The main purpose of this investigation is to evaluate the concentrations of six essential metals (Na + , Mg 2+ , K + , Ca 2+ , Fe 2+ and Zn 2+ ) in saffron and a farm soil using the neutron activation analysis (NAA) as a nuclear spectrometry method. The stratified random sampling method was used here. The NAA results showed the well uptake of Mg 2+ , K + , Ca 2+ , Fe 2+ , and Zn 2+ in saffron, which is lower than the toxicity range. Based on the contamination factor and geoaccumulation index, soil contamination levels were determined uncontaminated by Zn, moderately contaminated by Na + and Fe 2+ , and strongly contaminated by Ca 2+ , K + , and Mg 2+ . Results of the contamination degree and pollution load index indicated moderately/strongly soil contamination and a moderate geometric mean of the contamination index. The Na + enrichment factor (EF) showed a minimal man-made impact on sodium enrichment. Saffron cultivation has likely caused more accumulations of Mg 2+ , K + , Ca 2+ , and Fe 2+ , as well as a considerable deficiency of Zn 2+ in the soil, based on EFs. The biological concentration factor showed a significant zinc accumulation by the corm of saffron. There was well translocation from corm to all the aerial tissues for K + . Also, sodium adsorption ratio, exchangeable sodium percentage, pH, and electrical conductivity evaluated the non-salinity level of soil in all saffron farms.

“…As is evident, four methods occupy a predominant position in the certification, namely, inductive coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS), neutron activation (Dybczyński et al 2003) and deserves a profound reflection. As follows from a recent review encompassing the time span of 40 years, in the years 1975-1980, the NAA was a dominating technique and its share was in the range of 40-66% (Dybczyński 2019). AAS occupied the second place followed by X-ray fluorescence (XRF), and ES.…”

“…We are living in an era when many important decisions (administrative, forensic, technological, ecological, biomedical, etc.) may depend upon the results of chemical analysis including also trace analysis (Dybczyński and Polkowska-Motrenko 2015;Dybczyński 2019). It is obvious that the correct decisions can be taken only when the analytical results on which they are based are reliable.…”

Three new reference materials: MODAS-3 Herring Tissue (M-3 HerTis), MODAS-4 Cormorant Tissue (M-4 CormTis), and MODAS-5 Cod Tissue (M-5 CodTis) were prepared and certified on the basis of results of a worldwide intercomparison exercise. Independently of our proven method of establishing the certified and information values, the content of several essential and toxic elements was additionally determined by the use of ratio primary reference measurement procedures (definitive methods) based on radiochemical neutron activation analysis (RNAA) in the case of As, Cd, Co, Cr, Fe, Mo, Se, and U and isotope dilution mass spectrometry (IDMS) in the case of Hg, respectively. Good agreement of the established certified values and the results obtained by ratio primary reference measurement procedures confirmed the validity of the certification procedure. The total number of elements which could be certified amounted to 30, 21, 18 in M-3 HerTis, M-4 CormTis, and M-5 CodTis, respectively. The relative frequency of use of individual analytical techniques in this intercomparison campaign was calculated and discussed. Inductively coupled plasma mass spectrometry (ICP-MS) is now a dominant technique, followed by atomic absorption spectroscopy (AAS), NAA, and emission spectroscopy (ES). The decreasing share of NAA as compared to several earlier intercomparison exercises should be noticed. NAA is the only method in the array of highly sensitive methods of inorganic trace analysis, which is essentially free from blank. The lack of this method in the foreseeable future may be an obstacle in the prospective certification campaigns and may endanger the implementation of quality assurance in trace analysis.
