Research paper thumbnail of Variability of gaseous elemental mercury concentrations in the northern Adriatic coastal area (Gulf of Trieste-Marano and Grado Lagoon)

Gaseous elemental mercury (GEM) concentrations in pristine, urban and mercury (Hg)-contaminated s... more Gaseous elemental mercury (GEM) concentrations in pristine, urban and mercury (Hg)-contaminated sites, over the period from May 2013 to June 2015, were monitored for their temporal dynamics of variability. Results of GEM measurements along a E-W transect from the city of Trieste (NE Italy) to the Marano and Grado Lagoon were recorded during periods of more than 24 hours. Most of the monitored sites are affected by the presenceof Hg in soils, sediments and waters, since the Isonzo River, carrying Hg-contaminated sediments coming from the Idrija (Slovenia) mining district, is the major fluvial input ofthe Gulf of Trieste. Two LUMEX RA95M devices were used to analyze GEM concentrations at fixed intervals (1 to 5 sec., depending on the availability of continuous electricity power) by meansof atomic absorption spectrometry with Zeeman effect. This is a technique usually employed during GEM monitoring surveys worldwide. Results indicate that GEM concentrations are systematically low (2-5 ng m-3) in the study area. Restricted areas with the highest GEM values were found in the proximity of the Isonzo River mouth and in the alluvial plain between the river and the Lagoon (East sector). Here, soils show high concentrations of Hg (up to 30 mg/kg) since the whole area belonged to the former lagoon environment and it was drained in 1920-30 for agricultural purposes. In these areas, GEM concentrations were higher (up to 30-50 ng m-3) duringnight periods and in particular during wind cessation moments, although they are scarce and short in time in this coastal area

The link between microbial production of toxic methylmercury (MeHg), and its bioaccumulation and biomagnification in marine food webs of the gulf is at present rather poorly characterized but is critical to understanding the links between sources and higher trophic levels, such as fish, that are ultimately vectors of human and wildlife exposure. This overview explores three major topics: (i) the microbial biogeochemical cycling of Hg in the area, (ii) the trophic transfer and bioaccumulation of MeHg in pelagic and benthic marine food webs, and (iii) human exposure to Hg through marine fish and shellfish consumption. These are important goals since the Gulf of Trieste is an area of great economical importance.

In this study, diurnal gaseous Hg exchanges were seasonally evaluated by means of a floating flux chamber in two freshwater environments impacted by anthropogenic sources of Hg, specifically historical mining activity (Solkan Reservoir, Slovenia) and the chlor-alkali industry (Torviscosa dockyard, Italy), and in a pristine site, Cavazzo Lake (Italy). The highest fluxes (21.88 ± 11.55 ng m−2 h−1) were observed at Solkan, coupled with high dissolved gaseous mercury (DGM) and dissolved Hg (THgD) concentrations. Conversely, low vertical mixing and saltwater intrusion at Torviscosa limited Hg mobility through the water column, with higher Hg concentrations in the deep layer near the contaminated sediments. Consequently, both DGM and THgD in surface water were generally lower at Torviscosa than at Solkan, resulting in lower fluxes (19.01 ± 12.65 ng m−2 h−1). H...

The mining activity, abandoned before the introduction of environmental laws, led to the contamination of soil, water and sediments, where high concentrations of potentially toxic elements (PTEs) can be found. Estuarine sediments must be dredged in order to allow for navigation, and their destination must be managed following guidelines based only on the total concentration of contaminants. The effect of resuspension on the cycling of mercury (Hg) and arsenic (As) between the sediment and water column was investigated in a mesocosm study. Four experiments were conducted in three Asturian estuaries based on samples collected from sites impacted by Hg and As and periodically subjected to dredging activities. Designed to mimic the resuspension of particles, all the experiments revealed that the release of Hg and As species do not depend on the total concentration in the sediments. In summary, it is ev...

Their behaviour is carefully investigated in environmental studies due to their key role in biogeochemical processes involving water, sediments and biota. Natural concentrations of trace elements in these matrices primarily depend on the local lithological and mineralogical characteristics. Unfortunately, as a result of human activities, the contemporary environment has been affected by several additional sources of trace elements, such as potentially toxic metals and metalloids. If the anthropogenic inputs of these elements in the natural systems exceed the local background values, we can expect to observe some effects on their biogeochemical cycles. These may also result in their anomalous accumulation in biota and, possibly, in human beings through fish and mussel consumption. Estuaries represent unique water systems, a vital link between the land and the sea. Due to mixing of fresh and seawater, estuaries are characterized by pronounced gradient of many parameters such as salinity, temperature, pH, redox potential as well as suspended particle matter composition. Besides, they often act as a trap for material brought by rivers, which may also include various contaminants, included potentially toxic elements, associated with anthropogenic activities. The primary aim of this work was to investigate the geochemical characteristics of the present sediments of the Nal\uf3n River estuary compared to the local geochemical background in order to assess possible anomalies due anthropogenic contributions which can have altered their lithogenic properties. For this purpose, spatial and temporal distributions of major and trace elements in the sediments were deeply investigated

The former are due to a chemical complex which has been producing cellulose, chlor-alkali and textile artificial fibers since the ‘40s [1]. The second input comes from the Isonzo (So•a) River, the most relevant source of Hg contamination in the northern Adriatic Sea, caused by the Idrija Hg mine (NW Slovenia) since the 16 century [2]. The “MIRACLE” Project was promoted by the Commissario Delegato of MG Lagoon in 2008, in order to test the coexistence of clam farming and the possible extension of rearing activities in areas with high Hg contamination in the sediments. The project involved an international collaboration among Italian, Slovenian and US scientists, applying a broad range of expertise at various scales. In the framework of the “MIRACLE” Project, one of the subtasks was to determine the historical evolution of Hg accumulation in t...

La aplicaci\uf3n al estudio de \uedndices normalizados de referencia como el \ucdndice de Geoacumulaci\uf3n o el Factor de Enriquecimiento han mostrado que a determinadas profundidades los sedimentos de las marismas presentan concentraciones especialmente elevadas en As, Pb y Zn, y estas anomal\uedas geoqu\uedmicas se consideran atribuibles a la actividad antropog\ue9nica como fuente principal de aporte

We focus on primary production (PP) in the water column and benthos, the sedimentation and horizontal transport of particlulate organic matter (POM), and biogeochemical responses of the benthic community to sedimentation. Phytoplankton net PP (NPP) remains higher in CB (five times that in NAS) and rates of benthic respiration appear greater in CB (three times that in NAS). A lower fraction of phytoplankton NPP plus riverine inputs of POM is deposited to sediments in the NAS (23%) compared to CB (83%). A high percentage of organic matter inputs are respired by plankton and exported in the NAS and CB, and benthic communities respired a similar percentage of POM (86% in the NAS, 92% in CB). Net release of regenerated N from the benthos (0.2\u20130.3 mol N m 122 year 121) is also similar in both systems. At 0.53 mol N m 122 year 121, rates of benthic denitrification are higher in CB than in the NAS (0.3 mol N m 122 year 121), and the NAS appears to bury similar fractions of deposited N and P (N: 23% in NAS, 19% in CB; P: 50% in NAS, 45% in CB). To address the impacts of future climate\u2010driven warming and acceleration of the water cycle, we recommend a return to sustained monitoring combined with numerical simulations to allow improved understanding and predictions of changes in P\u2013B interactions
