“…Under certain conditions, NPs can be transported essentially unchanged to different compartments of the organism, where they will be stored and function as ion stores. Such possibilities were suggested by their shortterm presence in blood and accumulation in internal organs [39,43]. This behavior, in particular, can be specific to Ag NPs.…”

Silver has been known since ancient times on account of its pronounced antiseptic properties. Currently, its antibacterial, antiviral, and fungicidal properties are highly desired in the food and cosmetic industries, in medicine, and pharmacology. Silver exhibits toxic effects not only on pathogenic organisms but also on healthy cells. Over the past 20 years, nanosilver, a new form of silver, has been introduced in various areas of industry. The transition to the nanoscale form results in the revision of standard approaches to items, including those based on this element, and the emergence of such a novel research area as nanosafety. In this review, we address the history of using different forms of silver, the mechanisms of its interaction with living cells, toxic properties, biokinetic parameters, capability for accumulation in different organs, effects on cognitive functions, and the clinically known argyrosis condition. Relevant publications are critically analyzed and conclusions are drawn. The broader incorporation of such a weakly biophilic element as silver in the biosphere and ecosphere calls for our understanding of biochemical processes underlying the interaction of this element, in its different forms, with living cells and multicellular organisms.

“…However, plants have different absorption capacities for selenium. Generally, plants can be divided into three categories: super-cumulative, cumulative and non-cumulative [12][13]. At the same time, the absorption of selenium by plants also depends on many conditions, such as environmental conditions, soil and plants, but the most important influencing factors are the existence form of selenium in the soil and the concentration of selenium [14][15].…”

At present, as a high-end snack, macadamia nuts have a variety of beneficial effects on human health, such as preventing cardiovascular disease, preventing diabetes, maintaining weight, etc., its rich nutritional value and health care functions have attracted more and more attention. In this paper, four different treatments were performed on the same type of macadamia through field experiments, and they were sprayed with different concentrations of exogenous selenium fertilizer. Based on the selenium content, the effects of macadamia nuts on selenium absorption and conversion were studied. . The test results showed that when the selenium fertilizer was diluted to 100-fold concentration, the selenium content of the sample plant increased by 107.4%, and the yield increased by 23.8%. When the selenium fertilizer was diluted to 200-fold concentration, the selenium content of the sample plant increased by 100.0%, and the yield It increased by 25.7%. When the selenium fertilizer was diluted to 300 times concentration, the selenium content of the sample plants increased by 55.6%, but the yield decreased by 1.0%, indicating that the appropriate concentration of selenium fertilizer has a certain effect on improving the selenium content and efficiency. Comparing the four treatments, it can be found that exogenous selenium can increase the yield of macadamia nuts, and its output will increase first and then decrease with the increase of the dilution factor and concentration, and the best dilution effect is 200 times.

“…The amounts of silver accumulated in brains and their parts were studied by not so wide-spread technique for this purpose as NAA. It required several years to develop the approach of the best tracking, detecting and precise measuring of the amounts of each kind of nanoparticles, for instance, silver, in biological tissues [22,44,45]. However, the principle of NAA is fairly simple.…”
