An Integrated Approach To Assess The Impacts Of Zinc Pyrithione At Different Levels Of Biological Organization In Marine Mussels., Lorna J. Dallas, Andrew Turner, Tim P. Bean, Brett P. Lyons, Awadhesh N. Jha
An Integrated Approach To Assess The Impacts Of Zinc Pyrithione At Different Levels Of Biological Organization In Marine Mussels., Lorna J. Dallas, Andrew Turner, Tim P. Bean, Brett P. Lyons, Awadhesh N. Jha
School of Geography, Earth and Environmental Sciences
The mechanisms of sublethal toxicity of the antifouling biocide, zinc pyrithione (ZnPT), have not been well-studied. This investigation demonstrates that 14-d sublethal exposure to ZnPT (0.2 or 2 μM, alongside inorganic Zn and sea water controls) is genotoxic to mussel haemocytes but suggests that this is not caused by oxidative DNA damage as no significant induction of oxidised purines was detected by Fpg-modified comet assay. More ecologically relevant endpoints, including decreased clearance rate (CR), cessation of attachment and decreased tolerance of stress on stress (SoS), also showed significant response to ZnPT exposure. Our integrated approach was underpinned by molecular analyses …

Mobilisation Kinetics Of Hazardous Elements In Marine Plastics Subject To An Avian Physiologically-Based Extraction Test., Andrew Turner
Mobilisation Kinetics Of Hazardous Elements In Marine Plastics Subject To An Avian Physiologically-Based Extraction Test., Andrew Turner
School of Geography, Earth and Environmental Sciences
Samples of plastic collected from two beaches in southwest England (n = 185) have been analysed by XRF spectrometry for elements that are hazardous or restricted in synthetic polymers (namely, As, Ba, Br, Cd, Cr, Hg, Pb, Sb and Se). Overall, one or more restricted element was detected in 151 samples, with 15 cases exhibiting non-compliance with respect to the Restriction of Hazardous Substances (RoHS) Directive. Twelve plastics that were RoHS-non-compliant were subsequently processed into microplastic-sized fragments and subjected to an avian physiologically-based extraction test (PBET) that simulates the chemical conditions in the gizzard-proventriculus of the northern fulmar. Kinetic profiles …
Plankton As Prevailing Conditions: A Surveillance Role For Plankton Indicators Within The Marine Strategy Framework Directive, Abigail Mcquatters-Gollop, David Johns, Simon Greenstreet, Jacob Bedford
Plankton As Prevailing Conditions: A Surveillance Role For Plankton Indicators Within The Marine Strategy Framework Directive, Abigail Mcquatters-Gollop, David Johns, Simon Greenstreet, Jacob Bedford
School of Biological and Marine Sciences
The Marine Strategy Framework Directive (MSFD) uses an indicator-based approach for ecosystem assessment; indicators of the state of ecosystem components ('state indicators') are used to determine whether, or not, these ecosystem components are at ‘Good Environmental Status’ relative to prevailing oceanographic conditions. Here, it is illustrated that metrics of change in plankton communities frequently provide indications of changing prevailing oceanographic conditions. Plankton indicators can therefore provide useful diagnostic information when interpreting results and determining assessment outcomes for analyses of state indicators across the food web. They can also perform a strategic role in assessing these state indicators by influencing target …

Assessing The Impact Of Benzo[A]Pyrene With The In Vitro Fish Gut Model: An Integrated Approach For Eco-Genotoxicological Studies., Laura M. Langan, Silvia Arossa, Stewart F. Owen, Awadhesh N. Jha
School of Biological and Marine Sciences
In vitro models are emerging tools for reducing reliance on traditional toxicity tests, especially in areas where information is sparse. For studies of fish, this is especially important for extrahepatic organs, such as the intestine, which, until recently, have been largely overlooked in favour of the liver or gill. Considering the importance of dietary uptake of contaminants, the rainbow trout (Oncorhynchus mykiss) intestine-derived cell line RTgutGC was cultured, to test its suitability as a high-throughput in vitro model. Benzo[a]pyrene (B[a]P) is an important contaminant and a model polycyclic aromatic hydrocarbon (PAH). Over 48 h exposure, a range of endpoints and …

Microplastics In Different Tissues Of Fish And Prawn From The Musa Estuary, Persian Gulf., Sajjad Abbasi, Naghmeh Soltani, Behnam Keshavarzi, Farid Moore, Andrew Turner, Mina Hassanaghaei
School of Geography, Earth and Environmental Sciences
Commercially-important species of fish and a crustacean from four sites in the Musa estuary and a site in the Persian Gulf have been analysed for the presence and location of microplastics (MPs). A total of 828 MPs were detected in the guts (gastrointestinal tracts), skin, muscle, gills and liver of demersal and pelagic fish (Platycephalus indicus, Saurida tumbil, Sillago sihama, Cynoglossus abbreviatus) from all five sites and in the exoskeleton and muscle of the tiger prawn, Penaeus semisulcatus, from three sites. On an individual basis, MPs were most abundant in P. indicus (mean = 21.8) and least frequently encountered in …
