Abstract

Humanity and industrialization have led to ecosystems, in all their matrices, being compromised in terms of pollution generated by different metals. Among them we find mercury and lead, both correspond to metals highly dangerous for all ecosystems and their trophic chains. In this review we will look at the dangers of these metals and the ways in which they can be removed, ranging from more traditional processes to adsorption processes with materials derived from natural sources and how they can be an effective source of heavy metal removal.
