IB ESS 4.4.8 Eutrophication management levels
Practise selecting eutrophication controls at source, pathway and ecosystem level for nutrient pollution in aquatic systems.
How this is tested
- distinguish source reduction, pollutant-release control and ecosystem recovery strategies
- evaluate fertiliser or detergent alternatives for reducing nitrate and phosphate inputs
