“…A major strength of this study was the inclusion of many populations and the ability to perform predefined subgroup analyses by sex and race/ethnicity. Differences in serum Se levels by race/ethnicity may be associated with lifestyle factors such as diet, location, and genetics, as shown in a review by Papp et al [22][23][24][25].…”

Objective: This study was aimed at evaluating the association between serum selenium (Se) levels and hypertension in United States (US) adults. Methods: Data were extracted from the United States National Health and Nutrition Examination Survey (NHANES, 2009–2018). Multivariate logistic regression and subgroup analysis were conducted to examine associations between Se and hypertension. Results: Patients with hypertension had higher serum Se levels than healthy participants (P = 0.01017). After adjustment for demographic and health behaviors, serum Se levels were significantly associated with systolic blood pressure in women (OR = 0.014; 95% CI: 0.001–0.027; P = 0.04174). Serum Se levels were significantly associated with diastolic blood pressure (DBP) in both women and men. In subgroup analysis, serum Se levels were significantly associated with higher diastolic blood pressure (P for trend <0.001). Conclusion: In summary, this analysis supports a nonlinear association between serum Se levels and the prevalence of hypertension, and higher serum Se levels were associated with higher DBP.

“…Due to its adsorption by clays and iron oxides, selenite is slightly less readily available than other forms of selenium. The oxidation state of selenium is affected by the pH of the soil (Figure 1), but the ability of clays and ferric oxide to adsorb selenium is also impacted by this property [30]. Between pH 3 and 8, there was hardly any change in the amount of selenite (Se 4+ ) that was adsorbed by Fe 2 O 3 .…”

“…tiemannite (HgSe), clausthalite (PbSe), and naumannite ((Ag, Pb) Se) contains selenium and is present in soils [7]. The soil's total selenium depends on the type of parent materials and the soil-forming processes which redistribute selenium [8]. Overall, total selenium in world soils ranges from 0.125 to 0.3 mg kg À1 and varies with the soils' nature [9].…”

Selenium (Se) is essential as well as a toxic element for humans and animals if it exceeds a certain limit. Soil selenium plays an important role through the food chain. Total selenium in world soils ranges from 0.125 to 0.3 mg kg−1 and varies with the soils’ nature. High and low selenium in soils also poses serious environmental and health risks. However, in addition to selenium\'s overall quantity in soil, selenium reactivity, and bioavailability also depend on its chemical structure. The amount of available selenium in the soil varies depending on its oxidation state since selenium species include selenide (Se2−), elemental selenium (Se0), selenite (Seo32−), selenate (Seo42−). The pH, soil texture, amount of organic matter, and the presence of competing ions are the four most significant soil characteristics that affect Se availability. Similarly, selenium uptake and accumulation are influenced by the crop type whether it is an accumulator or not. The selenium environmental and health risk assessment is necessary to evaluate in soils with high selenium contents and crops with higher selenium uptake. Whereas in areas where selenium deficiency is observed or vulnerable to selenium, deficiency needs to be supplemented through Se inputs. The selenium deficiency and toxicity areas should be monitored carefully from a health perspective.

Soil has high spatial variability. Under the change of water level, soil nutrient element content and enzyme activity do not show regular changes. Therefore, the effects of biological metabolism on soil nutrient element content and enzyme activity in the adult stage of Metasequoia glyptostroboides were proposed. The characteristics of the soil were extracted, the irreversibility, accumulation, concealment and refractory rationality of the nutrient element content in the soil were expounded. According to the soil characteristics, the relationship between the nutrient element content and enzyme activity in the soil was analysed. The pH value, organic matter, lead and manganese contents of the soil were determined, and the effects of biological metabolism of M. glyptostroboides on the nutrient content and enzyme activity of the soil were studied.The results showed that the content of nutrient elements in soil was relatively high after the biological metabolism of M. glyptostroboides in the adult stage, the infiltration rate 2 of seedling soil changed, and the effects of different Metasequoia glyptostroboides roots on soil enzyme activities were different.
