Atmospheric Pollution
Primary and secondary pollutants, dispersion, deposition, air-quality effects and control.
How to study A-level Environmental Science
Move from process and system knowledge to quantitative evidence, field and laboratory method, uncertainty, environmental trade-offs and sustained conclusions.
Core concepts
Concept 1
Primary pollutants are emitted directly while secondary pollutants form through atmospheric reactions.
Exam cue: Identify the scope and evidence that control the atmospheric pollution decision before selecting a rule or method.
Concept 2
Weather, topography and stack conditions affect concentration and exposure.
Exam cue: Connect primary pollutants are emitted directly while secondary pollutants form through atmospheric reactions. with weather, topography and stack conditions affect concentration and exposure. and test the conclusion against control may target fuel, process, capture, transport behaviour or receptor exposure..
Concept 3
Control may target fuel, process, capture, transport behaviour or receptor exposure.
Risk pitfalls and guardrails
Applying a neighbouring topic or route rule without checking whether it belongs to Atmospheric Pollution.
Guardrail: Check the current official source, route and assessment boundary before relying on a memorised rule.
Memorising a label or number without being able to interpret evidence, explain the boundary or apply the method.
Guardrail: Check the current official source, route and assessment boundary before relying on a memorised rule.

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
