“…Seaweed can be used for marine sediment remediation (Cheney, Rajic, Sly, Meric, & Sheahan, ) indicating that the uptake of PCBs occurs. Ulva rigida placed into a PCB‐contaminated harbor contained, after 1 day, 3.9 mg PCBs/kg (Cheney et al., ). Ulva rigida can take up PCBs rapidly and can concentrate them (Cheney, ).…”

Seaweed is a source of protein that can help overcome the anticipated challenges of a growing world population and the current challenges for finding alternatives for animal proteins in the Western diet. Thus far, data on the safety of seaweed for feed and food purposes in the Western world are scattered. This study aimed to review the available knowledge on the presence of food safety hazards in seaweed, including factors influencing their presence, and to prioritize the hazards that may pose a risk to human health. Given current knowledge from the literature, data from the Rapid Alert System for Food and Feed, and results from a stakeholder survey, 22 food safety hazards were ranked into major (4), moderate (5), and minor (13) hazards. Arsenic, cadmium, iodine, and Salmonella were identified as major hazards. Hazards, where data gaps exist, should be carefully assessed. These include pesticide residues, dioxins and polychlorinated biphenyls, brominated flame retardants, polycyclic aromatic hydrocarbons, pharmaceuticals, marine biotoxins, allergens, micro‐ and nanoplastics, other pathogenic bacteria, norovirus, and hepatitis E virus. It is recommended to collect more data on these hazards in future studies. Many factors can affect the presence of hazards including seaweed type, physiology, season, harvest and cultivation environment, geography including the location of cultivation, alongside further processing. Moreover, when seaweed is cultivated near industrialized or anthropogenic activities, these activities may negatively influence water quality, which can increase the likelihood of hazards in seaweed. Results of the ranking prioritized hazards can be used to prioritize monitoring programs and adjusted given future additional knowledge covering the data gaps.

“…A major caveat is a general lack of information in the literature with respect to seaweed and chemical risk assessment, with implications for food safety (Banach et al, 2020). Indeed, there is evidence that seaweed can take up pesticides and other compounds very efficiently (Lorenzo et al, 2012, Cheney et al, 2014, Anacleto et al, 2017, but there is a lack of uptake, bioaccumulation, and effects studies under laboratory conditions for seaweed species.…”

“…Las algas representan un biomaterial muy abundante que ha sido empleado exitosamente en tareas de remediación (con biomasa viva o muerta). Así lo demuestran numerosos trabajos que evalúan el uso de distintas macroalgas en la remoción de uranio, cobre, cadmio, arsénico, zinc e incluso compuestos orgánicos (Cheney et al 2014;Anacleto et al 2017;Bagda et al 2017; Deniz y Karabulut 2017; Flores-Chaparro et al 2017, 2018Vieira et al 2017;Poo et al 2018). A nivel local, muchos trabajos evidencian las potencialidades de las macroalgas argentinas en la remoción de distintos contaminantes del agua.…”

En la extensa costa argentina se encuentran numerosas especies de macroalgas de importancia a nivel mundial. En el presente trabajo se debaten los estudios más relevantes publicados hasta la fecha sobre los usos de las algas marinas y se mencionan las investigaciones argentinas con el objetivo de evaluar el estado de conocimiento del recurso. La revisión muestra que en nuestro país se publicaron numerosos trabajos que evidencian el valor de las algas en la alimentación humana y animal, en la producción de compuestos químicos beneficiosos para la salud y en aplicaciones ambientales. Sin embargo, ciertas áreas tales como el desarrollo de biocombustibles y el uso en el campo de la agricultura revelan la necesidad de profundizar en la investigación. Se concluye que las algas marinas argentinas, además de tener numerosas aplicaciones, son un recurso con gran potencial de explotación comercial para beneficio de las poblaciones costeras.
