Sodium selenate
Human toxicity Elemental selenium metal has a relatively low order of toxicity. Acute poisoning with selenium and its salts are rare, however, in excessive amount toxic and even fatal action was documented. Normal whole blood selenium levels in adults range from 0.085 to 0.13 mg/l [2]. All selenium salts can produce toxicity by ingestion, inhalation, and percutaneous absorption, although specif...
متن کامل4-Benzylpyridinium hydrogen selenate
The structure of the title salt, C(12)H(12)N(+)·HSeO(4) (-), consists of infinite parallel two-dimensional planes built of 4-benzyl-pyridinium and hydrogen selenate ions that are mutually connected by strong O-H⋯O and N-H⋯O hydrogen bonds. There are no contacts other than normal van der Waals inter-actions between the layers.
متن کاملCharacterization of a selenate-resistant Arabidopsis mutant. Root growth as a potential target for selenate toxicity.
Screening an Arabidopsis (Arabidopsis thaliana) T-DNA mutant library for selenate resistance enabled us to isolate a selenate-resistant mutant line (sel1-11). Molecular and genetic characterization showed that the mutant contained a lesion in the SULTR1;2 gene that encodes a high affinity root sulfate transporter. We showed that SULTR1;2 is the only gene among 13 mutated genes of the Arabidopsi...
متن کامل2-Amino-5-nitropyridinium hydrogen selenate
There are two cations and two anions in the asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-). In the crystal, there are two independent chains of HSeO(4) (-) anions running along the a axis, linked by O-H⋯O hydrogen bonds. Ribbons of cations linked by N-H⋯O hydrogen bonds run along the b-axis direction, and are further hydrogen bonded to the anions by N-H⋯O and C-H⋯O link...
