Накратко на български

Арсенолипидите в кафявите водорасли от Исландия се анализират, за да се разбере как се образуват тези химични съединения. Това е важно, защото някои форми на арсена са токсични и carcinogenic, което влияе върху безопасността на водораслите като храна.

Overcoming barriers in estimating toxicity of arsenic species in seaweed

SilhouetteOfSeaweed contributes to consumer’s safety by overcoming barriers in estimating toxicity of arsenic in seaweed. The ocean covers 71% of the planet and for future sustainability and long term food security for a growing global population the need for using the ocean for food, e.g. seaweed, is increasing. Seaweed contains high amounts of arsenic, which can be found in different chemical forms (often called arsenic species) in the seaweed and one of these forms/species are arsenolipids. Arsenic can be toxic to humans and animals and is known to be carcinogenic, however, the toxicity depends on the arsenic species. The majority of the arsenic in seaweed is in the chemical form of arsenosugars, which are not acutely toxic, while other arsenic species are generally present in much lower concentrations. Recently the first data regarding the toxicity of arsenolipids has shown that they are as toxic as the most toxic chemical form of arsenic, the inorganic arsenic. The production of arsenosugars most likely takes place within the seaweed itself, however, it is unclear where and how the arsenolipids are produced. There is a considerable lack of data on arsenolipids in seaweed products for human consumption. More research and information on arsenolipids are urgently needed to address and ensure the safety of seaweed used in food products. Currently, only few research groups worldwide work on arsenolipids partly due to difficulties associated with the measurements of these compounds. The MCSA project SilhouetteOfSeaweed had two main scientific objectives. Firstly, to produce arsenolipid seaweed profiles in 4 different species of brown algae in 3 locations during 3 seasons in Iceland. Secondly, to use statistical evaluation and comparison of environmental conditions to e.g. make it possible to identify whether the seaweed could be harvested at specific conditions where the amount of toxic arsenic is at its lowest and thus minimises the risk of seaweed for human consumption.

Цел на проекта

SilhouetteOfSeaweed will contribute to consumer’s safety by overcoming barriers in estimating toxicity of arsenic species in seaweed. The ocean covers 71% of the planet and for future sustainability the need for looking at using the ocean for food, e.g. seaweed, is increasing. Seaweed contains high amounts of arsenic, including arsenolipids (AsLp). Recently the first data on AsLp toxicity have elucidated that they are as toxic as the most toxic arsenic, the inorganic arsenic (iAs). There is a lack of data on AsLps in seaweed products for human consumption. Safety of seaweed must be addressed and more studies and information on AsLps are urgently needed. Currently, only few research groups worldwide work on AsLps, partly due to difficulties associated with the measurements of these compounds. SilhouetteOfSeaweed will expand this expertise in Europe by establishing necessary facilities at the host Matís to accommodate AsLp measurements. Matís has the capacity to reach this goal together with the experienced researcher and in co-operation with a European partner organisation with expertise in AsLp measurements. SilhouetteOfSeaweed will have two main scientific impacts. Firstly, it will produce AsLp seaweed profiles in 4 different species of brown algae in 3 locations during 3 seasons in Iceland. This information will contribute to the necessary risk assessment needed for algae used for human consumption. Secondly, statistical evaluation and comparison of environmental conditions will make it possible to identify whether the seaweed could be harvested at specific conditions where the amount of toxic arsenic is at its lowest. These data are essential for SMEs entering the European market with their seaweed products. Moreover the project will impact the career development of the experienced researcher who will gain a wide range of scientific and transferable skills that are relevant to establish a long-term independent leading career in the field of science.
