Radioactive isotopes originating from the damaged Fukushima nuclear reactor in Japan following earthquake and tsunami March 2011 were found resident marine animals migratory Pacific bluefin tuna (PBFT). Publication of this information resulted a worldwide response that caused public anxiety concern, although PBFT captured off California August contained activity concentrations below those naturally occurring radionuclides. To link radioactivity to possible health impairments, we calculated...
After the Chernobyl nuclear power plant accident in 1986, contaminated soils, vegetation from Red Forest and other radioactive debris were buried within trenches. In this area, trench T22 has long been a pilot site for study of radionuclide migration soil. Here, we used 454 pyrosequencing 16S rRNA genes to obtain comprehensive view bacterial archaeal diversity soils collected inside vicinity investigate impact waste disposal on prokaryotic communities. A remarkably high abundance Chloroflexi...
Abstract We reconstructed the radiological dose for birds observed at 300 census sites in 50-km northwest area affected by accident Fukushima Daiichi nuclear power plant over 2011–2014. Substituting ambient rate measured points (from 0.16 to 31 μGy h −1 ) with adult of each species 0.3 97 ), we confirmed that overall bird abundance decreased increasing total doses. This relationship was directly consistent exposure levels found literature induce physiological disturbances birds. Among 57...
Uranium (U) presents a unique challenge for ecological risk assessments (ERA) because it induces both chemical and radiological toxicity, the relative importance of these two toxicities differs among various U source terms (i.e., natural, enriched, depleted). We present method conversion between concentrations microg L(-1)) dose rates (microGy h(-1)) defined set reference organisms, apply this to previously derived benchmarks determine extent which ensure protection, respectively, in...
Due to the increasing interest in environmental protection against ionizing radiation on international scene, need for operational tools radiological risk assessment is becoming critical. Within this framework, paper puts forward a fast and user-friendly computerized method allow transformation from exposure (expressed Bq per unit of mass or volume) dose (i.e., energy deposited organism, expressed Gy) received any radionuclide by non-human species, time "concentration" source. The...
Under the International Atomic Energy Agency (IAEA)'s EMRAS (Environmental Modelling for Radiation Safety) programme, activity concentrations of 60Co, 90Sr, 137Cs and 3H in Perch Lake at Canada Limited's Chalk River Laboratories site were predicted, freshwater primary producers, invertebrates, fishes, herpetofauna mammals using eleven modelling approaches.
Despite the ubiquity of pollutants in environment, their long-term ecological consequences are not always clear and still poorly studied. This is case concerning radioactive contamination environment following major nuclear accident at Chernobyl power plant. Notwithstanding implications evolutionary processes on population status, few studies concern evolution organisms chronically exposed to ionizing radiation exclusion zone. Here, we examined genetic markers for 19 populations Eastern tree frog (
There is general international acceptance of the need to demonstrate that environment protected from ionising radiation. In some countries requirements and guidelines for protection non-human biota are already in place. As a consequence number models approaches have been proposed estimation exposure The IAEA EMRAS programme's Biota Working Group has conducted most comprehensive intercomparison predictions these date. this paper, we present an overview activities concentrating on its...
Ecological Risk Assessment is used to evaluate the potential hazards environment that are attributable emissions of pollutants from industries. There guidance available regarding general ecological risk assessment process including problem formulation, exposure and effect analyses, characterization. In a first step, Screening-Level (SLERA) whether can put receptor ecosystems at or not. Concerning releases nuclear facilities under authorization, any SLERA challenging task because (1) large...
A number of models are being used to assess the potential environmental impact releases radioactivity. These often use a tiered assessment structure whose first tier is designed be highly conservative and simple use. An aim using this initial identify sites negligible concern remove them from further consideration with high degree confidence. In paper we compare screening outputs three freely available models. The these varied considerably in terms estimated risk quotient (RQ)...
