### **Definition of Pollution** 

1. **General Definition**:

   - Pollution is the introduction of harmful substances or products into the environment, leading to adverse effects on ecosystems, human health, and the planet as a whole. It disrupts natural processes and can degrade air, water, and soil quality.

2. **Types of Pollution**:

   - **Air Pollution**: Contamination of the air with harmful substances such as particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and volatile organic compounds (VOCs). Common sources include vehicle emissions, industrial processes, and burning fossil fuels.

   - **Water Pollution**: Introduction of pollutants into water bodies like rivers, lakes, and oceans. This can include chemicals, heavy metals, pathogens, and nutrients that lead to issues such as eutrophication and harm to aquatic life. Sources include industrial discharges, agricultural runoff, and improper waste disposal.

   - **Soil Pollution**: Contamination of soil with chemicals such as pesticides, heavy metals, and hazardous waste. This can lead to reduced soil fertility, harmful effects on plant growth, and potential health risks for humans. Sources include improper waste disposal, use of chemical fertilizers and pesticides, and industrial activities.
