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...
The first national human biomonitoring in Slovenia surveyed cadmium (Cd), lead (Pb), mercury (Hg), arsenic (As), manganese (Mn), selenium (Se), copper (Cu) and zinc (Zn) a childbearing population (18–49 years) selected from lactating primiparous women men (N = 1084). overall aim was to estimate trace elements' levels geographical variations order identify sources of possible exposures set the reference values. study evenly 12 areas across Slovenia, including rural, urban known or potentially...
There are extensive data on the toxicity of glyphosate (GLY) based herbicides (GBH), however interpretation some (e.g. carcinogenic effect) subject to controversy. For appropriate health risk assessment more exposure levels in general population, especially susceptible groups such as pregnant women, elderly and children needed. The aims present study were estimate GLY its major metabolite aminomethylphosphonic acid (AMPA) adolescents living agricultural areas, identify possible determinants...
As population growth and climate change add to the problem of water scarcity in many regions, argument for using treated wastewater irrigation is becoming increasingly compelling, which makes understanding risks associated with uptake harmful chemicals by crops crucial. In this study, 14 emerging concern (CECs) 27 potentially toxic elements (PTEs) was studied tomatoes grown soil-less (hydroponically) soil (lysimeters) media irrigated potable LC-MS/MS ICP-MS. Bisphenol S, 2,4 bisphenol F,...
The impact of exposure to lead on child neurodevelopment has been well established. However, sex differences in vulnerability are still not fully explained. We aimed at evaluating the effect a low-level exposure, as measured between 20 24 weeks pregnancy and cord blood, developmental scores up months age 402 children from Polish Mother Child Cohort (REPRO_PL). Additionally, sex-dependent susceptibility this very early stage psychomotor development was assessed. blood levels were analyzed...
Main text KRISS and NMIJ jointly coordinated the CCQM-K158 comparison on elements inorganic As in polished rice flour. The study comprised two parts, Part A B. Successful participation formal international comparisons is essential for documenting calibration measurement capability claims (CMCs) by national metrology institutes (NMIs) designated (DIs). specifically supports CMCs within food category, corresponding to sample matrix labeled "High organic content" new CC table broad claims....
This study used elemental and stable isotope composition to characterize Slovenian truffles multi-variate statistical analysis classify according species geographical origin. Despite the fact that shared some similar characteristics with samples originating from other countries, differences in element concentrations suggest respective truffle may respond selectively nutrients a certain soil type under environmental conditions. Cross-validation resulted 77% correct classification rate for...
Dietary supplements based on algae, known for their nutritional value and bioactive properties, are popular products among consumers today. While commercial algal regarded safe by numerous studies, information about the production origin of such is scarce. In addition, dietary not as strictly regulated food medicinal drugs. We characterized different (kelps: Laminariales, Spirulina spp., Chlorella Aphanizomenon flos-aquae ), obtained Slovenian market, elemental composition (X-ray...
Toxic elements emitted from the Pechenganickel complex on Kola Peninsula have caused concern about potential effects local wild food in border regions between Norway, Finland and Russia. The aim of this study was to assess Ni, Cu, Co, As, Pb, Cd, Hg concentrations foods these regions. During 2013-2014, we collected samples different berry, mushroom, fish, game species sites at varying distances Ni-Cu smelter all three Our results indicate that is main source As foods, whereas sources Pb Cd...
The maternal diet and living environment can affect levels of chemical elements fatty acid (FA) composition their stable isotopes (δ13CFA) in human milk. Information obtained from questionnaires is frequently imprecise, thus limiting proper associations between external internal exposures as well health effects. In this study, we focused on seafood a source potentially toxic essential nutritional FAs. Concentrations selected milk (As, Cd, Cu, Mn, Pb, Se Zn) were determined using inductively...
The objective of this study was to optimize sample preparation using a microwave system (ULTRAWAVE) for the determination multi-elemental composition fruit samples by inductively coupled plasma mass spectrometry (ICP-MS) detection. Standard reference materials, SRMs (SRM 1547 Peach Leaves, SRM 1570a Spinach 1568b Rice Flour, 1567b Wheat Flour), grain RM 8436 Durum and were digested in concentrate nitric acid (1 mL HNO3 or 2.5 HNO3) mixture hydrogen peroxide (2.5 1 H2O2) simultaneous 27...
Abstract Hg isotope analysis in samples from background regions is constrained by the presence of low concentration and therefore requires a pre-concentration method. Existing methods are long sample processing time limited loading capacity. Using foliar as test case, an optimized method presented that involves microwave-assisted digestion for with addition pre-digestion step. Microwave-digested CRMs were transferred to impinger, reduced SnCl 2 , collected 2.25 mL concentrated inverse aqua...
Traceable determination of atmospheric mercury (Hg) represents a major analytical problem due to low environmental concentrations. Although Hg pre-concentration on activated carbon (AC) traps is simple method for sample collection, difficult complex matrix that cannot be easily digested using wet chemistry. Two approaches loading iodinated AC, the purging elemental (Hg0) and spiking solution standard reference material (SRM), were used test whether SRM AC can traceable collected as Hg0....
The objective of the present study was to evaluate relation between maternal blood levels selected toxic and potentially elements (manganese (Mn), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), cadmium (Cd), lead (Pb) mercury (Hg)) birth weight their new-borns in a Slovenian population, taking into account socio-demographic characteristics dietary habits.535 women from 12 regions Slovenia were recruited at delivery.Maternal collected 1.5 months after birth.Associations a) predictors...
Introduction: HEALS (online access: www.heals-eu.eu) aims to refine an integrated approach perform environment-wide association studies (EWAS) explain the exposome for improved understanding of links between genome, and disease. is at present largest EU project on this issue. Guidelines biomarkers exposure (BoE) were developed characterize internal exposures in EWAS. Methods: Fact sheets about human biomonitoring (HBM) selected environmental stressors provided using >800 references...
