Discuss how particulates from combustion can affect both human health and the environment.

Particulates can cause respiratory problems in humans, leading to conditions such as asthma and bronchitis. Environmentally, they can contribute to global dimming by reflecting sunlight, which can disrupt local climates and affect plant growth.

A strong answer should directly address the approved learning objective to evaluate data or statements about atmospheric pollution and its effects. This question belongs to Properties and effects of atmospheric pollutants within Common atmospheric pollutants and their sources, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to evaluate, and keeps the wording specific to AQA GCSE revision.
