TL;DR: It is concluded that toxicity tests of metals and other organic and inorganic compounds should be based on longer times of exposure, because zinc toxicity assessed using photosynthesis of periphyton is much affected by many biological and chemical variables.

TL;DR: The toxicity of three heavy metals on an activated sludge biomass was studied by measuring several parameters of microbiological activity and the dynamics of microbial community composition, which suggested a higher sensitivity of nitrifiers to these metals than heterotrophs.

TL;DR: The results indicate that zinc toxicity -- at higher levels -- may be connected to a strong inhibition of GR activity, and related to the pro-oxidative state found.

TL;DR: The results suggest that MT-I does not compete with essential zinc-requiring proteins and is degraded, whereas MT-III competes for zinc and exacerbates zinc deficiency.

TL;DR: It was possible to suppress the cytotoxicity of zinc by increasing the concentration of either Fe2+ or Ca2+ but not Mg2+, which suggests that a prerequisite for the toxic action of zinc is entry into cells using channels that are shared with iron or calcium.
