Use of macroalgae to biomonitor pollutants in coastal waters: Optimization of the methodology

Abstract Although native macroalgae have been used for biomonitoring purposes since the 1950s, a standardized protocol that would enable widespread implementation of the technique has not yet been developed. The aim of this review study, in which 445 articles were consulted, was to evaluate the monitoring methods applied in coastal environments worldwide and to assess the degree of standardization of the techniques used. Finally, on the basis of the conclusions reached, we propose a standardized protocol for implementing the method.
