How the change works
- 01 / Public decision
Industrial controls
- 02 / Physical change
Interrupted toxic releases
- 03 / Possible outcome
Reduced exposure
A pollutant can pass from water to organisms and diet. Preventing discharge is different from remedying after contamination.
Research and local documents ↓What the evidence tells us
The Japanese Ministry of the Environment reconstructs Minamata disease and the role of methylmercury in discharges and in the food chain.
Putting the choices into practice

The responseData and repair
The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
The remediation does not cancel the damage already suffered. Water, sediment, and organisms require separate measures.
Other possible benefits
Protecting health, fishing and trust in institutions.
