ABSTRACT
Speciation studies of arsenic are of paramount importance as the toxicity of the element is strongly dependent on the chemical species. The development of reliable analytical methods for arsenic speciation will contribute to improve the knowledge about both the presence and the contents of arsenic species in a wide variety of marine samples and also will support the development of legislation for the sake of consumer health.
This chapter focuses on the occurrence of arsenic in marine biota focusing on the critical aspects to be taken into account during the analytical process to guarantee reliable results. Specific considerations for algae and seafood analysis are described.
