Atmospheric pollutants can harm human health, damage ecosystems and reduce the sunlight reaching Earth's surface. The main pollutants considered here are carbon monoxide, sulfur dioxide, oxides of nitrogen and particulates.
Step-by-step lessons on AQA GCSE Chemistry 9.3.2 Properties and effects of atmospheric pollutants. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
