Rice has the predilection to take up arsenic in form of methylated (o-As) and inorganic species (i-As). Plants defend themselves using i-As efflux systems production phytochelatins (PCs) complex i-As. Our study focused on identification quantification by HPLC-ICP-MS/ESI-MS, relating them several variables linked As exposure. GSH, 11 PCs, As–PC complexes from roots six rice cultivars (Italica Carolina, Dom Sofid, 9524, Kitrana 508, YRL-1, Lemont) exposed low high levels were compared with...
Multi-element analysis of honey samples was carried out with the aim developing a reliable method tracing origin honey. Forty-two chemical elements were determined (Al, Cu, Pb, Zn, Mn, Cd, Tl, Co, Ni, Rb, Ba, Be, Bi, U, V, Fe, Pt, Pd, Te, Hf, Mo, Sn, Sb, P, La, Mg, I, Sm, Tb, Dy, Sd, Th, Pr, Nd, Tm, Yb, Lu, Gd, Ho, Er, Ce, Cr) by inductively coupled plasma mass spectrometry (ICP-MS). Then, three machine learning tools for classification and two attribute selection applied in order to prove...
Throughout the world, biomonitoring has become standard for assessing exposure of individuals to toxic elements as well responding serious environmental public health problems. However, extensive surveys require rapid and simple analytical methods. Thus, a high-throughput method is proposed determination arsenic (As), cadmium (Cd), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), selenium (Se) in blood samples by using inductively coupled plasma-mass spectrometry (ICP-MS). Prior...
Selenium deficiency has been a worldwide concern because it can pose risk to human health. nanoparticles (SeNPs) are in general less toxic and more bioavailable than ionic Se and, therefore, their use for biofortification of food crops attracted attention. Rice is staple consumed by half the world's population. Indeed, studies on SeNPs' impacts oxidative stress antioxidant responses rice seedlings scarce. Herein, effect different concentrations SeNPs growth, enzyme activity, reactive oxygen...
Anthropogenic activities and improper uses of phosphate fertilizers have led to an increase in cadmium concentrations agricultural soils. Brassinosteroids are steroid hormones that rapidly assimilated metabolised with beneficial roles physiological biochemical processes plants. Our aim was ascertain whether exogenous treatment 24-epibrassinolide (EBR) can mitigate the Cd toxicity, this substance reduce accumulation plant tissues. Furthermore, dose response EBR determined following exposure...
l-Cystine functionalized δ-FeOOH nanoparticles (Cys-δ-FeOOH) were prepared by a cheap and straightforward method for using as an adsorbent of Hg(II) in aqueous solution. X-ray diffraction (XRD), attenuated total reflectance infrared spectroscopy (ATR-IR), Raman confirmed that Cys-δ-FeOOH was successfully synthesized. with 14 nm crystal size, 34 m2 g−1 surface area, 9 pore size produced. The functionalization the cysteine decreases point zero charge iron oxyhydroxide from 8.4 to 5.7...
There are several international regulations regarding trace elements. The use of ICP-MS for their determination is usually a difficult task, especially when Hg one the target
The soybean is a legume that widely cultivated in many countries due to the high levels of protein and oil contained its seed, used for human animal nutrition. However, salinity affects more than 800 million hectares worldwide, limiting global agricultural production. aim this research was evaluate structural behaviour roots stems under progressive salt stress, detailing possible anatomical modifications these organs plants during stress. were randomized into five treatments (0, 50, 100, 150...
