Fig. 2

Biomarker responses of Corbicula sp. after 10 weeks of exposure to PACnative and PACWWTP. a GST activity in units (U), b catalase activity in units (U), and c MDA conjugate formation (extent of lipid oxidation). The bars represent means (n = 6) with standard deviations. The horizontal line shows the respective biomarker response from before the exposure start. Bars below the line indicate a lower biomarker response and bars above the line a higher biomarker response as compared to the initial biomarker response, respectively. Asterisks give significant differences between the control and the treatments; *: 0.01 ≤ p ≤ 0.05; for catalase, the difference between control and initial biomarker response was also significant
