There have been contentions on the appropriate description of a number of metals that cause ecotoxicological effects, the definition of heavy-metals inherently does not depict toxic effects. What's the way forward?
the word heavy metals implies that the metals in question are above a threshold atomic weight, typically incorporating all transition metals of the periodic table, yet members of the actinide and lathinide series although heavier than transition metals are not considered as 'heavy metals'.
the word 'metals' as suggested by Borja does not readily capture or depict the toxico-chemical criterion that highlight the metals of concern.
