“…Trace metal elements are widely presented in living tissue ( Karavoltsos et al., 2020 ). Although some of them are also beneficial for human functional metabolism at low doses, excessive retention of any of toxic trace elements in the environment imposes threats to human health ( Huang et al., 2008 ; Liang et al., 2020 ).…”

“…As the color-grained wheat could provide a good dietary source of anthocyanin pigments (Abdel-Aal et al, 2016), and its production is sustainable. In this regard, the purple-grained wheat would be highly desirable for Se biofortification Trace metal elements are widely presented in living tissue (Karavoltsos et al, 2020).

Selenium (Se) is an essential micronutrient for human health. Deficiency and suboptimality of Se in human populations are a potential health risk. The reduction of such health risk by biofortification of crops, particularly in wheat has drawn much attention, especially for color-grained wheat as it is rich in anthocyanins and can be used as a major source of antioxidants in diet. Herein, a two-year field study on the purple-grained wheat cultivar (202w17) and common wheat cultivar (Shannong 129) was conducted with soil application (SeS) and foliar spray (SeF) of selenium. Results showed that the SeS increased shoot dry weight and grain yield. Both SeS and SeF enhanced the concentration of organic Se, but the higher concentration of organic Se in the grain of two cultivars was observed in SeF in comparison with SeS. The concentration of organic Se in the grain of 202w17 treated with SeF was approximately 1.5-fold of that in Shannong 129 with SeF. The analysis of Se accumulation in different parts of the plant revealed that 202w17 accumulated more Se in shoots and grain than Shannong 129, and 202w17 had also higher levels of total protein, total free amino acids and anthocyanin in grain than Shannong 129. In addition, SeF significantly increased the concentrations of zinc (Zn), calcium (Ca), magnesium (Mg) in both cultivars, but decreased the concentration of chromium (Cr), cadmium (Cd) and lead (Pd), which phenomenon was more significant in 202w17. Our results indicate that SeS increases plant growth, leading to higher grain yield in two cultivars tested. The purple-grained wheat (202w17) could accumulate more Se in grain and have a higher concentration of orgainic Se in grain than the common wheat (Shannong 129).

Levoglucosan has been widely used to quantitatively assess biomass burning’s contribution to ambient aerosols, but previous such assessments have not accounted for levoglucosan’s degradation in the atmosphere. We develop the first global simulation of atmospheric levoglucosan, explicitly accounting for its chemical degradation, to evaluate the impacts on levoglucosan’s use in quantitative aerosol source apportionment. Levoglucosan is emitted into the atmosphere from the burning of plant matter in open fires (1.7 Tg yr–1) and as biofuels (2.1 Tg yr–1). Sinks of atmospheric levoglucosan include aqueous-phase oxidation (2.9 Tg yr–1), heterogeneous oxidation (0.16 Tg yr–1), gas-phase oxidation (1.4 × 10–4 Tg yr–1), and dry and wet deposition (0.27 and 0.43 Tg yr –1). The global atmospheric burden of levoglucosan is 19 Gg with a lifetime of 1.8 days. Observations show a sharp decline in levoglucosan’s concentrations and its relative abundance to organic carbon aerosol (OC) and particulate K+ from near-source to remote sites. We show that such features can only be reproduced when levoglucosan’s chemical degradation is included in the model. Using model results, we develop statistical parametrizations to account for the atmospheric degradation in levoglucosan measurements, improving their use for quantitative aerosol source apportionment.

Introdução: Fortes evidências demonstram associação entre o alto consumo de sódio e o desenvolvimento de doenças cardiovasculares, hipertensão arterial, entre outras complicações metabólicas. A literatura é escassa, no entanto, em relação ao estudo da composição do sal de cozinha, um ingrediente amplamente utilizado pela população. Assim é de extrema importância conhecer a composição dos sais que se utilizam com frequência na culinária. Objetivo: Analisar a composição química de diferentes sais de cozinha: refinado/comum, rosa do Himalaia, marinho e light. Paralelamente, a precificação e os rótulos foram também analisados, a fim de relacioná-los com as análises químicas. Método: A determinação de minerais foi realizada pelo método 3050-B rev.02/SMEWW 3111-B e a quantificação de metais totais foi feita por espectrometria de absorção atômica com chama. Resultado: Observaram-se diferenças significativas na quantidade de minerais encontrada em sais da mesma natureza, provenientes de diferentes marcas. Os resultados mostraram ainda que o sal rosa do Himalaia apresentou maiores teores de cálcio, ferro, magnésio e sódio em comparação aos demais (p<0.05). Analisando precificação e informações de rotulagem, identificaram-se preços significativamente diferentes entre os produtos, além da ausência de informações sobre sua composição química. Conclusão: Os resultados demonstram que há diferenças na composição mineral de sais de cozinha e indicam a necessidade de identificar a composição desses nutrientes nos rótulos, possibilitando que a população possa escolher o melhor tipo de sal e/ou marca através do rótulo alimentar, levando em consideração o custo-benefício.
