This study investigates the relationships among Ni, Cd and Pb's different chemical forms determined by methodologies in coastal transitional waters across a broad geographical scale. Concentrations were measured spot samples through passive sampling (DGT). High variability of metal concentrations was found sites due to natural water fluctuations rather than given or method. Total dissolved lower EQS-WFD values. The labile fractions Pb, Anodic Stripping Voltammetry DGT-ICPMS, highly...
The current study evaluates the effect of seawater physico-chemical characteristics on relationship between concentration metals measured by Diffusive Gradients in Thin films (DGT) passive samplers (i.e., DGT-labile concentration) and concentrations discrete water samples. Accordingly, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to measure total dissolved metal samples labile obtained DGT samplers; additionally, lead cadmium conditional fractions were determined Anodic...
This protocol was developed based on the knowledge acquired in framework of Interreg MONITOOL project (EAPA_565/2016) where extensive sampling campaigns were performed transitional and coastal waters covering eight European countries. It provides detailed procedures guidelines for these waterbodies by concurrent collection discrete water samples deployment Diffusive Gradient Thin-films (DGT) passive samplers measurement trace metal concentrations. In order to facilitate application this...
Abstract Integrative passive samplers, such as DGT (Diffusive Gradients in Thin-films), are identified European Technical Guidance Documents promising tools to improve the quality of assessment, context WFD (EU Water Framework Directive). However, results cannot yet be used directly a regulatory framework assess chemical status water bodies, labile concentrations compared metal AA-EQS marine (Annual Average Environmental Quality Standard) established by WFD, which defined dissolved...
The presence of ten metals (Cd, Ni, Pb, Cr, Cu, Zn, Al, Fe, Mn, and Co) was investigated in the final discharge six facilities, including four wastewater treatment plants, which were continuously discharging treated to coastal environment Gran Canaria Island. A four-day sampling campaign carried out at each facility July 2020, both spot samplings technique diffusive gradient thin-film (DGT) measure total dissolved situ labile metal fraction, respectively. After necessary sample preparation...
This good practice guide is focused on the DGT devices, which are most widely used passive sampler for metals, covering following aspects: ■ Principle Handling sampling devices metals Estimation of appropriate field deployment time A Good Practice Guide Use DGTs Passive device preparation and assembly Selection site safety precautions retrieval Extraction analytes from Analysis Calculations
Wastewater treatment plants (WWTPs) have been identified as significant point sources of microlitter particles (MPs) released into the environment. Simultaneously, they play a crucial role in effectively removing substantial amount MPs originated from domestic and industrial activities. This study evaluates presence chemical composition within range 5 mm to 25 µm effluents three WWTPs Canary Islands, each undergoing distinct processes: pretreatment (PRET), activated sludge (AS), membrane...
The MONITOOL project (2017-2023) was carried out to describe the relationships between total dissolved and labile metal concentrations measured in spot water samples concurrently deployed Diffusive Gradients Thin-films (DGTs) passive samplers, respectively. ultimate aim adapt existing marine Environmental Quality Standards (EQS water) for DGTs, enabling their use context of European Directives (the Water Framework Directive (WFD) Marine Strategy (MSFD)). Time-integrated provided by...
In highly dynamic systems, such as transitional and coastal waters, establishing their chemical status is challenging. MONITOOL an exciting European project consisting of 16 Partners covering the Atlantic region from Canary Islands to Scottish Highlands Islands, which aims address this complex analytical challenge, responding Directive demands for assessment waters. Diffusive Gradient in Thin Films (DGT), passive samplers (PS), general, are already widely used investigative monitoring there...
In order to move forward in the acceptance of a novel contaminant monitoring technique (Diffusive Gradients Thin-films: DGT) for chemical assessment marine water bodies, sensu WFD, an Inter-Laboratories Comparison (ILC) exercise (nine Europeans laboratories) was organized framework Interreg Atlantic Area MONITOOL project, which focused on use DGT measurement WFD priority metals (Cd, Ni and Pb). This ILC designed identify critical handling analytical steps when working with devices establish...
