Book excerpt: Herbicides: Chemistry, Efficacy, Toxicology, and Environmental Impacts addresses contemporary debates on herbicide toxicology. The reader is offered a comprehensive overview of this complex topic, presented by internationally recognized experts. Information presented will inform discussions on the use of herbicides in modern agricultural and other systems, and their potential non-target effects on human populations and various ecosystems. The book covers these matters in concise language appropriate to engage both specialists in the research community and informed persons responsible for legislative, funding, and public health matters in the community at large. The use of herbicides is an essential pillar of modern agricultural production systems. Weeds, if uncontrolled, would reduce crop yield and result in massive economic damage. Recently, the heavy reliance on single herbicides has been linked to the development of weed resistance. To combat resistant weeds, farmers are advised to use a mix of several herbicides and to increase herbicide application rates. As a result, the toxicity of herbicides on human health and the environment has become a controversial topic. - Offers a comprehensive overview of herbicide science in modern agricultural systems - Addresses the complex problems that can arise from herbicide use and misuse, including weed resistance, pollution, and human health issues - Uses recent examples to demonstrate the topical nature of this issue

Download or read book Herbicide Residue Research in India written by Shobha Sondhia and published by Springer. This book was released on 2018-10-30 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.

Download or read book Herbicides written by Ruben Alvarez-Fernandez and published by BoD – Books on Demand. This book was released on 2012-01-20 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds severely affect crop quality and yield. Therefore, successful farming relies on their control by coordinated management approaches. Among these, chemical herbicides are of key importance. Their development and commercialization began in the 1940's and they allowed for a qualitative increase in crop yield and quality when it was most needed. This book blends review chapters with scientific studies, creating an overview of some the current trends in the field of herbicides. Included are environmental studies on their toxicity and impact on natural populations, methods to reduce herbicide inputs and therefore overall non-target toxicity, and the use of bioherbicides as natural alternatives.

Download or read book Transformation Products of Synthetic Chemicals in the Environment written by Alistair Boxall and published by Springer Science & Business Media. This book was released on 2009-09-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a synthetic chemical is released into the environment it may be degraded by abiotic and biotic processes. These degradation processes usually involve a cascade of reactions resulting in the formation of a number of transformation products. While we usually know a great deal about the environmental properties, fate and effects of parent synthetic chemicals, our understanding of the impacts of transformation products is much less developed. As such, this volume brings together chapters from leading researchers in the field of transformation products in the environment and describes how these products are formed, how they move through the environment, and their environmental effects. The book also presents modelling and analytical approaches for understanding the occurrence, fate and effects of transformation products in the environment. It is of interest to scientists in academia, the chemicals industry and regulators, as well as graduate students in Environmental Chemistry and Ecotoxicology.

Download or read book Chemistry and Ecotoxicology of Pollution written by Des W. Connell and published by John Wiley & Sons. This book was released on 1984-03-20 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution and its control are now one of the most serious problems in environmental management, affecting localized areas, regions, and, increasingly, the entire ecosphere. Chemistry and Ecotoxicology of Pollution provides a basic understanding of the chemical, toxicological, and ecological factors involved when major classes of pollutants act on natural systems. The nature and effects of these pollutants are examined from the primary level of their sources and chemical properties, through their interactions in the environment, to their ultimate ecological effects on organisms and ecosystems. Pollutants are divided into groups, with similar properties, and then the chemistry and ecotoxicology of each group is defined. More importantly, in collating and evaluating available information on pollution processes, the book develops unifying theories on the fundamental chemical and ecological nature of pollution processes. The book uses a conceptual framework to evaluate the impact of pollutants on the components and functions of natural ecosystems. It is based on the chemical and physical properties of a pollutant, its environmental behavior and fate, exposure to and toxic effects on organisms, their populations, communities, and responses of affected ecosystems. This sequence can be applied to known, potential, and emerging pollutants of concern. As government initiatives for the control of chemicals take greater effects, pollution research, particularly in ecotoxicology, will be further developed. Chemistry and Ecotoxicology of Pollution helps play an important role in determining the future direction of research activities in environmental management and pollution control on a worldwide scale. It is a basic resource for students (e.g. environmental chemistry, ecology, land and water management, environmental or public health, environmental engineering, and sustainability science), scientists, researchers, policy makers, and professionals in need of a clear understanding of the nature and effects of environmental pollution from an ecological perspective.
