The European Green Deal’s ambition for zero pollution requires development of highly sensitive techniques to detect ultra-low amounts pollutants and determine their isotope ratios, where mass spectrometry is a key method. project bridges the traceability gap between activity measurements – particularly estimation bias establishes new tools pollutant tracing. SI-traceable reference materials measurement procedures are being developed that significantly reduce uncertainty detection limits,...
Radioactive anthropogenic pollution has raised concerns about the present and future environmental status of semienclosed Baltic Sea. We here study distribution inventory radioactive 129I in water depth profiles collected from 16 sites August 2006 19 April 2007 Proper related Kattegat Skagerrak basins. The results reveal considerable differences concentration terms spatial temporal variability expose relatively high concentrations deep waters. Variability 127I, stable natural isotope iodine,...
The metabolism of flupenthixol decanoate administered in viscoleo® by intramuscular or subcutaneous injection has been studied thin‐layer chromatographic techniques after extraction urine, faeces and organs from dogs rats. Since only minute amounts the compound itself were detected a high hydrolytic activity blood was demonstrated vitro experiments, it concluded that is hydrolyzed organism. thus formed found to be metabolized sulphoxidation dealkylation side chain following same pattern as...
Indoor radon and its decay products are the primary sources of population's exposure to background ionizing radiation. Radon one leading causes lung cancer, with a higher cancer risk for smokers due synergistic effects cigarette smoking. A total 459 year-long measurements in 257 detached semi-detached residential homes southwest south Greenland were carried out, dose assessment adults was performed. The annual arithmetic geometric means indoor concentrations 10.5 ± 0.2 Bq m-3 8.0 2.3 Nuuk,...
Polonium-210 (210Po) is a radionuclide sentinel as it bioaccumulates in marine organisms, thereby being the main contributor to committed dietary doses seafood consumers. Although and mammals are an important part of traditional Inuit diet, there general lack information on 210Po concentrations Greenlandic food chain leading human consumer. Here, we determine background edible parts different organisms from Greenland provide dose assessment. Blue mussels (Mytilus edulis), organs ringed seal...
Occurrence of anthropogenic 129I in seawater has provided invaluable information about water circulation and exchange rates, but results on species (iodide iodate) are limited only available for surface water. We here present the first extensive 127I samples depth profiles, which were collected August 2006 April 2007 Skagerrak, Kattegat, Baltic Proper. The expose ≤10% annual reduction iodate as is transported from English Channel along Dutch coast German Bight into Skagerrak Kattegat. also...

Radon-222 (222Rn) and its decay products are the primary sources of a population's exposure to background ionizing radiation. Radon leading cause lung cancer for non-smokers second after smoking smokers. A community-driven long-term radon survey was completed in 232 residential homes different subdivisions Whitehorse, capital Yukon, during heating season from November April 2016-2017 2017-2018. concentrations were measured living rooms bedrooms on ground floors. The arithmetic geometric...
The metabolism of orally administered Lu 5‐003 has been studied in the rat, dog and man. Urine faeces were by thin layer chromatography basic acidic extracts. metabolic degradation was shown to proceed partly sulphoxidation demethylation followed deamination side chain. Seven metabolites found. pattern same three species investigated. A semiquantitative determination showed demethylated metabolite be main excretion products faeces, while more water soluble sulphoxides these compounds...
During exposure to high altitude the red cell metabolism was stimulated. An increase in phosphofructokinase reaction occurred secondary elevated blood pH. triosephosphate pool PFK stimulation and a relative inhibition of GAPDH reaction, which due decrease concentration inorganic phosphate. The low phosphate levels both cells plasma were consequence shift from extracellular fluid other body during hyperventilation. forward stimulated when accompanied by moderate degree physical exercise.

Eleven factors were obtained by factor analysing the CPRS results from a longitudinal treatment process study in chronic schizophrenics during maintenance phase. Such may give more reliable information than single item. Two factors--"anxiety-depression-asthenia" and "psychotic" (psychotic schizophrenic symptoms signs)--nonpsychotic rating of anxiety depressive as well definite psychotic-schizophrenic symptoms, respectively--demonstrated special value for clinical work, i.e. being relevant...
Abstract The kinetics of nortriptyline in four patients were investigated before and during treatment with perphenazine (24–36 mg/day) by administering 57 mg hydrochloride as an intravenous infusion evaluating the resulting plasma concentration data according to a two compartment open model. In all increased biological half‐life well decreased systemic clearance rate metabolism found perphenazine‐period, thus confirming inhibitory effect on earlier studies. Some interaction distribution...
During acute exposure to high altitude (2 hours) the red cell metabolism is altered. A pH-induced increase in phosphofructokinase activity together with a decrease level of monophosphoglycerates are most prominent features changes. Despite pH, 2,3-diphos-phoglycerate not altered, probably because reduction concentration inorganic phosphate. Besides 2,3-DPG neither ATP, ADP, lactate, or pyruvate levels changed significantly during this duration. The results interpreted as being due combined...
