Marine Mammal Ecotoxicology

Exposure to persistent organic pollutants such has been shown to cause reproductive failure in wild seals and other aquatic mammal species and endocrine disruptive toxic mechanisms are believed to be involved. Impaired reproductive capacity exacerbates the ability of marine mammal populations to recover from other threats such as climate change, over-fishing, hunting and habitat destruction.

The project aims to study receptor-level interaction of pollutants with sex hormone receptors in marine mammal reproductive tissues and to undertake population bio-monitoring of pollutant exposure and sex hormone concentrations in wild seals. This work will be in collaboration with the RSPCA (Royal Society for the Prevention of Cruelty to Animals) in the Wildlife Rehabilitation Hospitals.

Gera Troisi - Dr Gera M. Troisi is a lecturer in the School of Engineering and Design at Brunel University London since 2001, delivering undergraduate and postgraduate modules on Medical Device Risk Management, Environmental Risk Assessment and Life Cycle Analysis on Biomedical, Sustainable and General Engineering courses and has supervised several postgraduate students to successful completion of PhD-doctoral degrees, MPhil and MRes. She is a Chartered Toxicologist-Ecotoxicologist (UK & Europe) and is a member of the Risk Assessment Committee (RAC) of the European Chemicals Agency (ECHA) which advises on the classification, labelling and restriction of chemicals within the European Union under the REACH and CLP regulations. Her principal research interests are environmental toxicology of humans and wildlife (ecotoxicology, endocrine disruption, biomonitoring, biosensors, environmental analysis); Risk Assessment and Aquaculture. She has over 30 research publications covering these disciplines. She has coordinated a number of research and consultancy projects related to environmental toxicology funded by both non-governmental (RSPCA, WWF, Care for the Wild, Greenpeace) and governmental agencies (DEFRA) and industry (Safeway, Slimming Systems Ltd and Lufthansa-Hawker Pacific Aerospace). Before beginning her career in academia, Dr Troisi worked as a Senior Scientific Officer in the Medical Research Council (MRC) Institute for Environment & Health. She holds a doctorate degree in Environmental Toxicology from the University of Essex and is a member of the British and European Toxicology Societies. Dr Troisi offers the following consultancy services: Medical Device Risk Management; Environmental Risk Assessment; Health Risk Assessment; Ecological Risk Assessment; Life Cycle Analysis; Environmental Impact Assessment; Health and Ecological Impacts; Laboratory analysis of environmental pollutants (polychlorinated biphenyls (PCBs) and metabolites (Methyl sulphones), pesticides, heavy metals and polyaromatic hydrocarbons (PAHs); emergent pollutants (brominated flame retardants)) drugs and biologically-active compounds (steroid hormones).
