Abstract The total arsenic mass fraction as well the speciation were studied in four different mushroom species with inductively coupled plasma spectrometry and high-performance liquid chromatography to spectrometry, respectively. Arsenic fractions detected mushrooms covering a range from 0.3 22 mg As kg −1 dry mass. For speciation, like arsenobetaine, inorganic arsenic, or dimethylarsinic acid found, which are commonly mushrooms, but it was also proven that recently discovered novel...
Environmental context With mushroom consumption increasing worldwide, it is important to know about the concentration of different arsenic species in most commonly eaten species, especially since toxicity depends on chemical structure. No dangerous amounts highly toxic inorganic were detected studied mushrooms. It therefore safe consume fruit-bodies investigated at least with regard content.Rationale A large variety considered edible. They are often considerably distinct from each other a...
The determination of the two isomers amavadin and other V species in <italic>Amanita muscaria</italic> with HPLC-ICPMS.
The measurement of small homonuclear coupling constants is often prevented by either their size and/or overlap with other signal splittings. Here, we present a real-time method to extract such couplings without interference from splittings, resolution that beyond conventional NMR spectra. In this J-upscaled SERF experiment, removed slice-selective pure shift NMR, whereas scalar only one selected reintroduced selective refocusing. remaining are enhanced J-upscaling during interruptions the...
The NMR-spectroscopy based structure elucidation of organic molecules containing heteroatoms is often obstructed by the difficulties in determining heteroatom protonation states. Here we describe a simple but broadly applicable approach for determination states heteroatoms. Differential deuterium isotope shifts observed upon addition small amounts H2O or D2O to any solvent can be used determine
Fruit-bodies of six Thelephora species ( Fungi , Basidiomycota, Thelephoraceae ) were analyzed for their trace element concentrations. In penicillata extremely high concentrations Cd and As found, followed by highly elevated Cu Zn. The highest accumulation ability was found with a mean concentration 1.17 ± 0.37 g kg –1 (dry mass) in fruit-bodies collected from 20 unpolluted sites; the 0.878 0.242 . Furthermore, striking Se (923 28 mg one sample T. vialis S detected palmata (19.6 5.9 )....
