Potential effects of sea level rise on metal mobility and availability in estuarine soils and sediments Universiteit Gent
Dioxins, furans and dioxin-like PCBs in sediment samples and suspended particulate matter from the Scheldt Estuary and the North Sea Coast: comparison of CALUX concentration levels in historical and recent samples Vrije Universiteit Brussel
BACKGROUND: The Scheldt estuary is historically a highly polluted river system. While several studies have focused on contamination with metals, pesticides, Polycyclic Aromatic Hydrocarbons (PAHs) and marker PolyChlorinated Biphenyls (PCBs), no data are available concerning past contamination by dioxin-like compounds.
OBJECTIVES: The objective of this study is to determine spatial and time trends of PolyChlorinated Dibenzo-p-Dioxins and ...

Changing extreme sea levels along European coasts KU Leuven
Extreme sea levels at European coasts and their changes over the twentieth and twenty-first centuries are considered, including a method to analyze extreme sea levels and to assess their changes in a consistent way at different sites. The approach is based on using a combination of statistical tools and dynamical modelling as well as observational data and scenarios for potential future developments. The analysis is made for both time series of ...
Vibrio lentus as a probiotic candidate lowers glucocorticoid levels in gnotobiotic sea bass larvae Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Plasma cortisol is the classical parameter to assess acute stress in vertebrates, while in fish larvae whole body cortisol is used. Immuno assays are commonly adopted for cortisol determination in a pool of fish larvae. At present no method exists for quantification of a full glucocorticoid profile of a single fish larva providing a detailed snap-shot of hypothalamic-pituitary-interrenal (HPI) axis activity. To date, a substantial amount of ...
Levels and profiles of persistent organic pollutants in several tissues of harbour porpoises (**Phocoena phocoena**) from the Black Sea Universiteit Antwerpen
Harbour porpoises (Phocoena phocoena) are one of three cetacean species inhabiting the Black Sea. PCBs (polychlorinated biphenyls) and PBDEs (polybrominated diphenyl ethers) are two types of lipophilic compounds which are banned in Europe since the 1970s (for PCBs) and 2004 (for PBDEs). Despite this, they are still present in the environment and can cause toxic effects in wildlife, including marine mammals. Recently, attention has been drawn ...
In Situ Mortality Experiments with Juvenile Sea Bass (Dicentrarchus labrax) in Relation to Impulsive Sound Levels Caused by Pile Driving of Windmill Foundations Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Impact assessments of offshore wind farm installations and operations on the marine fauna are performed in many countries. Yet, only limited quantitative data on the physiological impact of impulsive sounds on (juvenile) fishes during pile driving of offshore wind farm foundations are available. Our current knowledge on fish injury and mortality due to pile driving is mainly based on laboratory experiments, in which high-intensity pile driving ...
Determination of tetrodotoxin (TTX) levels in various tissues of the silver cheeked puffer fish (Lagocephalus sceleratus (Gmelin, 1789)) in Northern Cyprus Sea (Eastern Mediterranean) KU Leuven
Lagocephalus sceleratus from the family Tetraodontidae, which is originated from the Red Sea, started to migrate to Mediterranean waters after the opening of the Suez Channel in 1869. Since they do not have any predators in the Mediterranean Sea, their population increased in number very fast. Different tissues of L. sceleratus have tetrodotoxin (TTX). TTX is a non-protein, heat resistant molecule which binds to voltage-gated sodium channels of ...
Higher trophic levels in the southern North Sea “TROPHOS” Instituut voor Natuur- en Bosonderzoek
TROPHOS is a co-operation between five Belgian institutes (RUG-Marine Biology, KULeuven-Aquatic Ecology, Institute of Nature Conservation, MUMM and VLIZ) and one Dutch institute (NIOO-CEMO) and aims at a better understanding of processes structuring the higher trophic levels in the North Sea. As we will not ignore the link between ecosystem functioning and aquatic biodiversity, our results will also serve in aspects of sustainable management for ...
Levels and distribution of polybrominated diphenyl ethers and organochlorine compounds in sea turtles from Japan Universiteit Antwerpen
Three species of sea turtles (green. hawksbill and loggerhead turtles) stranded along the coasts or caught (by-catch) around Ishigaki Island and Kochi, Japan were collected between 1998 and 2006 and analyzed for six organohalogen compounds viz., PBDEs, PCBs, DDTs, CHLs, HCHs and HCB. The present study is the first and foremost to report the occurrence of organohalogen compounds in the sea turtles from Japan. Among the compounds analyzed, ...
