Copper in liver and plasma – Exp.1.

<p>(<b>A</b>) Copper liver burden (expressed as µg/g wet weight) in fish exposed to 0 (Ctrls), 10 and 100 µg/L copper for 9 days. Values are means ± SE (<i>n</i> = 10/12). The asterisk denotes statistically significant difference from the control value (<i>P</i><0.05, Tukey <i>t</i>-test) (<b>B1–2</b>) Plasma copper levels (µg/ml) in fish exposed to 0, 10 and 100 µg/L copper and sampled either before (B1) or after (B2) the salinity transition. Values are means ± SE (<i>n</i> = 4/7). The asterisk denotes statistically significant difference from the control value post switch (<i>P</i><0.05, Tukey <i>t</i>-test). Solid horizontal lines represent median values and dashed lines represent mean values.
