Recent reports indicate that atmospheric levels of reactive nitrogen species (RNS) are rising globally, primarily due to increased fossil fuel combustion for energy production and agricultural activities. Fossil fuel usage is altering air composition by adding compounds like NH₃ and NOₓ, along with related species such as HNO₃, HONO, NO₃, N₂O₅, NO₃⁻, peroxyacetyl nitrate (PAN), NH₄⁺, and others. These RNS are negatively impacting terrestrial and aquatic ecosystems, with several of them being major contributors to climate change. Elevated concentrations of RNS in air and water are also harmful to human health. Additionally, managing nitrogen waste poses a significant economic challenge, with its global impact estimated to range between US$340 billion and US$3.4 trillion annually when considering effects on human health and ecosystems. Food waste exacerbates these issues by disrupting the nitrogen cycle.

The book discusses the fundamental aspects of traditional air pollution topics as well as some more advanced topics (such as atmospheric brown cloud, trans-boundary movement of air pollutants, air transportation of radioactive material, biological air pollutants, etc.).

The Environmental and climatic issues varies from continent to continent and is unique to Asia. Understanding the issues does need lot of research and study material which students may not be able to gather due to shortage of time and resources. Hence an effort is made by authors gathering there experience and academic input from renowned universities of world. Climate change is real and coping with it is major concern in coming days. Most of the books written and sold in the past need updating and customizing. The general description of climate change and world will not help the professionals and students. It needs to seen area wise as a professional will work in specific geographic area. Hence an effort is made to collect data from Asia which host most populated countries along with ecological hot spots.
