Introduction

Air pollution, a critical environmental challenge worldwide and in India, arises from both natural sources like volcanic eruptions and anthropogenic activities such as industrial emissions and vehicular exhaust. This unit delves into the sources and types of air pollutants, their adverse effects on health and the environment, and the mechanisms of pollutant transport and diffusion in the atmosphere.

Understanding these aspects is essential for addressing the severe air quality issues faced by major urban areas, developing effective air quality standards, and mitigating phenomena like acid rain that result from air pollution.
