Methylmercury determination in freshwater biota and sediments: Static headspace GC-MS compared to direct mercury analyzer

Autor: Lucia Valsecchi, Claudio Roscioli, Alfredo Schiavon, Laura Marziali

Publikováno v: MethodsX, Vol 8, Iss , Pp 101581- (2021)

We developed and compared two analytical methods for determination of MeHg in freshwater biota and sediments, by: I) simplified static headspace GC-MS using internal standard (IS) isotope dilution quantification, after microwave acid digestion and aq

Zooplankton as Mercury Repository in Lake Maggiore (Northern Italy): Biomass Composition and Stable Isotope Analysis

Autor: Laura Marziali, Roberta Piscia, Lucia Valsecchi, Claudio Roscioli, Marina Manca

Publikováno v: Water, Vol 14, Iss 5, p 680 (2022)

Total mercury (THg) and methylmercury (MeHg) concentrations were analyzed in zooplankton (≥450 and ≥850 µm size fractions) collected seasonally over 6 years in Lake Maggiore (Northern Italy), characterized by a legacy mercury contamination. Anal

Mercury Bioaccumulation in Benthic Invertebrates: From Riverine Sediments to Higher Trophic Levels

Autor: Laura Marziali, Claudio Roscioli, Lucia Valsecchi

Publikováno v: Toxics, Vol 9, Iss 9, p 197 (2021)

Riverine sediments are important sites of mercury methylation and benthic invertebrates may be indicators of Hg exposure to higher organisms. From 2014 to 2018, sediments and invertebrates were collected along a mercury gradient in the Toce River (No

Mercury Bioavailability in Fluvial Sediments Estimated Using Chironomus riparius and Diffusive Gradients in Thin-Films (DGT)

Autor: Laura Marziali, Lucia Valsecchi

Publikováno v: Environments, Vol 8, Iss 2, p 7 (2021)

Mercury bioavailability was assessed by exposing the dipteran Chironomus riparius for the whole life cycle to legacy-contaminated fluvial sediments (0.038–0.285 mg Hg kg−1 d.w.) and analyzing tissue concentrations in larvae at different exposure

Phosphate adsorption by riverborne clay sediments in a southern-Italy Mediterranean reservoir: Insights from a 'natural geo-engineering' experiment

Autor: Diego Copetti, Lucia Valsecchi, Gianni Tartari, Marina Mingazzini, Maria Teresa Palumbo

Publikováno v: The Science of the total environment. 856(Pt 2)

This paper reports data from a southern-Italy reservoir (Lake Occhito) characterized by a strong riverborne sediment transport. Main hydrochemical, trophic, and nutrient variables were measured (over a twelve-month period) in both lake and tributarie

Twenty-year sediment contamination trends in some tributaries of Lake Maggiore (Northern Italy): relation with anthropogenic factors

Autor: A. Marchetto, Stefano Tasselli, Franco Salerno, Claudio Roscioli, Licia Guzzella, Alfredo Schiavon, Laura Marziali, Lucia Valsecchi

Publikováno v: Environmental Science and Pollution Research. 28:38193-38208

Lake tributaries collect contaminants from the watershed, which may accumulate in lake sediments over time and may be removed through the outlets. DDx, PCB, PAH, PBDE, and trace element (Hg, As, Cd, Ni, Cu, Pb) contamination was analyzed over 2001–

Climate Change Impacts on Sediment Quality of Subalpine Reservoirs: Implications on Management

Autor: Marziali Laura, Gianni Tartari, Franco Salerno, Lucia Valsecchi, Clara Bravi, Erika Lorenzi, Pietro Genoni, Licia Guzzella

Publikováno v: Water, Vol 9, Iss 9, p 680 (2017)

Reservoirs are characterized by accumulation of sediments where micropollutants may concentrate, with potential toxic effects on downstream river ecosystems. However, sediment management such as flushing is needed to maintain storage capacity. Climat
