb exposure risk assessment.
