The concentrations of twenty metal elements in seawater and in plankton around the recently erupted submarine volcano Tagoro just South of the island El Hierro (Canary Islands, Spain) were investigated in order to assess their potential hazard to the marine environment. Samples of the seawater and the plankton were collected from 2013 to 2016 during the Vulcano and Vulcana monitoring cruises, using a rosette with Niskin bottles and a WP2 net (200 m mesh size). Significantly higher concentrations of many metals were found in both the seawater and the plankton around the volcano compared to reference stations. The amount of metals emitted by the volcano appeared to be decreasing over the years following the eruption in 2011-2012, which greatly reduced the biomass of the plankton living in the area of influence of the volcano. In 2013 the metal concentrations found in the plankton living in the area were very high, but a decrease in concentrations was found towards 2016. Around ...
