Early-Wood vs. Late-Wood in Scots Pine: Finding Stable Relationships in Elemental Distribution
Sci, 2023 This study explored whether consistent differences can be found between early-wood and late-wood in terms of elemental content of tree rings. The species to study was Pinus sylvestris L. growing within an even-aged stand planted during the early 1970s in

Dendrochemistry in Public Health: A Case Study in North Carolina, USA
Forests, 2022 Dendrochemistry, the measurement of element concentrations in tree rings for the purpose of assessing temporal changes in chemical environments, was used to study an area in south-central North Carolina, USA, that has experienced higher than expected incidences of a couple human illnesses.

Diversity, 2023 In dendrochemical studies, an analysis of wooden cores extracted from tree stems is a widely spread research method. A methodological problem is related to the method: whether a single core per tree can be representative of all the stems. The study aimed

Reconstructing Soil Recovery from Acid Rain in Beech (<i>Fagus sylvatica</i>) Stands of the Vienna Woods as Indicated by Removal of Stemflow and Dendrochemistry. [PDF]
Water Air Soil Pollut, 2019 Our goal was to reconstruct soil recovery from Acid Rain based upon removal of stemflow at beech (Fagus sylvatica) stands of known historic and recent soil status. Fourteen beech stands in the Vienna Woods were selected in 1984 and again in 2012 to study changes in soil and foliar chemistry over time.

Dendroclimatology in Latin America: A Review of the State of the Art
Atmosphere, 2022 The application of dendrochronology for understanding climatic variations has been of great interest to climatologists, ecologists, geographers, archeologists, among other sciences, particularly in recent decades when more dendrochronological studies ...

Dendrochemistry of Multiple Releases of Chlorinated Solvents at a Former Industrial Site [PDF]
Environmental Science & Technology, 2012 Trees can take up and assimilate contaminants from the soil, subsurface, and groundwater. Contaminants in the transpiration stream can become bound or incorporated into the annual rings formed in trees of the temperate zones. The chemical analysis of precisely dated tree rings, called dendrochemistry, can be used to interpret past plant interactions ...

Laser Trimming Tree-Ring Cores for Dendrochemistry of Metals [PDF]
Tree-Ring Research, 2005 This article discusses the application of laser to trim the outer surface from tree-ring increment cores in preparation for dendrochemistry of certain metals. A source of contamination specific to dendrochemistry of metals is metal constituents, such as iron, tungsten, chromium, nickel, and cobalt, coming off tools used to collect and process cores and
