Applicant's summary and conclusion

Conclusions:
The soil adsorption coefficient i.e Koc value of sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate was estimated as 164.4 L/kg by means of MCI method
Executive summary:

The soil adsorption coefficient i.e Koc value of sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate was estimated as 164.4 L/kg (Log Koc: 2.216) by means of MCI method. The chemical is estimated to have low sorption to soil and sediment and moderate migration potential to groundwater.
