TLDR
The toxicity of many redox-active compounds and their copper complexes appears to be due, at least partly, to the intracellular generation of hydrogen peroxide during oxidation of these compounds, an effect exacerbated by the ability of copper to inhibit catalase.About:

Performance Characteristics of Diffusion Gradients in Thin Films for the in Situ Measurement of Trace Metals in Aqueous Solution
Hao Zhang,William Davison +1 more
TL;DR: In this article, diffusive gradients in thin films (DGT) is used for quantitatively measuring labile species in aqueous systems by ensuring that transport of metal ions to an exchange resin is solely by free diffusion through a membrane, of known thickness, Δg.

Mechanism of toxicity of ionic copper and copper complexes to algae
TL;DR: The mechanism of toxicity of ionic copper and copper complexes to growth, photosynthesis, respiration, ATP levels and mitochondrial electron-transport chain-activity in two marine diatoms, Nitzschia closterium and Asterionella glacialis Castracane, was investigated and copper-ethylxanthogenate was exceptional amongst the copper complexes.

Effects of copper and cadmium on heavy metal polluted waterbody restoration by duckweed (Lemna minor).
TL;DR: Investigating changes in the contents of soluble protein and photosynthetic pigments as well as the activity of antioxidant enzymes caused by copper sulfate and cadmium dichloride during concentration-dependent exposure to metal salt demonstrated that exposure to high concentration heavy metals could result the disintegration of antioxidant system in duckweed.
