“…Low Se levels in about 67% of agricultural soils of China are responsible for a wide-spread Se deficiency in the Chinese population [15][16]. A study in Algeria showed that the concentration of Se in wheat was a reflection of Se levels in regional soils [17]. Low Se concentrations in wheat in Belgium were also associated with low Se levels of Belgian soils [18].…”

Selenium (Se) exhibits a "double-edged" behavior in animal and human nutrition. It is a micronutrient required in low concentrations by animals and humans, but toxic at high concentrations. Selenium deficiency has been associated with cancer and other health problems. Selenium requirements are commonly met through soils and plants such as wheat, rice, vegetables and maize in many countries. Selenium concentration in the soil generally ranges from 0.01-2.0 mg kg-1 but seleniferous soils usually contain more than 5 mg kg-1. Seleniferous soils have been reported in Ireland, China, India and USA. Weathering of parent rocks and atmospheric deposition of volcanic plumes are natural processes increasing Se levels in the environment. Anthropogenic sources of Se include irrigation, fertilizer use, sewage sludge and farmyard manure applications, coal combustion and crude oil processing, mining, smelting and waste incineration. Mobility of Se in the soil-plant system largely depends on its speciation and bioavailability in soil which is controlled by pH and redox potential. Plant uptake of Se varies with plant species and Se bioavailability in the soil. The uptake, translocation, transformation, metabolism, and functions of Se within the plant are further discussed in the paper. The release of Se in soils and subsequent uptake by plants has implications for meeting Se requirements in animals and humans.

“…In humans, two diseases have been associated with severe endemic Se deficiency including fatal congestive Environ Chem Lett cardiomyopathy known as Keshan disease and osteoarthropathy known as Kashin-Beck disease (Yao et al 2011;Beladel et al 2013). It is reported that very small quantities of Se are required through dietary sources to maintain good health in both humans and animals.…”

“…During the last two decades, researchers in different countries have been interested in Se content in frequently consumed food (Tahtat et al 2003;Dundar and Altundag 2004;Sirichakwal et al 2005;Choi et al 2009;Beladel et al 2013). Selenium, an essential trace mineral for human health, has many physiological functions.…”

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.

Selenium‐Enriched Breads and Their Benefits in Human Nutrition and Health as Affected by Agronomic, Milling, and Baking Factors

Bread is among the three top foods that provide most of the dietary selenium (Se) for most of the world population. Selenomethionine present in flour and bread is the major organic moiety (>65%). The Se concentration assayed in wheat kernels is mainly affected by agronomic factors such as soil fertility. The dry milling of wheat to produce refined flour and the technology to produce leavened breads also greatly affect Se concentration and bioavailability. The supranutritional intakes of inorganic and mainly organic Se have long been linked to the prevention of cancer, oxidative stress, and cardiovascular diseases. This review provides an overview of the different Se sources and agronomic, milling, and processing factors that affect Se concentration and bioavailability in yeast‐leavened and sourdough breads and the nutritional and health implications that have been documented by food, medical, and nutrition scientists.
