The 1986 Chernobyl nuclear disaster initiated a series of catastrophic events resulting in long-term and widespread environmental contamination. We characterize the genetic structure 302 dogs representing three free-roaming dog populations living within power plant itself, as well those 15 to 45 kilometers from site. Genome-wide profiles Chernobyl, purebred free-breeding dogs, worldwide reveal that individuals City are genetically distinct, with former displaying increased intrapopulation...
A contamination with the ubiquitous radioactive fission product 137Cs cannot be assigned per se to its source. We used environmental samples varying levels from various parts of world establish their characteristic 135Cs/137Cs isotope ratios and thereby allow distinction. The included biological materials Chernobyl Fukushima, historic ashed human lung tissue 1960s Austria, trinitite Trinity Test Site, USA. After chemical separation gas reaction shifts inside a triple quadrupole ICP mass...
The “Chernobyl nuclear disaster” released huge amounts of radionuclides, which are still detectable in plants and sediments today. Bryophytes (mosses) primitive land lacking roots protective cuticles therefore readily accumulate multiple contaminants, including metals radionuclides. This study quantifies 137Cs 241Am moss samples from the cooling pond power plant, surrounding woodland city Prypiat. Activity concentrations up to 297 Bq/g (137Cs) 0.43 (241Am) were found. contents significantly...
Ceasium-137 and 90Sr are major artificial radionuclides that have been released into the environment. Soil-to-plant transfer of is an important route to food contamination. The radionuclide activity concentrations in crops must be quantitatively predicted for estimating internal radiation doses from ingestion. In this study, soil potato samples were collected three study sites contaminated with different sources 137Cs 90Sr: Aomori Prefecture (global fallout) two accidental release areas...
The 1986 disaster at the Chornobyl Nuclear Power Plant transformed surrounding region into most radioactive landscape known on planet. Whether or not this sudden environmental shift selected for species, even individuals within a that are naturally more resistant to mutagen exposure remains an open question. In study, we collected, cultured, and cryopreserved 298 wild nematode isolates from areas varying in radioactivity Exclusion Zone. We sequenced assembled genomes de novo 20 Oscheius...
Radiometric or mass spectrometric analysis of the long-lived fission product 107Pd is notoriously difficult. We developed and optimized a chemical separation protocol for minute amounts radiopalladium with subsequent measurement by inductively coupled plasma triple quadrupole spectrometry propane as collision gas. This allows detection limits <2 ng 107Pd/kg, which makes method suitable environmental samples low levels 107Pd. For testing this method, sample sediment from Chernobyl cooling...
Due to the large number of nuclear power plants around globe and growing threat radioactive accidents, a complex assessment biological consequences Chornobyl disaster is relevant issue. Study mutagenic activity prolonged chronic action radionuclide pollution soil in Exclusion Zone long after accident will allow us identify current level they pose human genome can reveal specific cytogenic markers environmental pollution. For this purpose, we germinated seeds wheat soft winter varieties...
ABSTRACT The 1986 disaster at the Chornobyl Nuclear Power Plant transformed surrounding region into most radioactive landscape known on planet. Questions remain regarding whether this sudden environmental shift selected for species, or even individuals within a that are naturally more resistant to radiation exposure. We collected, cultured, and cryopreserved 298 wild nematodes isolates from areas varying in radioactivity Exclusion Zone. sequenced assembled genomes de novo 20 Oschieus tipulae...
