Integrated chemical and biological assessment of contaminant impacts in selected european coastal and offshore marine areas

Autores: Hylland, Ketil; Robinson, Craig D.; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Mattew J.
This paper reports a full assessment of results from ICON, an international workshop on marine integrated contaminant monitoring, encompassing different matrices (sediment, fish, mussels, gastropods), areas (Iceland, North Sea, Baltic, Wadden Sea, Seine estuary and the western Mediterranean) and endpoints (chemical analyses, biological effects).  ICON has demonstrated the use of a framework for integrated contaminant assessment on European coastal and offshore areas. The assessment showed that chemical contamination did not always correspond with biological effects, indicating that both are required. The framework can be used to develop assessments for EU directives. If a 95% target were to be used as a regional indicator of MSFD GES, Iceland and offshore...

DNA damage in dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) from European seas
Provedor de dados: 5
Autores: Hylland, Ketil; Skei, Bjorn Borge; Brunborg, Gunnar; Lang, Thomas; Gubbins, Matthew J.; Le Goff, Jeremie; Burgeot, Thierry.
Dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) were collected from coastal and offshore locations in the Baltic (dab only), North Sea (haddock from one location only) and Iceland. Blood was analysed for DNA strand breaks using the comet assay and liver samples for DNA adduct concentrations. DNA strand breaks were at background levels in dab from the two Iceland locations and from the Dogger Bank. The highest levels were observed in dab from the Firth of Forth, Ekofisk and the German Bight. Hepatic DNA adducts in dab were highest at Ekofisk, in the Baltic and Dogger Bank, below detection limit in dab from Iceland and low in dab from the Firth of Forth and German Bight. There was large variation in DNA strand breaks between locations and...

Cryptosporidium, a zoonotic pathogen, is able to infect a wide range of hosts including wild and domestic animals, and humans. Although it is well known that some parasites are both fish pathogens and recognized agents of zoonosis with a public health impact, little information is available concerning the prevalence of Cryptosporidium in wild aquatic environments. To evaluate the prevalence of Cryptosporidium spp. in commercially important edible marine fish in different European seas (English channel, North sea, Bay of Biscay, Celtic sea and Mediterranean sea), 1,853 specimens were collected as part of two surveys. Nested PCR followed by sequence analysis at the 18S rRNA gene locus was used to identify Cryptosporidium spp. The overall prevalence of...

Quantitative morphological variation in Sagitta setosa Müller, 1847 (Chaetognatha) and two closely related taxa
Provedor de dados: 16
Autores: Peijnenburg, Katja T.C.A.; Pierrot-Bults, Annelies C.
This paper reviews the quantitative morphological variation published for Sagitta setosa Müller, 1847 and two other species described within the S. serosa-complex, viz., S. euxina Moltschanoff, 1909 from the Black Sea, and S. batava Biersteker &amp; Van der Spoel, 1966 from the Scheldt Estuary (Netherlands). Data on total (body) length, caudal length, numbers of teeth and hooks, ovary length, and dimensions of fins are compared between these three taxa. Additionally, samples from the North Sea, Mediterranean, and Black Sea are compared to look for geographic differences. Specimens from the Mediterranean were smallest with relatively long caudal segments, and few teeth and hooks, whereas specimens from the Black Sea were largest with relatively short caudal...
