AbstractRecently, element concentrations in tree rings have been used to monitor metal contamination, fertilization, and the effects of acid precipitation on soils. This has stimulated interest in which tree species may be suitable for use in studies of long‐term trends in environmental chemistry.

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.

Early- and Latewood vs. Stem Asymmetry: Which Is More Important for Dendrochemistry in Scots Pine?
ForestsFor dendrochemical research, it may be important to be aware of the effects of stem asymmetry and the intra-ring structure because these may introduce unwanted dispersion in the results. In dendrochemical studies, separate analysis of the elemental content of early- and latewood is rare.

Dendrochronological methods have been in use for more than 100 years, providing us a record of climate, human activities (archaeology), floods, fire, mudslides and other geological and biological events. More recently, dendrochemisty has been used to assess the time frames of the onset and existence of environmental contamination. This article assesses

Change in the dendrochemistry of sacred fir close to Mexico City over the past 100 years
Environmental Pollution, 1999The chemistry of the tree-rings of sacred fir (Abies religiosa) growing in the high elevation forest park, Desierto de los Leones, close to Mexico City was measured in 5 year increments dating back to 1897. Surface soil beneath sampled trees had elevated concentrations of trace metals, especially Pb, Cd and Zn, compared with a reference site at San ...

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 ...

Dendrochronologia, 2010
Abstract The maple-dominated forest of eastern Canada and northeastern United States has experienced forest decline that can be linked to changes in soil fertility and soil acidification. In this study, we used a new dendrochemical approach to trace back changes in nutrients (Ca, K, Mg, and Mn) and Al availability.

Plant and Soil, 2004
Ten pairs of secondary pure spruce (Picea abies) and adjacent mixed spruce-beech (Fagus sylvatica) stands on comparable sites were selected on two different bedrocks for soil formation (Flysch: nutrient rich and high soil pH; Molasse: poor nutrient supply and acidic) to study how an admixture of beech to spruce stands affects nutrient cycling and ...

Drilling at the c. 750 m deep Halliday Lake prospect in the Athabasca Basin has identified features favourable for unconformity-related U mineralization such as sandstone enrichments in pathfinder elements, graphitic metapelite gneiss, sandstone and basement hosted faulting, hydrothermal alteration and sub-economic ...
