This article introduces the EU Horizon 2020 research project GRACE (Integrated oil spill response actions and environmental effects), which focuses on a holistic approach towards investigating understanding hazardous impact of spills impacts benefits suite marine technologies in cold climate ice-infested areas North Atlantic Baltic Sea. The methods considered include mechanical collection water below ice, situ burning, use chemical dispersants, natural biodegradation, combinations these. naturally chemically dispersed oil, residues resulting from non-collected fish, invertebrates (e.g. mussels, crustaceans) macro-algae are assessed by using highly sensitive biomarker methods, specific for rapid detection effects pollution biota developed. By observing, monitoring predicting movements sea through novel online sensors vessels, fixed platforms including gliders so-called SmartBuoys together with real-time data transfer into operational systems that help to improve information location spill, situational awareness can be improved.

Toward an integrated framework for assessing micropollutants in marine mammals: Challenges, progress, and opportunities

Critical Reviews in Environmental Science and Technology, Journal Year: 2020, Volume and Issue: 51(23), P. 2824 - 2871

As apex predators, marine mammals play a key role in maintaining community structure and functioning ecosystems. Hence, decline mammal populations may have negative effects on the ecosystem function services. The discharge of anthropogenic chemicals particles (micropollutants) into environment threatens health mammals. Traditional approaches for assessing impact micropollutants are limited by complexity (e.g., low concentrations, unknown contaminants, transformation products, mixture effect) complex physiology, life history, multiple stressors, logistical challenges) environment. Recently developed (bio)analytical tools that can integrate chemical biological assessment such as non-target suspect screening, direct effect analysis, multiomics metabolomics, lipidomics, proteomics, transcriptomics) offer critical insights (i) risks 'known' 'unknown' mammals, (ii) link between exposure population effects, (iii) identification priority micropollutants. This review highlights challenges current progress risk posed to A tired integrated chemical-ecological-biological framework from research practices is offered effective micropollutant

Monitoring of emerging contaminants of concern in the aquatic environment: a review of studies showing the application of effect-based measures

Analytical Methods, Journal Year: 2021, Volume and Issue: 13(43), P. 5120 - 5143

Water scarcity is increasingly a global cause of concern mainly due to widespread changes in climate conditions and increased consumptive water use driven by the exponential increase population growth. In addition, pollution fresh sources rising production consumption pharmaceuticals organic chemicals will further exacerbate this concern. Although surface contamination individual often at very low concentration, for instance are designed be efficacious concentrations, creating genuine their presence freshwater sources. Furthermore, additive impact multiple compounds may result toxic or other biological effects that otherwise not induced chemicals. Globally, different legislative frameworks have led pre-emptive efforts which aim ensure good ecological status.

Hazard screening of contaminants of emerging concern (CECs) in Sweden’s three largest lakes and their associated rivers

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 453, P. 131376 - 131376

Published: April 12, 2023

Persistent, mobile, and toxic (PMT) substances have recently garnered increased attention by environmental researchers, the water sector protection agencies. In this study, acute chronic species sensitivity distributions (SSDs) were retrieved from literature data for previously quantified contaminants of emerging concern (CECs) in Swedish surface waters (n = 92) risk quotients (RQ) calculated. To better understand characteristics detected CECs non-urban lake sites 71), these compounds checked against established criteria potentially PMs (PM(T)s) occurrence aquatic environment, respectively. For with missing SSDs 15 [acute], n 41 [chronic]), ecotoxicity extracted eight taxonomic groups, if sufficient ≥ 3), derived. The newly developed then used an hazard assessment (EHA) investigated rivers lakes. rivers, 8 had RQ> 1 at least one location, 20 posed a moderate (0.01 < RQ 1). total, 21 71 already been identified as PM(T)/vPvM substances. Our study shows importance studying field large spatial scale to reveal potential hazards far source areas.
