The microalgae Spirulina may be a popular dietary supplement rich in essential nutrients and vitamins, but oversight of the industry, general, remains limited, increasing incidents adulteration, misbranding, undeclared ingredients together with misleading claims create potential risks. In response, this study characterized elemental, amino acid fatty content commercially available supplements Slovenia using EDXRF, ICP-MS GC-MS compared results their nutritional declaration. gathered data...
ABSTRACT A detailed localization of elements in leaf tissues the field‐collected Cd/Zn hyperaccumulator Thlaspi praecox (Brassicaceae) growing at a highly metal‐polluted site was determined by micro‐proton‐induced X‐ray emission (micro‐PIXE) order to reveal and compare nutrient non‐essential element accumulation patterns case multiple metal within particular tissues, including distribution between apoplast symplast regions. On larger scans, highest concentrations metals were observed...
Isotope parameters (δ13Choney, δ13Cprotein, δ15N) were determined for 271 honey samples of 7 types (black locust, multifloral, lime, chestnut, forest, spruce, and fir honeys) from 4 natural geographical regions Slovenia. Carbon nitrogen stable isotope ratios measured to elucidate the applicability this method in identification botanical origin adulteration. Only 2.2% adulterated according internal standard carbon ratio analysis method. Botanical did not have any major influence on profiles;...
Typha latifolia is a plant species widely used for phytoremediation. Accumulation, localization and distribution of Pb mineral nutrients were investigated in roots, rhizomes leaves grown at 0, 50, 100 250 μM concentrations pot experiment under controlled conditions. Bulk elemental determined by X-ray fluorescence (XRF) spectroscopy whereas micro-proton-induced emission (micro-PIXE) was element root rhizome tissues. Gradual increase bulk observed roots treated with increasing concentrations,...
Abstract This is the first study to use moss transplants as a biomonitoring technique and inductively plasma mass spectrometry investigate airborne potentially toxic element pollution air quality in urban areas on regional scale across nine Southeastern European countries. The mosses bags were exposed for 2 months during winter season (2019/2020) at five sites each of selected next (AQ) monitoring stations. concerning different land classes (typical urban, residential, background, rural...
Celtis australis is a deciduous tree commonly known as Mediterranean hackberry or the European nettle tree. The fruit of are seldom used for nutritional purposes. and physicochemical properties ripe from Istria (Marasi village near Vrsar, Croatia) were determined, including water, total fiber, protein, vitamin, mineral, phenolic contents. This analysis demonstrates that valuable source dietary vitamins, pigments such lutein, β-carotene, zeaxanthin, tocopherols. seasonal differences...
Carbon nanocomposites containing iron-based nanoparticles are attractive materials for the catalyst supports used magnetic (induction) heating catalysis. The metallic, soft-magnetic iron provide local of support in an alternating field and ensure rapid separation nanocomposite particles from reaction suspensions. In this work, carbon were prepared by annealing precursor consisting iron-oxide dispersed a carbohydrate matrix. was conducted at 600 °C 750 Ar atmosphere. At both temperatures...
This work on the botanical origin of various types honey produced in Slovenia and based mineral content analyses by total reflection X-ray spectrometry (TXRF) is a continuation this group's preliminary (Golob, T.; Doberšek, U.; Kump, P.; Nečemer, M. Food Chem. 2005, 91, 593−600), which introduced analytical methodology employed only simple statistical evaluation examined possibility to determine samples via elemental content. A much more comprehensive study 264 major harvested 2004, 2006...
