Pollutant - GCSE Chemistry Definition

A pollutant is any harmful substance released into the environment that can damage the air, water, or land. Pollutants can come from many sources, such as factories, vehicles, and household products. They can harm human health, damage ecosystems, and contribute to global problems like climate change and acid rain. In GCSE Chemistry, understanding pollutants is important for learning how to reduce their impact and protect the environment. Common examples of pollutants include carbon dioxide, sulphur dioxide, and plastic waste.
