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

Environmental Science and Pollution Research, 2023 Heavy metal(loid)s are widely regarded as important environmental pollutants and have attracted extensive attention. In addition to such areas with frequent human activities as cities and industrial areas, the heavy metal(loid) pollution in remote areas lacking long-term monitoring data also deserves attention.

Science of The Total Environment, 2020 The chemical analysis of tree rings has attracted the interest of researchers in the past five decades in view of the possibility of exploiting this biological indicator as a widely available, high-resolution environmental archive. Information regarding the surrounding environment can be derived either by directly measuring environmental variables ...

Science of The Total Environment, 2020 The potential of dendrochemistry as a tool for tracing anthropogenic contamination at a glassworks site in southeastern Sweden was investigated through a multidisciplinary approach combining continuous high-resolution time series of tree rings and sediment profiles. Tree cores from Scots pine (Pinus sylvestris), Norway spruce (Picea abies) and European

Biogeochemistry, 2014 Tree rings are a useful long term monitor of climate change indicators and certain atmospheric constituents. Since we have no long-term historical record of air mercury (Hg) concentrations, and previous research demonstrates atmospheric uptake of Hg into vegetative biomass, we hypothesized that tree rings would be a useful archive for monitoring ...

Dendrochemistry of White Mountain bristlecone pines: An investigation via Synchrotron Radiation Scanning X‐Ray Fluorescence Microscopy [PDF]
Journal of Geophysical Research: Biogeosciences, 2009 Synchrotron Radiation Scanning X‐Ray Fluorescence Microscopy (SXFM) was used for the first spatially/temporally resolved investigation of the multielemental chemistry of bristlecone pine (Pinus longaeva D.K. Bailey). A new protocol was designed to apply this nondestructive method of analysis to this unique palaeoclimatological resource, extracting ...

Environmental Science & Technology, 2011 As plants evolved to be extremely proficient in mass transfer with their surroundings and survive as earth's dominant biomass, they also accumulate and store some contaminants from surroundings, acting as passive samplers. Novel applications and analytical methods have been utilized to gain information about a wide range of contaminants in the ...
