Book Description
This book summarizes the new major research findings about formation mechanism and control strategies of haze in China, including basic theories, key technologies, equipment and platforms and the applications and implementations of control technologies, in implementing the Strategic Priority Research Program (Class B) of Chinese Academy of Sciences. Different types of air pollution processes experienced by the developed countries in different stages are out-breaking simultaneously in China in the recent years and resulting a new type of “haze chemistry smog” pollution, which is different from the “London smog” and the “Los Angeles photochemical smog”. This book provides a useful reference for related researchers, engineers and policy-makers engaged in atmospheric pollution research, prevention and control in China and other countries.

Book Description
To investigate the effects of HONO on smog pollution over the PRD-HK, comprehensive sources of HONO, including the heterogeneous formations on the ocean, urban, and vegetation surfaces, traffic emissions, new gaseous formation pathways, and recently proposed biological sources, were parameterized into WRF-Chem. The updated model was applied to study a severe multiple-day smog episode in August 2011 over PRD-HK. Our simulations suggested that the heterogeneous source of HONO from ground, ocean, and aerosol surfaces were the major contributor (~54%) to the observed HONO concentration in Hong Kong, followed by the biological source (~29%) and gaseous sources (~9%). The new HONO sources noticeably affect the regional oxidation capacity with an increase of 10-20% in OH radical and significantly enhanced the smog pollution with increases of 8-15%, 20-30%, and 10-15% in O3, nitrate, and total PM2.5, respectively, over the PRD-HK. The results clearly show that HONO plays an important role in photochemical smog pollution over the PRD-HK region and underscores the needs of implementations of comprehensive HONO formations into regional air quality models before utilizing them for refining ozone-control or PM2.5-control policies in the future.

Book Description
Frequent haze events have been happening in the North China Plain (NCP), and the severity of these events has attracted massive attention from both the public and the scientific community. Extremely high aerosol loadings in these haze events significantly influence visibility, human health and climate. Thus, improving understanding of haze pollution is of great importance. Furthermore, air quality modeling remains challenging. This thesis elucidated the roles of meteorology, secondary aerosol formation, regional transport, and aerosol feedbacks in winter haze formation, clarified the impacts of emission changes and meteorology changes on PM2.5 concentrations, directly emphasized the importance of implementing pollution control strategies using assessments of health and climate effects, and improved model performance in simulating sulfate and PM2.5 via incorporating heterogeneous sulfate formation and assimilating surface PM2.5 concentrations. This thesis also provided some implications for policy makers. Priorities should be given to control SO2, NH3, and OC emissions, which can be achieved by promoting the shift from coal/biofuel to cleaner energy, and by changing animal feeding and housing ways. In addition, more attention to greenhouse gases and absorbing aerosols is still necessary since absorbing aerosols play important roles in aerosol feedbacks, aerosol feedbacks can aggravate haze pollution, and increases in temperature may increase aerosol concentrations. To protect the public health, it is of great importance to predict air pollution episodes, release alerts of incoming severe haze episodes, and take emergency measures to reduce pollution levels.

Book Description
This book provides a dynamic simulation model based on input-output table. The model includes an objective function, i.e. maximizing economic and social development and three sub-models, including economic growth model, pollutant emission model and energy balance model. The data of 2012 is selected as the base period data. The haze control policy of Hebei Province is written into the model as an exogenous variable. Reducing the total PM2.5 emissions is an environmental constraint, which is used to eliminate the impact of natural factors on environmental quality. Lingo software is used to simulate this model. By comparing the socio-economic impacts in different scenarios, this book found the most effective policy combination of haze governance. Comprehensive haze governance policy recommendations provide experience for other regions of China and other developing countries. In this book, the dynamic simulation model of haze governance also provides a reference to other environmental policy simulations. This book is divided into five parts. The first part is an introduction. This paper mainly introduces the research background, research status at home and abroad, the purpose and significance of the study, the content and methods of the study, the key scientific problems to be solved and the expected results. In the second part, the current situation and existing problems of economic, social, energy and environment development in the study area are analyzed in detail. In the third part, a comprehensive evaluation model of dynamic optimization of haze control policy is constructed. The fourth part carries on the simulation experiment, and carries on the analysis to the experimental result. The fifth part puts forward the policy suggestions to realize the economic, social, energy and environmental development of Hebei Province. In this book, we have some understandings about haze governance. From the perspective of policy effect, the policy effects of subsidy for soil and water conservation, subsidy for development and utilization of clean energy, subsidy for new energy vehicles, motor vehicle restriction and subsidy for introduction of PM2.5 treatment technology are decreasing. Comprehensive policy can better achieve the goal of sustainable development of economy, energy and environment than single policy, and the effect of "source governance" policy is better than that of "end governance" policy.

Book Description
Applications of radioactive and stable isotopes have revolutionized our understanding of the Earth and near-earth surface processes. The utility of the isotopes are ever-increasing and our sole focus is to bring out the applications of these isotopes as tracers and chronometers to a wider audience so that they can be used as powerful tools to solve environmental problems. New developments in this field remain mostly in peer-reviewed journal articles and hence our goal is to synthesize these findings for easy reference for students, faculty, regulators in governmental and non-governmental agencies, and environmental companies. While this volume maintains its rigor in terms of its depth of knowledge and quantitative information, it contains the breadth needed for wide variety problems and applications in the environmental sciences. This volume presents all of the newer and older applications of isotopes pertaining to the environmental problems in one place that is readily accessible to readers. This book not only has the depth and rigor that is needed for academia, but it has the breadth and case studies to illustrate the utility of the isotopes in a wide variety of environments (atmosphere, oceans, lakes, rivers and streams, terrestrial environments, and sub-surface environments) and serves a large audience, from students and researchers, regulators in federal, state and local governments, and environmental companies.

Book Description
Atmospheric reactive nitrogen (N) emissions, as an important component of global N cycle, have been significantly altered by anthropogenic activities, and consequently have had a global impact on air pollution and ecosystem services. Due to rapid agricultural, industrial, and urban development, China has been experiencing an increase in reactive N emissions and deposition since the late 1970s. Based on a literature review, this book summarizes recent research on: 1) atmospheric reactive N in China from a global perspective (Chapter 1); 2) atmospheric reactive N emissions, deposition and budget in China (Chapters 2-5); 3) the contribution of atmospheric reactive N to air pollution (e.g., haze, surface O3, and acid deposition) (Chapters 6-8); 4) the impacts of N deposition on sensitive ecosystems (e.g., forests, grasslands, deserts and lakes) (Chapters 9-12); and 5) the regulatory strategies for mitigation of atmospheric reactive N pollution from agricultural and non-agricultural sectors in China (Chapters 13-14). As such it offers graduate students, researchers, educators in agricultural, ecological and environmental sciences, and policy makers a glimpse of the environmental issues related to reactive N in China .
