Abstract Calibrations in LA-ICP-MS are typically very time-consuming and complex, as they need to be matched the samples being measured sectioned on a microtome. Alternatively, gelatin can droplet form or section, which is more recent development. In this study, we report investigations where hot multi-element solutions placed linear fashion microscopic slides conduct comparative statistical observations between doped tissue homogenates from liver lung. The served both (complete ablation) calibration standards (partial for verification purposes. We explored effects of different laser fluences (0.50–1.50 J/cm 2 ), contents (0.3–20.0%) section thicknesses (10–30 µm). To do this, evaluated by calculating median mean values over entire with without removal elementary spikes (de-spiking). A reduction distribution was achieved averaging. data normalized using 13 C an internal standard. these experiments under measurement conditions, it observed that selected fluences, contents, did not visibly affect results, making them comparable. Each sample could assessed each calibration, allowing determination expected reference values. Despite interruptions operation, due high number measurements, calibrations analyzed one run, no negative stopping starting were observed. Graphical abstract

For several reasons, mainly cost and local productivity, the world population does not have access to a balanced diet that contains all macro micronutrients necessary maintain physiological functions for healthy life. Nutritional education, supplementation, consuming enriched (or fortified) foods appear as alternatives supply daily demands minimize malnutrition. Adding essential elements salts (e.g., iron, calcium, zinc) ready-to-eat processed foods, such milk, flour, juices is already adopted in countries. The choice of compound be added, well transport vehicle (foods), must very evaluated since cost, long-term consumption, bioavailability added chemical species are imperative ensure nutritional quality food.1 Another alternative produce cultivating an medium (Figure 1), adding soil or nutritive solution (hydroponic procedure), irrigating leaves, immersing seeds.2 In this case, used enrich food absorbed, translocated, accumulated edible part.2 Studies shown iron enrichment adzuki beans using nitrate chloride was unsuccessful inorganic interact strongly with antinutrients (tannins phytates) present roots, forming insoluble complexes preventing their translocation.3 Alternatives found overcome obstacle were by applying EDTA (ethylenediaminetetra-acetic acid)3 nanoparticles, encapsulated.4 nanoparticle application has been gaining prominence agriculture, aiming carry fertilizer, pesticides, nutrients stimulate plant growth increase micronutrient availability absorption efficiency.5,6 Besides interaction between antinutrients, evaluating competition elemental important, because synergistic antagonistic effects can observed. both cases, other components cultivation medium, altering its composition when compared cultivated conventional conditions. effect selenium mercury observed mushrooms, while lead selenium.7,8 Finally, it if promotes production non-bioavailable toxic species.
