Abstract
Sprat (Sprattus sprattus) larvae and mixed zooplankton were collected from sites in the southern North Sea across three transects running north, north-west and west from the Elbe and Weser estuaries (Germany). Sprat larval sub-cellular fractions (13500 g supernatants) were assayed for the antixoxidant enzymes catalase (EC 1.11.1.6) and superoxide dismutase (SOD; EC 1.15.1.1), and levels of polychlorobiphenyls (PCBs), p,p′-DDE and polycyclic aromatic hydrocarbons (PAHs) were determined in the mixed zooplankton (fish larval diet). Higher levels (p<0.05) of SOD and catalase activities were observed at sites closest to estuaries corresponding to sites with the highest levels (p<0.05) of total PCBs and p,p′-DDE. Antioxidant enzymes activities decreased in samples collected from sites further from the estuaries across a northern and north-western transect; however this was not observed across a western transect. Larval antioxidant enzyme activities are discussed in relation to potential processes affecting them including plankton contaminant level distributions.

Sprat larval sub-cellular fractions (13500 g supernatants) were assayed for the antixoxidant enzymes catalase (EC 1.11.1.6) and superoxide dismutase (SOD; EC 1.15.1.1), and levels of polychlorobiphenyls (PCBs), p,p′-DDE and polycyclic aromatic hydrocarbons (PAHs) were determined in the mixed zooplankton (fish larval diet). Higher levels (p<0.05) of SOD and catalase activities were observed at sites closest to estuaries corresponding to sites with the highest levels (p<0.05) of total PCBs and p,p′-DDE. Antioxidant enzymes activities decreased in samples collected from sites further from the estuaries across a northern and north-western transect; however this was not observed across a western transect. Larval antioxidant enzyme activities are discussed in relation to potential processes affecting them including plankton contaminant level distributions.</abstract><note type="content">Fig. 1: Sampling stations for S. sprattus larvae and mixed zooplankton collected on the FS Victor Hensen (27 May–1 June and 17–23 June 1991) in the southern North Sea.</note><note type="content">Fig. 2: Specific activities of superoxide dismutase (SOD; (□) SOD units mg−1 protein) and catalase ((■)μmol min mg−1 protein) in Sprattus sprattus larvae sampled at stations (St.) across: (a) northern transect, (b) north western transect, (c) western transect in the southern North Sea. ∗ p<0.05 vs site 51; †p<0.05 vs sites 33; §p<0.05 vs site 45; ‡p<0.05 vs other stations of Fig. 2(c).
