Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
The soil adsorption coefficient (Koc) value of C.I. FOOD BLACK 1 is estimated to be 41800000 L/kg, indicating that it is has a high sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Executive summary:

The soil adsorption coefficient (Koc) value of C.I. FOOD BLACK 1 is estimated to be 41800000 L/kg, indicating that it is has a high sorption to soil and sediment and therefore have negligible migration potential to groundwater.
