Pollutants and their effects
Pollutants and their effects
Atmospheric pollutants can harm human health, damage ecosystems and alter how much sunlight reaches Earth's surface. Sulfur dioxide and oxides of nitrogen each have two separate effects: they can irritate the airways, and they can contribute to acid rain. Acid rain can then damage ecosystems, plants, aquatic life and buildings.
Step-by-step lessons covering AQA GCSE Chemistry 9.3.2 Properties and effects of atmospheric pollutants for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
