- Intervention effect Regional sulfur dioxide levels caused no soybean injury or yield effect.
- Intervention effect At high concentrations, combined pollutants had less effect than the sum of their separate effects.
- Observation The dose response relationships were similar across two soil types.
- Intervention effect Neither pollutant changed the dose response relationship of the other except at high concentrations.
