International Code of Conduct on Pesticide Management


Book Description

The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Soil Pollution


Book Description

Soil pollution receives less attention when compared to air pollution and water pollution. However, soil pollution is grabbing more attention nowadays. Undoubtedly, soil is an indispensable environmental matrix for the growth of any terrestrial plants. Nevertheless, the rapid growth rate of population expansion and urbanization exceeds the sustainability and recovery capability of the ecosystem. This has virtually resulted in soil pollution. The sources of soil pollution can come from various point and non-point sources. Of the obvious and commonest ones are domestic wastes, untreated or insufficient treatment of industrial discharges, husbandry wastes and agricultural uses of fertilizers, pesticides and herbicides. The purpose of this book is to provide the latest, if not the complete, updated information regarding the soil pollution from three main perspectives, namely, sources, health effects and management strategies in the agricultural and urban areas. The intended readers of this book include academicians, policy-makers, university students, teachers and researchers. This book contains eleven chapters. All chapters in this book consist of sources of pollutants (heavy metal monitoring) (Chapters One, Three, Six, Seven, Eight, Ten and Eleven), the application of the monitoring data for the human health risk assessment (Chapters One, Four, Five and Nine), and lastly, management strategies for the polluted soils (Chapters Two, Ten and Eleven). This book presents a thorough compilation of existing information on soil heavy metal pollution in the form of critical review papers (Chapters One, Two, Ten and Eleven) as well as original research papers (Chapters Three, Four, Five, Six, Seven, Eight and Nine). The invitation of prominent scientists from Japan such as Prof. Hideo Okamura (Kobe University, Japan), Prof. Hiroya Harino (Kobe College, Japan), Dr. Ye Feng and Dr. Muzembo Basilua Andre (both from the National Institute of Environmental Sciences, Tsukuba, Japan), Prof. Alireza Riyahi Bakhtiari (Tarbiat Modares University, Iran), and Dr. Salman Abdo Al-Shami (University of Tabuk, Saudi Arabia), who co-authored some of the chapters have helped to improve the quality of the chapters in this book. Additionally, chapters from Prof. Chen-Feng You from the National Cheng Kung University (Taiwan), Prof. Monica Butnariu from Banats University of Agricultural Sciences and Veterinary Medicine (Romania) and Dr. Nadi Awad Al-Harbi from Tabuk University (Saudi Arabia) are also important elements in the construction of international readership for this book.




Plant Responses to Soil Pollution


Book Description

Soil is a vital support system for all life forms, and is directly or indirectly exposed to various pollutants and harmful chemicals. Any pollutant entering the soil system not only affects the quality of the soil, but also the plants and crops growing in it. Further, soil pollution has far-reaching impacts, since harmful chemicals can become biomagnified and enter the food chain, causing severe health concerns. Degraded soils can adversely affect various plant systems by creating biotic and abiotic stress, which increases the chances of biochemical and physiological disorders. Chronic diseases and lower yield have been reported as consequences of soil pollution. Drawing on decades of soil-related research, this book focuses on soil pollution, types of soil pollutants, and their impacts on plant physiological and biochemical systems, along with crop productivity. The book begins with a brief introduction to soil pollution and continues with a discussion of the different types and their effects, together with remediation methods. It highlights various sources of soil pollution such as herbicides, acidification, chemical fertilizers, sewage sludge, heavy metals, and radioactive pollutants. It also covers plant responses to combinations of pollutants, effects of pollutants on plant ultrastructure, interactions between pollutants and plant diseases, and interactions between pollutants and agricultural practices. In closing, it addresses the challenges involved in the restoration of degraded land, side effects of agricultural practices in the form of greenhouse gases, and strategies for mitigating these effects. Plant Responses to Soil Pollution offers an essential guide for students, environmental consultants, researchers and other professionals involved in soil and plant-related research.

Soil Pollution


Book Description

The soil is the medium through which pollutants originating from human activities, both in agriculture and industry, move from the land surfaces to groundwater. Polluting substances are subject to complex physical, chemical and biological transformations during their movement through the soil. Their displacement depends on the transport properties of the water-air-soil system and on the molecular properties of the pollutants. Prediction of soil pollution and restoration of polluted soils requires an under standing of the processes controlling the fate of pollutants in the soil medium and of the dynamics of the contaminants in the un saturated zone. Our book was conceived· as a basic overview of the processes governing the behavior of pollutants as affected by soil constituents and environmental factors. It was written for the use of specialists working on soil and unsaturated zone pollution and restoration, as well as for graduate students starting research in this field. Since many specialists working on soil restoration lack a back ground in soil science or a knowledge of the properties of soil pollutants, we have included this information which forms the first part of the book. In the second part, we discuss the partitioning of pollutants between the aqueous, solid and gaseous phase of the soil medium. The retention, transformation and transport of pollutants in the soils form the third section.




Soil Science: Agricultural and Environmental Prospectives


Book Description

Soil is the most important natural non-renewable resource developed over a longer period of time due to weathering of rocks and subsequently enrichment of organic matter. Soil provides habitat for numerous microorganisms and serves as a natural medium for plant growth, thereby providing the plants with anchorage, nutrients and water to sustain the growth. Soil also serves as a universal sink for all types of pollutants, purifies ground water and is a major reserve of carbon in the universe. The role of soils to provide ecosystem services, maintenance of environmental/human health and ensuring the food security makes it as the most important and basic natural resource. Soil Science helps us to elaborate and understand how the soils provide all these services. Soil Science also provides us the basic knowledge dealing with the origin of the soil parent material, weathering of parent material and the formation of soils, morphological, physico-chemical and biological features of soils, classification of soils and role of soils in the provision and maintenance of ecosystem services, food security and environmental quality. This book encompasses the various processes, functions and behaviour of soils very comprehensively to acquaint the students of soil, plant and environmental sciences about their role to perform different agricultural and environmental functions.
