“…Se is also involved in membrane protection and has an anti-cancer action. In addition, Se plays an important role in the antioxidant protection of cells, and as a component of different enzymes such as glutathione peroxidase and thioredoxin reductase (Combs andGrey, 1998, Birringer et al, 2002;Ferrarese et al, 2012).…”

SUMMARY:The biofortification of food crops for human consumption is a direct strategy increasing dietary intake of selenium (Se). The aim of this study was to evaluate the possibility of increasing the Se content of extra virgin olive oil (EVOO) by spraying the olive tree canopy with sodium selenate and the effect of the increase in Se on the chemical properties and sensory characteristics of the EVOO. Se treatments were up to 50 times more effective in enhancing Se content in the EVOO compared with the untreated controls. Se concentration in all the EVOO samples can be considered adequate and useful for providing the human diet with the correct dose of Se. Se-enriched EVOO showed a significant increase in pigment and phenol content. Also, Se treatment does not produce negative effects on fruit characteristics or the sensory quality of EVOO. KEYWORDS: Biofortification; Chemical parameters; Extra virgin olive oil (EVOO); Fruit characteristics; Nutraceutical value; Selenium (Se); Sensory qualityRESUMEN: Aumento del contenido de selenio en aceites de oliva virgen extra: implicaciones cuantitativas y cualitativas. La biofortificación de cultivos alimenticios para el consumo humano es una estrategia directa para aumentar la ingesta de selenio (Se) en la dieta. El objetivo de este estudio fue evaluar la posibilidad de aumentar el contenido de Se en aceites de oliva virgen extra (AOVE) pulverizando la copa de los olivos con selenato de sodio y el efecto del aumento en el contenido de Se en las propiedades químicas y características sensoriales del AOVE. Los tratamientos con Se fueron muy eficaces consiguiendo aumentar el contenido de Se en el AOVE hasta 50 veces más en comparación con los controles no tratados. La concentración de Se en todas las muestras EVOO puede considerarse adecuada y útil para proporcionar a la dieta humana con la dosis correcta de Se. EVOO-Se enriquecido mostró un aumento significativo en pigmentos y contenido de fenoles. Además, el tratamiento de Se no implica efectos negativos sobre caracteristicas frutales ni sobre la calidad sensorial de AOVE.

“…The recommended dietary allowance in the USA is 55 lg Se day -1 , and the reference nutrient intake in the UK is 60-75 lg Se day -1 (White and Broadley 2005). Sources: data compiled from Petry (2011) In general, food fortification with Se is a delicate task due to a very narrow safety margin between toxicity and deficiency (Ferrarese et al 2012). Therefore, biofortification using Se fertilizers must be performed under very strict conditions, since an over-accumulation in the edible parts might be toxic for consumers (Ferrarese et al 2012).…”

“…High Se concentration in soils may not induce phytotoxic symptoms but reduces the yield of crops. The addition of Se directly in the nutrient solution allows producing enriched leafy vegetables avoiding excessive concentration in the edible parts (Malorgio et al 2009;Ferrarese et al 2012). It is reported that Se statutory maximum annual loading rates (0.15 kg ha -1 year -1 ) over a 10-year period for agricultural soils in the UK (DoE 1996) and statutory maximum cumulative metal loading rates (100 kg ha -1 ) for agricultural soils in the USA (USEPA 2000) and critical soil concentrations (11 kg ha -1 ) considered to be phytotoxic (calculating on basis a soil bulk density of 1.2 g cm -3 and a depth of 10 cm; Kabata-Pendias 2011), as reviewed by White et al (2012).…”

“…The properties of produced soil are determined by ancillary factors such as the position of the site on the landscape and the vegetation present. Climate is generally the most important variable and can determine the soil kind or preclude the occurrence of some kinds of soils (Eswaran et al 2012). There are several studies concerning the relation between soils and human health (Abrahams 2002(Abrahams , 2006Smith et al 2009;White and Brown 2010;White et al 2012;Brevik and Burgess 2013;Bañuelos et al 2014).…”

Selenium in soils under climate change, implication for human health

et al. 2014

Global climate changes can alter the suitable geographical range of different crops, leading to possible changes in cropping pattern and its extent in some regions. For example, temperature changes can interact very closely with changes in availability of water and soil nutrients, and crop growth cycle. The consequences of the biophysical impacts of climate changes will be influenced by the human responses to these impacts. There is a strong link between soils and human health, and these soils per se are controlled by climate changes. The human health is very close to both selenium (Se) element and climate changes. It is estimated that about 37-40 % of the total Se emissions to the atmosphere are due to the anthropogenic activities.Those anthropogenic activities, which are sources of Se, include coal and oil combustion, mining activities, the utilization of rock phosphates as a fertilizer and the application of sewage sludge to agricultural land. It was thought that selenium was a toxicant for a long time due to inadequate analytical data. In the recent past, Se has become very important in environmental biogeochemistry because of its influence on human health. Although Se is an essential nutrient for animals and humans, it is also toxic at high doses. Furthermore, the range between Se deficiency, lower than 40 lg day -1 , and toxicity, higher than 400 lg day -1 , is narrow. Selenium deficiency has been linked to several human diseases including multiple sclerosis, muscular dystrophy, heart disease, immune system, cancer and reproductive disorders. On the other hand, Se toxicity can lead to hair and nail loss and disruption of the nervous and digestive systems in animals and humans. Despite the obvious connections between Se element and human health under climate changes, there has not been a great amount of research done in this area. So, more and more studies should be carried out to enhance and protect human health. Therefore, this article reviews the biological and economic dimensions of the effects of Se element on human health under climate changes.

BACKGROUND Biofortification of vegetables is an important innovation technique in the horticultural sector. Vegetables can be a vector of different minor elements that have beneficial effects on human health. Selenium (Se) is an important element for human nutrition and plays a significant role in defence mechanisms. The aim of this work was to investigate the effect of Se in the nutrient solutions on the crop biofortification ability, yield, and quality parameters of four baby leafy vegetables destined to the minimally processed industry. Experiments were performed on lamb's lettuce, lettuce, wild rocket, and spinach. These crops were cultivated in the floating systems with nutrient solution enriched with 0, 2.6, 3.9, and 5.2 μmol L−1 Se provided as sodium selenate. RESULTS At harvest, Se concentrations, yield, nitrate concentration, sugars, and some mineral elements were measured. Data collected and analyses showed that yield, nitrate, sucrose, and reducing sugars were not affected by Se treatments, even if varied among species. Se concentrations linearly increased in leaves of different species by increasing the Se concentration in the nutrient solution. Rocket was the species with the highest accumulation ability and reached a concentration of 11 μg g−1 fresh weight Se in plants grown with 5.2 μmol L−1 Se. CONCLUSION A floating system with Se‐enriched nutrient solution is an optimal controlled growing biofortification system for leafy vegetables. The accumulation ability decreased in different species in the order wild rocket, spinach, lettuce, and lamb's lettuce, highlighting a crop‐dependent behaviour and their attitude to biofortification. © 2023 The Authors.
