Arsenosugars extracted from algae: Behavior study using dispersive solid-phase extraction

Alba Morales-Rodríguez, Berta Vilarrúbies, Yemna Badar, Pablo Eiriz et autres

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 …

Arsenosugar extracted from algae: Assessment of countercurrent chromatography for isolation

Alba Morales-Rodríguez, A. Sahuquillo, Cristina Minguillón, José Fermı́n López-Sánchez et autres

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 …

Survey of arsenic content in edible seaweeds and their health risk assessment

Yanli Yu, Alba Morales-Rodríguez, Guangming Zhou, D. Barrón et autres

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 …

Arsenosugar extracted from algae: Isolation by anionic exchange solid‐phase extraction

Alba Morales-Rodríguez, Miquel Pérez-López, Elle Puigpelat, A. Sahuquillo et autres

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 …
