Abstract

Coral reefs are increasingly threatened by human activities (e.g., sewage discharge and industrial effluents). Composition of coral skeleton is expected to quantitatively record the change in marine environments in which skeletal calcium carbonate is precipitated. Recently, trace elements, particularly heavy metals, in the skeleton of massive and annually banded corals have been successfully used as a proxy of marine pollution at regional and local scale. Critical problems, however, exist due to lack of a well-established method for analyzing trace elements in coral skeleton. Large range in reported values for heavy metal concentrations in coral skeleton could be attributed to differences in pretreatment procedures of skeletal materials rather than the real extent of marine pollution. In this review, we summarize recent progress of studies on the topics and key factors for the further application of coral proxies in order to reconstruct the history of marine pollution.
