This Technical Guidance Document on Biota Monitoring (the Implementation of EQSbiota) aims to facilitate the implementation environmental quality standards (EQS) in biota under Water Framework Directive by addressing particular sampling strategies appropriate for monitoring programmes designed assess compliance with biota EQS. It is Guidance No. 32 series guidance documents prepared support the Common Strategy (CIS) Directive. It elaborates extensively content 25 Chemical Monitoring...

Summary: Per- and polyfluoroalkyl substances (PFASs) are man-made chemicals that contain at least one perfluoroalkyl moiety, –CnF2n–. To date, over 4,000 unique PFASs have been used in technical applications consumer products, some of them detected globally human wildlife biomonitoring studies. Because their extraordinary persistence, environmental exposure to will be a long-term source concern. Some such as perfluorooctanoic acid (PFOA) perfluorooctanesulfonic (PFOS) investigated...

While several sources of per- and polyfluoroalkyl substances (PFAS) are known, their use in consumer household products is far less explored. The aim this study was to provide comprehensive bottom-up analysis the types concentrations PFAS reported literature over past decade. A total 52 studies revealed 107 belonging 15 different categories 1040 products. highest number tested were from USA (n=389) followed by Czech Republic (n=111). Mean firefighting products, textile finishing agents...

The European Commission Implementing Decision EU 2015/495 included three steroidal estrogens, namely 17α-ethinyl estradiol, 17β-estradiol, and estrone, in the so-called "watch list" of Water Framework Directive (WFD). monitoring these compounds is difficult because detection limits majority available analytical methods cannot achieve very low target concentrations required to meet proposed environmental quality criteria. In 2014, a combined Science-Policy Interface/Chemical Monitoring...

Abstract Concentrations in fish of per‐ and polyfluoroalkyl substances (PFAS) were reported for 7 deep lakes the European subalpine area: Lakes Geneva, Lugano, Maggiore, Iseo, Como, Garda, Mergozzo; one shallow lowland lake (Varese); 2 high‐altitude alpine (>2000 m a.s.l). Fillets and, selected cases, other body fractions (viscera, liver, residual carcass) from 8 species analyzed. The possibility harmonizing monitoring protocols was tested. Results suggest that sampling season is not...

There is growing concern for the wide use ofperfluorooctanoic acid (PFOA) because of its toxic effects on environment and human health. A new compound - so called C6O4 (perfluoro ([5-methoxy-1,3-dioxolan-4-yl]oxy) acetic acid) was recently introduced as one alternative to traditional PFOA, however this done without any scientific evidence when dispersed into environment. Recently, Regional Agency Protection Environment Veneto (Italy) detected high levels in groundwater Po river, increasing...

Graphene nanosheets have outstanding adsorption efficiency toward organic molecules but the potential as sorbent for water purification is strongly limited by tedious recovery of after treatment, which can cause secondary contaminations. Here, we demonstrate that graphene oxide (GO) and reduced GO (rGO) aggregation in tap water, enabling their separation dead-end microfiltration (MF) on commercial polymeric hollow fiber modules. No evidence GO/rGO contamination was found microfiltered...

Nontargeted screening (NTS) utilizing liquid chromatography electrospray ionization high-resolution mass spectrometry (LC/ESI/HRMS) is increasingly used to identify environmental contaminants. Major differences in the efficiency of compounds ESI/HRMS result widely varying responses and complicate quantitative analysis. Despite an increasing number methods for quantification without authentic standards NTS, approaches are evaluated on limited diverse data sets with chemical coverage collected...

The biomagnification of mercury, polychlorobiphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs) perfluoroalkyl acids substances (PFASs) was evaluated in the trophic web Lake Mergozzo, a small deep Italian subalpine lake, which has been chosen because it is protected environment, discharges into lake are mostly avoided. Carbon source relative levels were calculated by using 13C 15N stable isotopes, respectively, magnification factors (TMFs) derived. Zooplankton...
