Arsenic is a ubiquitous environmental contaminant, and its toxicological impact is highly dependent on its speciation. In marine edible algae, increasingly consumed for their nutritional value, arsenosugars (As-Sugars) constitute the major arsenic forms. Despite their generally low toxicity, their uncertain long-term effects …

ABSTRACT The acquisition of reliable speciation data for dietary exposure assessment is challenged by the lack of calibration standards for arsenosugars, the predominant arsenic species in algae. This limitation hinders their accurate identification and quantification. The study investigated the retention and elution …

Arsenosugars are the predominant species of arsenic in most seaweed. The analysis of these compounds is hampered by the lack of calibration standards needed in their unambiguous identification and quantification. This affects the availability of reliable information on their potential toxicity, which …

Since humans are especially sensitive to arsenic exposure, predominantly through diet, a strict control of the most widely consumed seaweeds is mandatory. Total arsenic contents and arsenic species in twenty-five different seaweeds from five different origins were studied. Seaweeds selected, included Phaeophyta …

Obtaining reliable speciation data for evaluating dietary exposure, and increasing understanding of arsenic biochemistry in algae, are hindered by the availability of suitable standards of arsenosugars, the major species in these types of samples. Moreover, chemical syntheses of such compounds have been …
