Most previous measurements of oxidized mercury were collected using a method now known to be biased low. In this study, dual-channel system with an detection limit 6-12 pg m
Abstract The Mediterranean Region has a long lasting legacy of mercury mining activities and high density sub-marine volcanoes that strongly contributed to its budget. In the last forty years, there have been recorded increases in concentrations biota spurred growing number research assess impact pollution on human health environment. Field investigations quantify marine led large amount experimental data scattered many peer-reviewed publications making it difficult for modelling...
Abstract. The monitoring of low gaseous elemental mercury (GEM) concentrations in the atmosphere requires continuous high-resolution measurements and corresponding calibration capabilities. Currently, for GEM is still an issue at ambient (1–2 ng m−3). This paper presents a flow GEM, traceable to NIST 3133 Standard Reference Material (SRM). approach was tested using direct analyser based on atomic absorption spectrometry with Zeeman background correction (Zeeman AAS). produced standard...
Studying atmospheric mercury (Hg) isotopic composition is crucial for understanding the complex biogeochemical cycling of mercury, a global pollutant with significant environmental and health impacts. Mercury isotopes provide valuable information about sources, transformation processes, deposition pathways Hg in environment, allowing researchers to trace its movement identify contributions from natural versus anthropogenic sources. Studies have gained momentum recent years, over 80% relevant...
Mercury (Hg) emissions into the atmosphere have significant environmental and health impacts, making accurate measurement calibration of Hg crucial for effective monitoring mitigation strategies. Measuring different forms atmospheric mercury, such as gaseous elemental mercury (GEM), oxidized (GOM) particulate-bound (PBM), their behavior in both ambient air is essential developing comprehensive approaches to control pollution. Currently, common calibrations GOM rely on liquid evaporative...
Understanding atmospheric mercury chemistry is the key for explaining biogeochemical cycle of and improving predictive capability computational models. Increased efforts are being made to ensure comparable Hg speciation measurements in air through establishing metrological traceability. While traceability elemental has been recently set, this by no means case gaseous oxidized (GOM). Since a calibration unit suitable traceable GOM calibrations based on evaporation HgCl2 solution was...
The number of atmospheric mercury (Hg) monitoring stations is growing globally. However, there are still many regions and locations where Hg limited or non-existent. Expansion the network could be facilitated by use cost-effective methods. As such, biomonitoring passive offer a unique alternative to well-established active measurements, since they do not require power supply minimal workload operate. (lichens mosses) air samplers (PASs) (various designs with synthetic materials) has been...
The outputs of Hg 0 and II gas generators were validated by isotope dilution with a dynamically generated 199 enriched standard produced continuous cold vapour ICP-MS detection, thereby providing SI-traceability primary standards.
Calibration is crucial in quantitative analysis, ensuring the traceability of standards for an accurate comparison results. In mercury determinations, a gas calibrator unit containing liquid used calibration by injecting headspace volumes via syringe. The Dumarey equation has been over 35 years to calculate concentration, aligning closely with saturated vapor pressure equations. However, 2006 Huber yields different values, creating discrepancies. This paper compares calibrations using...
Methylmercury is a bioaccumulative neurotoxin that poses severe risks to marine ecosystems and human health worldwide. Hydrothermal systems submarine volcanoes are natural sources of mercury, yet the magnitude emissions, their transport, impact on remain poorly understood. Quantifying mercury fluxes essential understanding anthropogenic perturbations guiding effective reduction strategies. We investigate hydrothermal inputs at Tonga volcanic arc local ecosystem. Our results show activity in...
Atmospheric mercury measurements carried out in the recent decades have been a subject of bias largely due to insufficient consideration metrological traceability and associated measurement uncertainty, which are ultimately needed for demonstration comparability results. This is particularly challenging gaseous HgII species, reactive their ambient concentrations very low, causing difficulties proper sampling calibration. Calibration atmospheric exists, but barriers reliable calibration most...

Abstract. A primary mercury gas standard was developed at Van Swinden Laboratory (VSL) to establish an International System of Units (SI)-traceable reference point for concentrations emission and background levels in the atmosphere. The majority concentration measurements are currently made traceable empirically determined vapour pressure mercury. can be used accurate precise calibration analytical systems measuring air. It has been especially support related ambient air monitoring (1–2 ng...
Abstract. Atmospheric mercury speciation is of paramount importance for understanding the behavior once it emitted into atmosphere as gaseous elemental (GEM), oxidized (GOM) and particulate-bound (PBM). GOM PBM can also be formed in atmosphere; their sampling most problematic step atmospheric speciation. with traps composed KCl sorbent materials trapping solutions are commonly used methods, although research conducted them at ambient air concentrations limited. The results specificity test...
We have analyzed concentrations of Mo, Re and U in the suspended particles, water column, underlying carbonate-dominated sediments pore waters two contrasting marine lakes situated on Adriatic Coast Croatia. Our data are first for these lakes. Rogoznica Lake is mainly euxinic, but subject to occasional oxygenation events, whereas Mljet Island's Malo Jezero currently oxic year around historically was seasonally euxinic. These characteristics make useful testing grounds redox proxies. devote...
This work reports the development of ultralight interwoven ultrathin graphitic carbon nitride (g-CN) nanosheets for use as a potential adsorbent in passive sampler (PAS) designed to bind Hg2+ ions. The g-CN were prepared from bulk synthesised via modified high-temperature short-time (HTST) polycondensation process. crystal structure, surface functional groups, and morphology characterised using battery instruments. results confirmed that as-synthesized product is composed few-layered...
