Environmental Pollution is a critical area of study in Chemistry that delves into the various types of pollutants that contaminate the air, water, and soil, thereby posing serious threats to ecosystems and human health. This course material aims to equip students with a thorough understanding of the different types of pollution, their sources, classification, effects on the environment, and measures for effective control.

One of the primary objectives of this course is to help students identify the diverse forms of pollution and the specific pollutants associated with each type. Air pollution, for instance, involves pollutants such as hydrogen sulfide (H₂S), carbon monoxide (CO), sulfur dioxide (SO₂), oxides of nitrogen, chlorofluorocarbons (CFCs), and dust particles. Understanding the composition of these pollutants is essential for recognizing their environmental impacts.

Water pollution is another focus of this course, where students will explore sewage and oil pollution as prominent sources of contamination in water bodies. Additionally, the study of soil pollution will cover issues like oil spillage and the distinction between biodegradable and non-biodegradable pollutants that disrupt soil quality.

Moreover, this material will delve into the effects of environmental pollution on ecosystems and human health. By classifying pollutants as either biodegradable or non-biodegradable, students will grasp the lasting implications of pollution on biodiversity and the balance of nature. Furthermore, the course will highlight the urgent need for implementing effective measures to control pollution and mitigate its adverse effects.

Through this comprehensive course material, students will gain the knowledge and awareness required to become proactive stewards of the environment. By understanding the sources, effects, and control measures of environmental pollutants, individuals can contribute to sustainable practices and safeguard the planet for future generations.
