differences. If BAC should be developed for fi sh species which prefere more polluted habitats (coast), it<br />

could be helpful to use an species independent BAC for fi sh instead. SGIMC 2010 proposed a joint BAC<br />

for three fi sh species cod dab and haddock. A BAC value applicable for more marine fi sh species would be<br />

helpful regarding inter-species evaluation <strong>of</strong> monitoring data.<br />

Even if PAH metabolites are only a marker <strong>of</strong> exposure, high levels <strong>of</strong> metabolites can be linked to deleterious<br />

effects in fi sh. EACs have been be identifi ed using results from toxicological experiments linking oil<br />

exposure and PAH metabolites in fi sh with DNA adducts and fi tness data (Morton et al. 2010; Skadsheim<br />

et al. 2004; Skadsheim et al. 2009), where <strong>the</strong> latter serves as <strong>the</strong> effect quantity for <strong>the</strong> calculation <strong>of</strong> <strong>the</strong><br />

EAC presented in Table 3.10. EAC are available for some fi sh species only at <strong>the</strong> moment. More investigations<br />

are needed to calculate proper EAC values for Baltic fi sh species. EACs cannot be easily transferred to<br />

o<strong>the</strong>r species because <strong>the</strong>y may differ in sensitivity to PAH effects.<br />

two PAH metabolites, different fi sh species and methods. Data partly taken from WKIMC 2009 and<br />
