This book aims to strengthen the knowledge base dealing with Air Pollution. The book consists of 21 chapters dealing with Air Pollution and its effects in the fields of Health, Environment, Economy and Agricultural Sources. It is divided into four sections. The first one deals with effect of air pollution on health and human body organs. The second section includes the Impact of air pollution on plants and agricultural sources and methods of resistance. The third section includes environmental changes, geographic and climatic conditions due to air pollution. The fourth section includes case studies concerning of the impact of air pollution in the economy and development goals, such as, indoor air pollution in México, indoor air pollution and millennium development goals in Bangladesh, epidemiologic and economic impact of natural gas on indoor air pollution in Colombia and economic growth and air pollution in Iran during development programs. In this book the authors explain the definition of air pollution, the most important pollutants and their different sources and effects on humans and various fields of life. The authors offer different solutions to the problems resulting from air pollution.
Air pollution is a problem affecting every part of our planet however, its global effects are poorly understood. This book provides the first truly global assessment of the scale of impacts of air pollution on crops and forests. The core of the book comprises assessments of the problem by experts from 12 different countries on every continent — describing the evidence of air pollution effects on crop yields and forest vitality with regard to environmental policies. These analyses are placed in the context of a global assessment of the scale of current and future air pollution levels, as well as in the socio-economic context of local production systems./a
Tropospheric ozone is a regionally distributed air pollutant that adversely affects both humans and vegetation. Surface-Level Ozone Exposures and Their Effects on Vegetation focuses on the formation, distribution, and transport of surface-level ozone; the characterization of its exposures; the mechanisms and processes involved in its deposition and uptake by plants; and its effects on the growth of crops and forest trees. State-of-the-art information is presented and the methodology for studying its effects on vegetation is critically reviewed. This background material leads to a discussion of the approaches for developing an air quality standard that will provide protection from the adverse effects of ozone, as well as suggestions for future research directions. Researchers and professionals in the utility industry, oil industry, and government environmental agencies; university instructors; and students will find that this book is filled with information that can be used on a daily basis in their work and studies.
Air pollution is ubiquitous in industrialized societies, causing a host of environmental problems. It is thus essential to monitor and reduce pollution levels. A number of plant species already are being exploited as detectors (for phytomonitoring) and as scavengers (for phytoremediation) of air pollutants. With advances in biotechnology, it is now feasible to modify plants for a wider range of phytomonitoring and phytoremediation applications. Air Pollution and Plant Biotechnology presents recent results in this field, including plant responses during phytomonitoring, pollution-resistant plant species, imaging diagnosis of plant responses, and the use of novel transgenic plants, along with reviews of basic plant physiology and biochemistry where appropriate. Researchers and students working in plant biotechnology and the environmental sciences or considering new areas of investigation will find this volume a valuable reference.

T. C. Hutchinson The NATO Advanced Research Workshop detailed in this volume was held in Toronto, Canada, in 1985. The purpose of the Workshop was to provide a "state of the art" report on our knowledge of the sensitivities and responses of forests, wetlands and crops to airborne pollutants. Approximately 40 scientific experts from nine countries participated. Most participants were actively involved in research concerning the effects of air pollutants on natural or agro-ecosystems. These pollutants included acidic deposition, heavy metal particulates, sulphur dioxide, ozone, nitrogen oxides, acid fogs and mixtures of these. Also invited were experts on various types of ecosystem stresses, physiologi cal mechanisms pertinent to acid deposition, and other areas that were felt by the director to be of direct relevance, including: effects of ethylene on vegetation, the physiology of drought in trees, the nature and role of plant cuticles as barriers to acid rain penetration, the use of dendrochronological techniques in reconstructing the time of onset and the subsequent progression of growth declines, the ability of soils to naturally generate acidity, the role of Sphagnum moss in natural peat land acidity, the use of lichens as indicators of changing air quality, and the magnitude of natural emissions of reduced sulphur gases from tropical rainforests and temperate deciduous forests. The Workshop included a series of invited presentations and subsequent group discussions. These presentations were designed to allow syntheses of our present knowledge as well as detailed questioning and discussion.
"The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.
Reviews literature concerning the effects of global climate change on forest plants and communities, and provides opinions on the potential impacts that climate change may have on Ontario forests. Sections of the review discuss the following: the climate of Ontario in the 21st century as predicted by climate models; forest hydrology in relation to climate change; insects and climate change; impacts on fungi in the forest ecosystem; impacts on forest fires and their management; plant physiological responses; genetic implications of climate change; forest vegetation dynamics; the use of models in global climate change studies; and forest management responses to climate change.
During late 1985, the Research Management Committee (RMC) of the National Crop Loss Assessment Network (NCLAN) decided the most ap propriate way to bring the NCLAN program to a successful conclusion was to hold an international conference. It was envisaged as an opportunity to present an overview of results from the NCLAN program and as a chance to view the results in the context of ongoing research by members of the international community. * Although we wanted the Conference to have an assessment orientation, it was also intended for the Conference to focus on current state-of-knowledge. The Conference was designed to overview the needs of crop loss assessment, current approaches to assessment, progress in the development of predictive models, the use of the information for economic predictions, and the application of the data in policy decisions. Every effort was made to assure a broad representation of ideas. The Conference program was developed to evaluate major issues that address regional/national assessments of impacts of atmospheric pollutants on agricultural production. Sessions were structured to address specific issues by invited speakers, and by contributed papers and posters. First, background needs for doing loss assessment research including specific approaches and a rather detailed review of the NCLAN program were addressed (Session I). Session II addressed the needs for defining the exposure environment (e. g. extrapolating to regional concentrations and exposure characterization). Field approaches for determining crop loss were reviewed in Session III.
