【 摘 要 】

Corals incorporatemajor and trace elements in their tissues and skeletons, acting as good proxiesfor contaminant inputs over time. This incorporation occurs by a variety ofmechanisms and depends on the bioavailability of elements. Corals are very susceptibleto metal contamination during sample collection. As such, pre-treatment proceduresneed to include a decontamination step. The high Na and Ca concentrations inthe matrix make the determination of trace metals an analytical challenge. Thepresent paper reviews all the information published on coral sample pretreatments,metal determinations in corals, and also discusses the use of coral to monitormetal contamination.
