Plants And Their Interaction To Environmental Pollution

Environmental pollution as a consequence of diverse human activities has become a global concern. Urbanization, mining, industrial revolution, burning of fossil fuels/firewood and poor agricultural practices, in addition to improper dumping of waste products, are largely responsible for the undesirable change in the environment composition. Environmental pollution is mainly classified as air pollution, water pollution, land pollution, noise pollution, thermal pollution, light pollution, and plastic pollution. Nowadays, it has been realized that with the increasing environmental pollution, impurities may accumulate in plants, which are required for basic human uses such as for food, clothing, medicine, and so on. Environmental pollution has tremendous impacts on phenological events, structural patterns, physiological phenomena, biochemical status, and the cellular and molecular features of plants. Exposure to environmental pollution induces acute or chronic injury depending on the pollutant concentration, exposure duration, season and plant species. Moreover, the global rise of greenhouse gases such as carbon monoxide, carbon dioxide, nitrous oxides, methane, chlorofluorocarbons and ozone in the atmosphere is among the major threats to the biodiversity. They have also shown visible impacts on life cycles and distribution of various plant species. Anthropogenic activities, including the fossil-fuel combustion in particular, are responsible for steady increases in the atmospheric greenhouse gases concentrations. This phenomenon accelerates the global heating. Studies have suggested that the changes in carbon dioxide concentrations, rainfall and temperature have greatly influenced the plant physiological and metabolic activities including the formation of biologically active ingredients. Taken together, plants interact with pollutants, and cause adverse ecological and economic outcomes. Therefore, plant response to pollutants requires more investigation in terms of damage detection, adaptation, tolerance, and the physiological and molecular responses. The complex interplay among other emerging pollutants, namely, radioisotopes, cell-phone radiation, nanoparticles, nanocomposites, heavy metals etc. and their impact on plant adaptation strategies, and possibility to recover, mitigation, phytoremediation, etc., also needs to be explored. Further, it is necessary to elucidate better the process of the pollutant’s uptake by plant and accumulation in the food chain, and the plant resistance capability against the various kinds of environmental pollutants. In this context, the identification of tolerance mechanisms in plants against pollutants can help in developing eco-friendly technologies, which requires molecular approaches to increase plant tolerance to pollutants, such as plant transformation and genetic modifications. Pollutant-induced overproduction of reactive oxygen species that cause DNA damage and apoptosis-related alterations, has also been examined. They also trigger changes at the levels of transcriptome, proteome, and metabolome, which has been discussed in this book.

Responses of Plants to Air Pollution examines the effects of air pollutants, individually and synergistically, on both higher and lower plants. The subject matter overlaps into a wide range of disciplines including agronomy, plant anatomy, biochemistry, cryptogamic botany, ecology, entomology, forestry, horticulture, landscape architecture, meteorology, microscopy, plant pathology, plant physiology, and soil science. The opening chapter presents an overview of sources of air pollution, costs of air pollution, and mechanisms of pollution injury to plants. Separate chapters on sulfur dioxide, ozone, fluorides, peroxyacyl nitrates, oxides of nitrogen, and particulates follow. Subsequent chapters are devoted to plant responses to combinations of pollutants; to effects of pollutants on plant ultrastructure, on forests, and on lichens and bryophytes; to interactions of pollutants with canopies of vegetation; to interactions of pollutants and plant diseases; and to interactions of pollutants with agricultural practices. This book will be useful to scientists in many disciplines as well as those who share the concern that clean air can no longer be expected to be the normal environment for plants or animals. The book will also be a valuable a reference work or text for upper level undergraduate students, graduate students, researchers, and growers of plants.

Examines all aspects of the interaction of plants with air pollutants. Synopsizes pollutant sources, their dispersion and transport, and their role in acid rain. Discusses methods to monitor and diagnose their effects. Examines how pollutants affect plants at the metabolic and cellular level, and how the organism and plant community responds. Includes discussion of the role of trace element toxicity, the uptake of pollutants, and the control of atmospheric pollution.

Environmental Pollution and Medicinal Plants presents information on the impact of environmental pollution on the performance of medicinal plants at various levels including damage detection, adaptation, tolerance, and physiological and molecular responses. This title draws attention not only to seeking new bioactive compounds for herbal drug preparation, but also on ensuring high standards of quality through evaluation of the chemical purity of medicinal plants growing under polluted conditions. It discusses the latest trends and responses of medicinal plants, indicating their tolerance and adaptation to environmental pollution. This book also focuses on secondary metabolites, phytochemicals, and bioactive compounds associated with medicinal plants growing in contaminated conditions. This book will be indispensable for students and professionals working in the field of environmental pollution, medicinal plants, and herbal medicine, as well as for plant biologists, economic botanists, molecular biologists, and biotechnologists. .

The study of air pollution effects on vegetation has made rapid progress in the last five years. Growing concerns about effects of future increases in temperature and carbon dioxide (C0 ) levels on plant life have altered 2 the perspective of plant biologists in the field of pollutant-plant inter actions. In many cases, it is anticipated that crops and trees will increasingly experience multiple stresses in an altered environment: an environment in which physiological processes will no longer be matched to climate. Because of this problem, a major part of the focus of the air pollution effects research has shifted since 1987. Moreover, recent advances in our understanding of plant metabolic and molecular responses to stress have made it clear that many abiotic stresses elicit similar fundamental mechanisms. Adaptation responses to drought, extremes of temperature, xenobiotics and air pollutants are now known to involve the response of both specific and common resistance mechanisms, which often include altered gene expression. The field of air pollution effects on vegetation has benefitted greatly from this unification since results obtained and advances made in allied fields are now directly relevant. The advent of molecular genetics has made possible the production of transgenic plants containing altered amounts of resistance gene products which enables the posing of experimental questions which could not be addressed only five years ago. Hypotheses concerning the relevance of specific metabolites and processes to known responses to air pollution stress can now be tested.
