Book Synopsis Impact of Cesium on Plants and the Environment by : Dharmendra K. Gupta
Download or read book Impact of Cesium on Plants and the Environment written by Dharmendra K. Gupta and published by Springer. This book was released on 2016-10-14 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive and comprehensive knowledge to the researchers/academics who are working in the field of cesium contaminated sites, and the impact on plants. This book is also helpful for graduate and undergraduate students who are specializing in radioecology or safe disposal of radioactive waste, remediation of legacies and the impact on the environment. Radiocesium (137Cs and 134Cs) was released into the environment as a result of nuclear weapons testing in 1950s and 1960s (~1x1018 Bq), and later due to the Chernobyl accident in 1986 (8.5x1016 Bq) and Fukushima Daiichi Nuclear Power Plant in 2011 (~1x1017 Bq). 137Cs is still of relevance due to its half-life of 30 years. The study of radioisotope 137Cs is important, as production and emission rates are high compared to other radioisotopes, due to high fission yield and high volatility. This book contains original work and reviews on how cesium is released into the environment on translocation from soil to plants and further on to animals and into the human food chain. Separate chapters focus on the effective half-life of cesium in plants and on how different cultivars are responding in accumulation of cesium. Other key chapters focus on cesium impact on single cells to higher plants and also on remediation measures as well as on basic mechanism used for remedial options and analysis of transfer factors. The book rounds off by contributions on cesium uptake and translocation and its toxicity in plants after the Chernobyl and Fukushima accidents.
Book Synopsis Radionuclides in the Environment by : Clemens Walther
Download or read book Radionuclides in the Environment written by Clemens Walther and published by Springer. This book was released on 2015-10-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive and comprehensive information to researchers and academicians who are interested in radionuclide contamination, its sources and environmental impact. It is also useful for graduate and undergraduate students specializing in radioactive-waste disposal and its impact on natural as well as manmade environments. A number of sites are affected by large legacies of waste from the mining and processing of radioactive minerals. Over recent decades, several hundred radioactive isotopes (radioisotopes) of natural elements have been produced artificially, including 90Sr, 137Cs and 131I. Several other anthropogenic radioactive elements have also been produced in large quantities, for example technetium, neptunium, plutonium and americium, although plutonium does occur naturally in trace amounts in uranium ores. The deposition of radionuclides on vegetation and soil, as well as the uptake from polluted aquifers (root uptake or irrigation) are the initial point for their transfer into the terrestrial environment and into food chains. There are two principal deposition processes for the removal of pollutants from the atmosphere: dry deposition is the direct transfer through absorption of gases and particles by natural surfaces, such as vegetation, whereas showery or wet deposition is the transport of a substance from the atmosphere to the ground by snow, hail or rain. Once deposited on any vegetation, radionuclides are removed from plants by the airstre am and rain, either through percolation or by cuticular scratch. The increase in biomass during plant growth does not cause a loss of activity, but it does lead to a decrease in activity concentration due to effective dilution. There is also systemic transport (translocation) of radionuclides within the plant subsequent to foliar uptake, leading the transfer of chemical components to other parts of the plant that have not been contaminated directly.

Book Synopsis Nuclear and Radiological Emergencies in Animal Production Systems, Preparedness, Response and Recovery by : Ivancho Naletoski
Download or read book Nuclear and Radiological Emergencies in Animal Production Systems, Preparedness, Response and Recovery written by Ivancho Naletoski and published by Springer Nature. This book was released on 2021-05-31 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access volume explains how major nuclear and radiological emergencies (NREs) can have implications at local, national and international level. The response to NREs requires a competent decision-making structure, clear communication and effective information exchange. National veterinary services have the responsibility to plan, design and manage animal production system in their countries. These activities cover animal health, animal movement control, production control and improvement, and control of the products of animal origin before their placement on the market. Release of radionuclides after NREs can cause substantial contamination in the animal production systems. Critical responsibility of veterinary authorities is therefore to prevent such contamination, establish early response mechanisms to mitigate the consequences and prevent placement of contaminated products of animal origin on the market for human consumption. This work summarizes the critical technical points for effective management of NREs for national veterinary services.

This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
Book Synopsis Classification of Soil Systems on the Basis of Transfer Factors of Radionuclides from Soil to Reference Plants by : International Atomic Energy Agency
Download or read book Classification of Soil Systems on the Basis of Transfer Factors of Radionuclides from Soil to Reference Plants written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication sets out the results of a co-ordinated research project, jointly conducted by the IAEA, the FAO and the International Union of Radiologists, to assess the transfer of radionuclides from soils to plants and crops in temperate, tropical and sub-tropical ecosystems so as to identify systems in which transfer factors deviate substantially from average. The overall objectives of the project are to: improve radiological assessment models to facilitate better planning for emergency response and long-term agricultural countermeasures, particularly in developing countries, through the development of generic data and data relevant to local conditions; and to develop precise data on environmental parameters to be used when setting limits for authorised discharges from nuclear installations.
Book Synopsis Bioavailability of Contaminants in Soils and Sediments by : National Research Council
Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.
