This edited book first gives an overview of issues in the studies of atmospheric sciences and then elaborates on extreme events in air pollution, their assessment, impacts, and mitigation strategies. It covers general overview of factors governing in atmosphere that lead to air pollution, description about recent and hazardous air pollution episodes, emergencies and extremes in atmospheric sciences, impact studies on living organisms and atmosphere related to emergencies and possible remedies/mitigation strategies which may also include green growth strategies for management. Increase in anthropogenic activities from different sources results in very high concentrations of air pollutants in the atmospheres and they lead to cause disturbance in seasonal cycles and atmospheric phenomena, ecological imbalance and change in the quality of air. These impacts are the major cause of short-term or long-term effects on living and non-living systems. In the recent years, several instances of extremes atmosphere and air pollution related emergencies causing accidental episodes, fog, smog, health related, heat and cold wave etc. are experienced. This book brings the attention on such issues in atmospheric sciences and discuss the disaster preparedness and management plus emergencies.  This book is valuable reading material for students in Environmental Science, Biological Science, Medical Science, Policy Planning, Disaster Management and Agriculture. It's useful for environmental consultants, researchers and other professionals involved in air quality, plant, humans and disasters related research.

Global climate change is one of the most serious threats to the environment of the earth and to the crop production. Crop's vulnerability to climate change stress caused by the greenhouse gases emission is a serious concern. This book describes various technologies and methods including the simulation of the future climate changes, studying the response of crop plants and characterizing their responses physiologically and biochemically. It includes the latest information of protocols and technologies for climate change research on agriculture. This book is of interest to teachers, researchers, climate change scientists, capacity builders and policymakers. Also the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, soil science, and environmental sciences. National and international agricultural scientists, policy makers will also find this to be a useful read.

The present book attempts to provide an insight about ¿Phyconanosynthesis¿. A new interdisciplinary technological approach emerged by the unification of two branches ¿Phycology¿ and ¿Nanotechnology¿. This book is an approach to reveal the potential aspect of algae to be used for the green development of nanotechnology. The advantages of using algal biological resources for the synthesis of various nanoparticles not only prohibit the future potential risks to the environment but also helps the nanotechnology with sustainability. The efficacy of nanoparticles synthesized by algae reported till now have been discussed. This is reader-friendly introduction of the emerging subject Phyconanosynthesis and therefore will be essential reading for post graduates and research scholars who are starting their dissertation in this line.

Under the Clean Air Act of 1971, a set of air pollutants are designated as criteria pollutants.
