The Wash embayment is an important area both in terms of nature conservation (RAMSAR site and Special Protection Area) and commercial fisheries (mussels and cockles). However, during the past decade many studies, particularly those concerning assessment of shellfish stocks, bird populations and pollution impact, have highlighted possible environmental problems in the area. The objectives of this study were: i) To quantify the degree of pollution impact in the Wash by measuring the scope for growth (SFG) of mussels (Mytilus edulis) collected from nine sites:- Stiffkey, Brancaster, Hunstanton, Pandora Sand, Great Ouse - Barrier Wall, Gat Sand, Roger Sand, Witham - Tabs Head, and Holy Island. ii) To analyse the concentration of specific organic contaminants in the mussel tissues (i.e. aromatic hydrocarbons); iii) To provide a toxicological interpretation of the tissue residue data based on established relationships between tissue concentrations of aromatic hydrocarbons and the stress response SFG; iv) To extract, fractionate, and toxicity test fractions derived from tissues of Pandora Sand and Holy Island mussels; and v) To analyse the most toxic fractions by GC and GC-MS.
