Research Abstract

In this study, we analyzed 6 species of macroalgae collected at 19 locations along Osaka Bay for 13 metal elements by ICP-MS in the purpose of usage of metal element compositions of algae as a bio-indicator of marine water pollution. As a result, macro algae collected along Honshu Island around Osaka City are enriched in various toxic metals compared to those along Awaji Island with less contamination of toxic metals. This strongly suggests that the chemical composition of macroalgae reflects the degree of marine pollution and can be a useful bio-indicator.
