Pollution - GCSE Chemistry Definition

Pollution is the release of harmful substances, called pollutants, into the environment. It can damage the air, water, or land. In chemistry, pollution often comes from burning fossil fuels like coal and oil, which releases gases such as carbon dioxide and sulphur dioxide. These gases can cause problems like global warming and acid rain. Pollution can also occur when waste products from factories or homes enter rivers and oceans, harming water quality and aquatic life. Understanding pollution helps us develop ways to reduce its impact and protect the environment.
