“…Therefore, the potential risk of selenosis for local residents may be a matter of concern. Qin et al [17] reported that the daily Se intake of the residents from three other high-Se areas, Anlejing, Huabei and Yutangba, located in Enshi City, was approximately 2144 µg day −1 , which was greatly higher than that from Shadi in this study. The possible reason was that the foods were collected from different sites, and the distribution of Se in soils was significantly uneven.…”

“…Although no human Se toxicity has been reported in recent years, the symptoms of animal Se toxicity have been observed, including hoof and hair loss [16]. Recently, Qin and collaborators reported that the daily Se intake of the residents from three high-Se areas, Anlejing, Huabei and Yutangba located in Enshi City, was approximately 2144 µg day −1 , posing a potential chronic selenosis risk for local residents [17]. Selenium concentrations in blood, urine, hair and nail tissues can be used as bio-indicators to evaluate Se accumulation in the human body.…”

Enshi is a high selenium (Se) region in Hubei, China, where human selenosis was observed between 1958 and 1963. This study investigated the daily dietary Se intake of residents in Shadi, a town located 72 km northeast of Enshi City, to assess the risk of human selenosis in the high Se area. Foods consumed typically by the local residents and their hair samples were analyzed for total Se concentration. Concentrations of Se in different diet categories were as follows: cereals: 0.96 ± 0.90 mg kg−1 DW in rice and 0.43 ± 0.55 mg kg−1 DW in corn; tuber: 0.28 ± 0.56 mg kg−1 in potato and 0.36 ± 0.12 mg kg−1 in sweet potato; vegetables: ranging from 0.23 ± 1.00 mg kg−1 in carrot to 1.57 ± 1.06 mg kg−1 in kidney bean; animal proteins: 1.99 ± 1.11 mg kg−1 in chicken and egg. Based on the food Se concentrations and the daily per-capita consumption, the estimated daily Se intake in Shadi was 550 ± 307 µg per capita. Moreover, the Se concentrations in the hairs of local adult residents were 3.13 ± 1.91 mg kg−1 (n = 122) and 2.21 ± 1.14 mg kg−1 (n = 122) for females and males, respectively, suggesting that females might be exposed to higher levels of Se from daily cooking. Although there was no human selenosis occurrence in recent years, the high level of the daily Se intake suggested that the potential risk of selenosis for local residents, especially females, might be a matter of concern.

“…Zhao et al (2012) reported that the spatial patterns of the heavy metal concentrations and soil pH indicated that the areas with the highest human health risk did not directly coincide with the areas of highest heavy metal concentrations but instead with the areas of lower soil pH. Qin et al (2013) observed that the concentration of Se in rice plants was associated with the soil fraction bound to SOM, suggesting that SOM controls Se uptake by rice and thus increases hazards to human health. Pelfrêne et al (2011) concluded that the inclusion of bioavailability analyses during health risk assessment (fraction of pollutant that is soluble in the gastrointestinal environment and potentially available for absorption) would provide a more realistic assessment of heavy metal exposure than traditional measurements.…”

Abstract. Soil quality (SQ) assessment has long been a challenging issue, since soils present high variability in properties and functions. This paper aims to increase the understanding of SQ through the review of SQ assessments in different scenarios providing evidence about the interrelationship between SQ, land use and human health. There is a general consensus that there is a need to develop methods to assess and monitor SQ for assuring sustainable land use with no prejudicial effects on human health. This review points out the importance of adopting indicators of different nature (physical, chemical and biological) to achieve a holistic image of SQ. Most authors use single indicators to assess SQ and its relationship with land uses -soil organic carbon and pH being the most used indicators. The use of nitrogen and nutrient content has resulted sensitive for agricultural and forest systems, together with physical properties such as texture, bulk density, available water and aggregate stability. These physical indicators have also been widely used to assess SQ after land use changes. The use of biological indicators is less generalized, with microbial biomass and enzyme activities being the most selected indicators. Although most authors assess SQ using independent indicators, it is preferable to combine some of them into models to create a soil quality index (SQI), since it provides integrated information about soil processes and functioning. The majority of revised articles used the same methodology to establish an SQI, based on scoring and weighting of different soil indicators, selected by means of multivariate analyses. The use of multiple linear regressions has been successfully used for forest land use. Urban soil quality has been poorly assessed, with a lack of adoption of SQIs. In addition, SQ assessments where human health indicators or exposure pathways are incorporated are practically inexistent. Thus, further efforts should be carried out to establish new methodologies to assess soil quality not only in terms of sustainability, productivity and ecosystem quality but also human health. Additionally, new challenges arise with the use and integration of stable isotopic, genomic, proteomic and spectroscopic data into SQIs.

“…The recommended daily allowance is 50–200 μg per day for adults . If the daily intake of selenium exceeds this range, the body would exhibit a variety of functional disorders such as heart disease or hypothyroidism . Moreover, it is found that selenium bioavailability and toxicity in the human body are largely dependent on the species in which it occurs.…”

A highly sensitive method was developed for the simultaneous separation and determination of organic and inorganic selenium species in rice by ion-pairing reversed-phase chromatography combined with inductively coupled plasma tandem mass spectrometry. To achieve a good separation of these species, a comparison between anion-exchange chromatography and ion-pairing reversed-phase chromatography was performed. The results indicated that ion-pairing reversed-phase chromatography was more suitable due to better separation and higher sensitivity for all analytes. In this case, a StableBond C18 column proved to be more robust or to have a better resolution than other C18 columns, when 0.5 mM tetrabutylammonium hydroxide and 10 mM ammonium acetate at pH 5.5 were used as the mobile phase. Moreover, an excellent sensitivity was obtained in terms of interferences by means of tandem mass spectrometry in the hydrogen mode. The detection limits were 0.02-0.12 μg/L, and recoveries of five selenium species were 75-114%, with relative standard deviations ≤ 9.4%. This method was successfully applied to the analysis of rice samples. Compared with previous studies, the proposed method not only gave comparable results when used for measuring selenium-enriched rice, but it can provide greater sensitivity for the detection of low concentrations of selenium species in rice.
