Pollutant Properties, Pathways and Monitoring
Sources, pathways, transformations, sinks, persistence, bioaccumulation and monitoring design.
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
Environmental harm depends on dose, toxicity, persistence, mobility and receptor sensitivity.
Exam cue: Identify the scope and evidence that control the pollutant properties, pathways and monitoring decision before selecting a rule or method.
Concept 2
A source-pathway-receptor model helps identify effective control points.
Exam cue: Connect environmental harm depends on dose, toxicity, persistence, mobility and receptor sensitivity. with a source-pathway-receptor model helps identify effective control points. and test the conclusion against monitoring data require suitable location, timing, detection limits and baseline comparison..
Concept 3
Monitoring data require suitable location, timing, detection limits and baseline comparison.
Risk pitfalls and guardrails
Applying a neighbouring topic or route rule without checking whether it belongs to Pollutant Properties, Pathways and Monitoring.
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.
