Variations of tree ring width and chemical composition of wood of pine growing in the area nearby chemical factories

Abstract

This study reports the variation of tree-ring widths and annual variation of concentration of metals (Na, Mg, Fe, Ni, Cu, Zn, Pb) in pine growing nearby chemical factories. The conifers (Pinus silvestris L.) investigated in this study covered the time span from 1920s to 2010 AD. Tree-ring widths were measured, dated and rechecked using the COFECHA. Radial trace-element profiles were determined by Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The combined usage of tree ring width and chemical composition of wood provides historic records of anthropogenic impact on the environment and allows identifying the behavior adaptation of trees to the pollution. Data of pine tree cores collected from the sites nearby chemical factories show increasing levels of pollution linked to the increasing of industrial activities in Poland and subsequent dust fallout around the site. This study evidences that tree rings can be used as archives of past environmental contamination.

Determination of Metal Concentration in Road-Side Trees from an Industrial Area Using Laser Ablation Inductively Coupled Plasma Mass Spectrometry

“…This study showed that Pinus sp. (coniferous tree) reflected Pb and Cd concentrations in the atmosphere more effectively than the other elements measured, as confirmed by other studies [5,[28][29][30].…”

Variation of major elements and heavy metals occurrence in hybrid aspen (Populus tremuloides Michx. × P. tremula L.) tree rings in marginal land

“…Trees from temperate and boreal regions usually form visible annual growth rings that can be dated accurately. Hence, it is possible to collect wood samples of different ages to analyse the elemental composition of the tree rings (Nabais et al 1999, Sensula et al 2017. This method is known as dendrochemistry, i.e., the chronological analysis of elements in the annual growth rings of wood (Nabais et al 1999, Scharnweber et al 2016, Sensula et al 2017).…”

An important assumption in dendrochemistry is that the elemental concentrations in a given growth ring are the result of environmental conditions at the time of wood formation (Berger et al 2004, Vaganov et al 2013, Maillard et al 2016.…”

“…Many techniques have been used to analyse the matrix and trace elements including the toxic heavy metal content of tree rings, including XRF (x-ray fluorescence) spectrometry (MacDonald et al 2011, Smith et al 2014, Scharnweber et al 2016, XCT (x-ray computed tomography -Van Den Bulcke et al 2014), PIXE (particle-induced xray emission) analysis (Glass et al 1993, Calva-Vazquez et al 2006, EMPA (electron microprobe analyzer - Kuczumow 2004), XRD (x-ray diffraction), IR (infrared spectroscopy), SIMS (secondary ion mass spectrometry), and LA-ICP-MS, etc. (Watt et al 2007, Vašinová-Galiová et al 2013, Sensula et al 2017, Perone et al 2018. Of these techniques, LA-ICP-MS is becoming increasingly popular given its speed and ease of use.…”
