Chitosan–zeolite composite as a low-cost and efficient material in the removal of caesium synthetic liquid organic radioactive waste solutions.

We report population-based rates of congenital anomalies in the Rivne province of Ukraine. The rates are significantly higher in the northern half of Rivne, a region called Polissia which is polluted by Chornobyl ionizing radiation. In this region of forested wet-lands, also called Prypiat Marshlands, the soils are distinct from those in non-Polissia. The soils in Polissia transfer caesium more...

We have synthesized the mono-ruthenium substituted Keggin-type silicotungstate [SiW(11)O(39)Ru(III)(H(2)O)](5-) (1a) by reaction of the mono-lacunary silicotungstate precursor [SiW(11)O(39)](8-) with Ru(acac)(3) under hydrothermal conditions and isolated as the caesium salt Cs(5)[SiW(11)O(39)Ru(III)(H(2)O)] (1). The DMSO-coordinated complex [SiW(11)O(39)Ru(III)(DMSO)](5-) (2a) was prepared by r...

The spatial distribution and seasonal variations of atmospheric iodine (I), selenium (Se) caesium (Cs) depositions remain unclear this precludes adequate inputs for biogeochemical models. We quantified total concentrations fluxes these elements in rainfalls from 27 monitoring sites France with contrasted climatic conditions; monthly measurements were taken over one year (starting 2016/09). Sinc...

In yeast cells, of which the intracellular potassium had been partly replaced by rubidium or caesium, the intracellular ion distribution was studied by means of energy-dispersive X-ray microanalysis. The cells were rapidly frozen and thin sections were cut at low temperature on a cryo-ultramicrotome without the use of a trough liquid. By this dry cryosectioning procedure, complete retention of ...

BACKGROUND After the Chernobyl accident in 1986, as much as 5% of the released caesium-137 was deposited in Sweden due to a heavy rainfall 2 days after the event. A study of increased incidence of malignancies was initiated after the accident. METHODS The cohort included 1,137,106 inhabitants who were 0-60 years old in 1986 and lived in 8 counties of Sweden with the highest fallout of caesium...

The ethyl oxazole-4-carboxylate was directly and regioselectively alkenylated, benzylated and alkylated with alkenyl-, benzyl-, allyl- and alkyl halides in the presence of catalytic amounts of palladium acetate with caesium carbonate using Buchwald's JohnPhos ligand.
