Cadmium (Cd) is a highly toxic heavy metal particularly susceptible to mobilization by anthropogenic and natural processes. The volcanic nature of oceanic islands in the Macaronesia geographical region such as the Azores archipelago, located near the Mid-Atlantic Ridge, is reflected in deep-sea and shallow-water hydrothermal activities that release heavy metals such as Cd to seawater, affecting marine organisms and integrating...

Shallow water hydrothermal vents can be compared to polluted places due to high concentrations of heavy metals, and are thus good models for bioaccumulation studies. The present study intended to estimate the time of exposure required for the accumulation of certain elements to stabilize in specimens of Cystoseira abies‐marina , to be used as a reference in future work. Cystoseira abies‐marina intertidal specimens were transpl...
