Pb isotope ratios in samples of diverse origin can be accurately measured without matrix separation.

The study investigated the total concentrations, toxicity, and health risks of 16 carcinogenic priority polycyclic aromatic hydrocarbons (PAHs) in street dust collected from urban areas Warsaw, Poland. Samples were analyzed across six granulometric fractions. Dust was 149 sampling points divided between Area 1 (central Warsaw districts, left bank Vistula River, dominated by traffic-related pollution) Areas 2 3 (suburban residential areas, right river).Street assessed both as a whole...

d26Mg values and 87Sr/86Sr ratios are used as tracers of calcite dolomite formation in the late Miocene Lake Bira. Mg Sr isotope were analyzed freshwaters brines that currently feed Sea Galilee (the modern remnant Bira) limestones dolostones comprising Bira Formation. waters (~0.89‰, ~0.7075) consistent with mixing mainly carbonate basaltic subsurface Ca-chloride (e.g., Tiberias Spa). The dolostone Formation range from ~ -1.0 to -3.5‰. -2.8 -1.8 ‰, respectively....

This study introduces a simplified purification method for analyzing 82Se/78Se isotope ratios in diverse natural samples using hydride generation MC-ICP-MS. Unlike the thiol resin method, which is time-consuming and sensitive to concentrations of reagents used at individual stages, our proposed alternative quicker, simpler, robust. The procedure involves coprecipitation selenium with iron hydroxide dissolution hydrochloric acid. Combining second cleanup stage achieves sufficient Se ratio...

Abstract The present study evaluated the level of heavy metal (HM) pollution in Vistula river sediments a highly urbanized Warsaw agglomeration (Poland). Magnetometry was used to assess by measuring fine fractions (0.071 mm and < 0.071 mm) collected from surface layer riverbank. magnetic methods (e.g., mass susceptibility χ , temperature-dependence susceptibility, hysteresis loop parameters) were supplemented microscopy observations chemical element analyses. results showed local impact...

In this study, we examine the possibility of detecting PTFE microparticles by ICP-qMS equipped with O 2 dynamic reaction cell (DRC) and operated in single-particle mode.

Liquid chromatography-high-resolution mass spectrometry was used for the first time to investigate impact of Se(IV) (10 mgSe L-1 as sodium selenite) on Allium cepa L. root proteome. Using MaxQuant platform, more than 600 proteins were found; 42 identified based at least 2 razor + unique peptides, score > 25, and found be differentially expressed in exposed versus control roots with t-test difference ±0.70 (p < 0.05, Perseus). caused growth inhibition decrease total RNA roots. Different...

In this work a high throughput, robust and sensitive method for the precise isotopic analysis of ⁸⁷Sr/⁸⁶Sr by coupling Ion Chromatography (IC) Multicollector Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS) is presented.

In this work, a method for the accurate and precise determination of 82Se/78Se isotope ratio in natural samples environmental biological origin, using multicollector inductively coupled plasma mass spectrometry wet mode without neither hydride generation nor separation Se, was developed. It based on optimized regression model with standard–sample bracketing (ORM–SSB) to efficiently correct instrumental isotopic fractionation/mass bias matrix effects. addition, three correction models SSB...

Relatively few studies have been focused so far on magnesium–isotope fractionation during plant growth, element uptake from soil, root-to-leaves transport and chlorophylls biosynthesis. In this work, maize garden cress were hydroponically grown in identical conditions order to examine if the carbon fixation pathway (C4, C3, respectively) might impact Mg-isotope chlorophyll-a. The pigment was purified plants extracts by preparative reversed phase chromatography, its identity confirmed...

Despite rich deposits of copper in SW Poland, their exploitation prehistory has not been confirmed, and the literature it is usually argued that raw materials processed Bronze Age were imported. This despite same area providing abundant evidence prehistoric metallurgy including casting moulds, tuyeres or crucibles. The concentration sites parts Sudety Mountains (in particular a region called Pogórze Kaczawskie) ores far from arable land may also indicate prospection activities this search...

Abstract This study identifies the lead ores used to produce artifacts by Romans between first and eighth centuries AD during construction of fort then town Novae (N. Bulgaria). For this purpose, samples were taken from pipes, joints columns pedestals, a ingot. The analyzed for isotopes results compared literature data Roman mines what is now Bulgaria, Greece, North Macedonia, Montenegro, Bosnia Herzegovina, Italy, Germany, Romania. Pb isotope indicate that earlier stages Novae's...

Abstract The Bronze and Early Iron Ages witnessed a significant increase in trade relations driven by the search for valuable metals. This paper presents new insights into use of galena from Silesia Krakow Upland region southern Poland, known as ‘Olkusz ore deposits’, within context metal ores prehistoric Europe. Eleven lead‐based ornaments Lusatian Urnfield Culture cemeteries were examined using lead isotope analysis. majority these found to be made local ore, which provides evidence early...

In this work, a method for the accurate and precise determination of Ge isotope ratio in synthetic water natural samples geological origin using multicollector inductively coupled plasma mass spectrometry (MC-ICPMS) with hydride generation was developed.
