The most common types of pollution include air, water, and noise pollution. Air pollution is caused by the release of harmful substances into the atmosphere, such as carbon dioxide, sulfur dioxide, and nitrogen oxides. Water pollution occurs when pollutants enter rivers, lakes, or oceans, causing changes in pH levels, oxygen content, and other chemical conditions. Noise pollution is the unwanted sound that can be heard from a variety of sources, including motor vehicles, industrial equipment, and loud music.
