I CoGas projektet utvecklades en provtagningsutrustning och en fältmetod som möjliggör in-situ provtagning av gas från fiberbankar. Detta för att kunna kvantifiera utsläpp av växthusgaser samt vilka de halvflyktiga föroreningarna är som följer med gasen från fiberbankarna. En övergripande målsättning med projektet har varit att bidra med kunskap om...

Antibiotics are critical components of modern health care. Protecting their efficacy through managing the rise in antibiotic resistance is therefore a global concern. It is not known to what extent environmental pollution from antibiotics contributes to the development of resistance, but encountered concentrations are frequently above concentration...

This document aims to establish a common understanding on the role of sediment in achieving the objectives of the Water Framework Directive, and to provide guidance on how to address pressures on sediment quantity and sediment contamination, in the context of the River Basin Management Plans, and also other policies’ planning instruments. It covers...

The Baltic Sea is among the most polluted seas worldwide. Anthropogenic contaminants are mainly introduced via riverine discharge and atmospheric deposition. Regional and international measures have successfully been employed to reduce concentrations of several legacy contaminants. However, current Baltic Sea monitoring programs do not address comp...

A specific sub-group for Effect-Based Methods (EBM) was established with representatives from nine Member States (MS), Switzerland and several stakeholders in the context of the Common Implementation Strategy (CIS) for the Water Framework Directive (WFD), specifically the Working Group Chemicals. The Main Objective of the activity of the group has...

There is growing understanding that the environment plays an important role both in the transmission of antibiotic resistant pathogens and in their evolution. Accordingly, researchers and stakeholders world-wide seek to further explore the mechanisms and drivers involved, quantify risks and identify suitable interventions. There is a clear value in...

The interactions between academic research and regulatory assessment of chemicals may in theory seem straightforward: researchers perform studies, and these studies are used by regulators for decision-making. However, in practice the situation is more complex, and many factors decide a research study’s regulatory use. According to several EU chemic...

The Water Framework Directive (WFD), 2000/60/EC, requires an integrated approach to the monitoring and assessment of the quality of surface water bodies. The chemical status assessment is based on compliance with legally binding Environmental Quality Standards (EQSs) for selected chemical pollutants (priority substances) of EU-wide concern. In the...

In the context of the Water Framework Directive, the use of effect-based tools can be foreseen for the elaboration and implementation of monitoring programmes and could be used to support the assessment of water quality and provide a link between chemical and ecological assessments. The main aim of this technical report is to present the state of t...

The Annex contains the following topics: 1. Case Studies (14 in total) 2. Proposals to assess endocrine disruption 3. Native vs preatreated water samples and passive sampling 4. Standards/Guidances available 5. Validation and standardisation of bioassays and biomarkers 6. Factsheets for certain biomarkers and bioassays 7. Biomarkers and in vitro-a...

The use of effect-based tools has been mentioned in the context of the Water Framework Directive (WFD) in the Common Implementation Strategy (CIS) guidance no.19 (on water chemical monitoring), in the CIS guidance no. 25 (on sediment and biota monitoring), and (in relation to sediment assessment) in the CIS guidance no. 27 (on environmental quality...

Annex to main technical report on effects-based monitoring

The document has been prepared by the Joint Research Centre of the European Commission (JRC) with the contribution of experts from Member States, Regional Seas Conventions and ICES and following consultation of the Working Group on Good Environmental Status. The document should be regarded as presenting an informal consensus position on best practi...

One of the major environmental impacts of oil exploration in the Ecuadorian Amazon region is the contamination of the aquatic environment. In addition to occasional major oil spills, there are several minor sources. This study investigates aquatic toxicity due to seepage from production pits and oiled road run-off. Water and sediment samples were c...

Phototoxicity to Daphnia magna was studied on 14 polycyclic aromatic hydrocarbons (PAHs) and 22 petroleum products (ranging from diesel to crude oil). The phototoxicity ranking of pure PAHs was about the same as found in another study on fish gill cells in vitro (Toxicology 127 (1998) 143), suggesting that the relative acute phototoxicity does not...

Explosives used in ammunition have been dumped in both lakes and oceans before the potential environmental effects of these chemicals were understood. Growing environmental concern in society and in the Swedish military resulted in a project dealing with the aquatic toxicology of explosives. The aim of the present study was to assess the hazard of...

Torsviken is a small bay close to the city of Gothenburg, Sweden. Part of the bay has been used for disposal of dredged harbor sediment since the 1970s. Other potential sources of contamination are a deposit site and treatment facility for hazardous waste. The area has been classified as ecologically sensitive and is of great ornithological interes...

Sediments from 48 sites along the Swedish West Coast were sampled for determination of priority pollutants (metals, polycyclic aromatic hydrocarbons and chlorinated hydrocarbons). Toxicity to two crustaceans (Daphnia magna and Nitocra spinipes) were also determined within 2 weeks and after 12 months of storage at 4°C. Since, according to earlier st...

Some compounds, accumulated by organisms, are transformed into toxic forms when irradiated with UV light. The polycyclic aromatic hydrocarbon (PAH) fluoranthene is one such compound of environmental importance. In this study on Daphnia magna, fluoranthene toxicity increased significantly after a 2 h exposure to solar-simulating UV light, if organis...

The photoinduced toxicity of several environmental pollutants (some Polycyclic Aromatic Hydrocarbons [PAHs]) is a potential threat to aquatic organisms. To identify the cause/s of photoinduced toxicity of a sample, it is not sufficient to simply analyze the content of some known phototoxic compounds; so far too few substances of environmental conce...
