Download or read book Theories and Methods for Minimizing Cadmium Pollution in Crops written by Zhongyi Yang and published by Springer Nature. This book was released on 2022-04-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cadmium (Cd) contamination has raised increasingly global concern on food safety. The book was composed to bring comprehensive and valuable thoughts about the food safety management against heavy metal contamination. In this book, current status of cadmium contamination in agricultural soils and crops is systematically summarized. In order to reduce the risk of Cd pollution in crops, Cd pollution-safe cultivar (Cd-PSC) strategy, i.e. identifying, breeding and applying the cultivars with particularly low Cd accumulation capacity in edible parts even when grown in Cd contaminated soil, is proposed as a most effective, low-cost and environmental-friendly method for minimizing Cd pollution in crops. To describe the framework of the Cd-PSC strategy, a series research results on water spinach (Ipomoea aquatica Forsk) are summarized as a typical case. The latest findings about the Cd-PSCs of water spinach, including cultivar variation in shoot Cd accumulation, identification and verification of low- and high-Cd accumulating cultivars, stability of Cd accumulation capacity at the cultivar level, biochemical and molecular mechanisms of the cultivar-dependent Cd uptake, transfer and accumulation, breeding methods for improving Cd-PSCs, and so on, have been covered. This book will provide valuable theoretical and practical understandings for controlling Cd pollution in crops grown on agricultural soils with known or unknown risk of Cd contamination.
Download or read book Cadmium Toxicity Mitigation written by Amrit Kumar Jha and published by Springer Nature. This book was released on 2024-01-16 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers cadmium contamination of soil and plants, its sources, acute and long-term impacts on the environment and human health, and overall challenges posed by the global poisoning issue. Cadmium is among the elements that have been most broadly used by man over time, which has led to extensive pollution of surface soils, mainly associated with the mining and smelting of the metal and the addition of organic cadmium compounds to petrol. The release of cadmium into the atmosphere from various high-temperature processes has also led to surface contamination on a regional and even global scale. Cadmium is particularly firmly bound to humic matter in organic-rich soil and to iron oxides in mineral soil and is rather immobile in the soil unless present at very high concentrations. Plants grown on cadmium-rich soils incorporate cadmium, thus increasing the concentration of cadmium in crop plants. Cadmium thus enters the food chain through the consumption of plant material, which poses important health risks to humans and animals. In this book, readers will find out about the latest mitigation strategies, including a multi-disciplinary approach to address cadmium contamination. Recent methods in cadmium detoxification, speciation, and molecular mechanisms are included, and the book offers the knowledge required for efficient risk assessment, prevention, and countermeasure. Divided into 3 parts, this book brings together expert contributions on cadmium toxicity. In the first part, readers will find out about the different sources and distribution of cadmium in soil and plant ecosystems. The second part of the book outlines the health risks linked to cadmium toxicity, and in the final part, readers will discover sustainable cadmium toxicity mitigation strategies and potential applications of recent biological technology in providing solutions. This book is a valuable resource for students, academics, researchers, and environmental professionals doing fieldwork on cadmium contamination throughout the world.

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.
Download or read book Use of Humic Substances to Remediate Polluted Environments From Theory to Practice written by Irina V. Perminova and published by Springer Science & Business Media. This book was released on 2005-03-24 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).

Download or read book Reduction Cd in Soil rice by Si written by Vladimir V. Matichenkov and published by Nova Science Publishers. This book was released on 2019 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cd accumulation in rice grain is a world-wide problem because rice is the staple food of over half the world's population. Over the past few decades, many authors have reported that Si-rich substances can mitigate the negative influence of Cd on the growth of various plants, including rice. The main aim of this research was to summarize the data from literature and the investigation to understand the mechanisms of the Si effect on the migration and transportation of Cd in the paddy soil-rice system. This system was separated into two parts - the soil and the plant - and each part was studied separately. Si-rich soil amendments, Si fertilizers, and Si-based biostimulators were used in laboratory, greenhouse, and field tests. Several mechanisms of Si-Cd interactions in the soil-plant system (precipitation and sorption in soil, accumulation in roots and reduction Cd transport in apoplast and symplast of roots, stem and leaves), were investigated in detail and knowledge about these mechanisls were used for elaborating the practical recommendation. The field tests demonstrated that the use of Si-rich materials can reduce Cd in the rice grain by 50 to 90%, and other pollutants, including As, Cu, Hg, and Pb, by 40 to 95%. The combination of Ca- and Si-rich substances reinforced the reduction of Cd mobility and grain accumulation and is a prospective soil decontamination and food safety technology. The foliar application of Se can also provide an additional reduction of Cd accumulation in the rice grain. Our field tests showed that the application of Si-rich substances makes it possible to reduce traditional NPK fertilizer application rates by 20 to 30% without reducing the rice yield. This effect will also reduce the amount of Cd entering the cultivated soil. The data from the tests provides a reason to strongly recommend the use of Si-rich materials for the reduction of Cd accumulation in rice grain. Si-rich materials can also be used to reduce Cd accumulation in fruits of other cultivated plants.

Download or read book Cadmium in Soils and Plants written by M.J. McLaughlin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over forty years ago, concern was first focussed on cadmium contamination of soils, fertilisers and the food chain. Adverse effects on human health were first highlighted nearly 30 years ago in Japan with the outbreak of Itai-itai disease. Since then, substantial research data have accumulated for cadmium on chemistry in soils, additions to soils, uptake by plants, adverse effects on the soil biota and transfer through the food chain. However, this information has never been compiled into a single volume. This was the stimulus for the Kevin G. Tiller Memorial Symposium "Cadmium in Soils, Plants and the Food Chain", held at the University of California, Berkeley, in June 1997 as part of the Fourth International Conference on the Biogeochemistry of Trace Elements. This symposium brought together leading scientists in the field of cadmium behaviour in soils and plants, to review the scientific data in the literature and highlight gaps in our current knowledge of the subject. This series of review papers are presented here and deal with the chemistry of cadmium in soils, the potential for transfer through the food chain and management to minimise this problem. We hope this information provides a sound scientific basis to assist development of policies and regulations for controlling cadmium in the soil environment.
