Comparison of non-destructive techniques and conventionally used spectrometric techniques for determination of elements in plant samples (coniferous leaves)

Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and (ICP-MS) usually involve time-consuming sample preparation procedure a dissolution which requires the usage aggressive toxic chemicals. The need for suitable sustainable analytical methods direct multi-elemental analysis plant samples has been increased in recent years. Spectrometric analysis, instrumental neutron activation (INAA) X-ray fluorescence (XRF) have applied environmental studies various fields screening tests. Nevertheless, these are not commonly their performances to be evaluated. This research aimed assess how reliable non-destructive determination elements plants compared conventionally techniques. A total 49 four conifer species (Pinus nigra, Abies alba, Taxus baccata Larix decidua) were measured using two (ICP-MS, ICP-OES) (wavelength dispersive XRF (WD-XRF), INAA). comparison was performed by investigation relative ratios concentrations correlation analysis. Moreover, precision examined compared. quality control included NIST pine needles certified reference material (1575a) all Our results suggest that additional steps necessary reaching highest accuracy
