The Indian Nitrogen Assessment: Sources of Reactive Nitrogen, Environmental and Climate Effects, and Management Options and Policies provides a reference for anyone interested in Reactive N, from researchers and students, to environmental managers. Although the main processes that affect the N cycle are well known, this book is focused on the causes and effects of disruption in the N cycle, specifically in India.

The book helps readers gain a precise understanding of the scale of nitrogen use, misuse, and release through various agricultural, industrial, vehicular, and other activities, also including discussions on its contribution to the pollution of water and air. Drawing upon the collective work of the Indian Nitrogen Group, this reference book helps solve the challenges associated with providing reliable estimates of nitrogen transfers within different ecosystems, also presenting the next steps that should be taken in the development of balanced, cost-effective, and feasible strategies to reduce the amount of reactive nitrogen.

This book focuses upon air pollution, types of air pollutants and their impact on plant physiological and biochemical systems. The book begins with a brief background on air pollution and continues with a discussion on different types, effects, and solutions to the pollution. The chapters that follow, explore the different effects of pollution on chloroplasts, respiration, biochemistry and physiology of plant cells. Moreover, it covers the basic concepts of atmospheric transport and transformations of pollutants, and issues of global change and the use of science in air pollution policy formulation. It also emphasises about the effects of air pollutants in altering plant response to common stresses, both abiotic and biotic - fields by giving the focus on the physiology of plant. This book act as a valuable tool for students in Environmental Science, Biological Science and Agriculture. It will be unique to environmental consultants, researchers and other professionals involved in airquality and plant related research.

During past few decades, air pollution and poor air quality have been the issues of common concerns. Degraded air has adverse effects on various system of plants by creating a stress which develops biochemical and physiological disorder in plants. Chronic diseases and/or lower yield have reported consequences of air pollution effect. A large number of biochemical and physiological parameters have been used to assess impact of air pollution on plant health. Photosynthetic machinery and respiratory system are the most affected domain of plants. However, the survival of plants depend on various internal and external factors such as plant community, types of air pollutants, geographical region, meteorological conditions and soil moisture etc. Plants respond to both biotic and abiotic stresses accordingly. Many tolerant plants survive easily even in higher air pollution region. Certain plant species absorbs selected gaseous air pollutants and henceplants are effective tool for air pollution remediation.
