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 />
