Particulates - GCSE Chemistry Definition

Particulates are tiny solid or liquid particles found in the air. They can come from natural sources like volcanoes, dust storms, and sea spray, or from human activities such as burning fossil fuels in cars and factories. Particulates are often so small that they can only be seen under a microscope. The smallest particulates can be harmful to human health because they can enter the lungs and even the bloodstream. In GCSE Chemistry, particulates are studied as a type of air pollution, helping us understand how human activity affects air quality and the environment.
