Conclusions:
The soil Adsorption Coefficient i.e Koc value of 2-benzylideneheptanal was estimated as 124900.0 L/kg (log Koc = 5.0967) by means of MCI method.The results indicate that the chemical 2-benzylideneheptanal is likely to to show very strong sorption to soil and sediment and show negligible migration to groundwater.
Executive summary:

The soil adsorption coefficient i.e Koc value of 2-benzylideneheptanal (CAS No. 6035 -94 -5) was estimated to be 124900.0 L/kg (log Koc= 5.0967) by means of MCI method (at 25 deg C). This Koc value indicates that the substance 2-benzylideneheptanal is likely to to show very strong sorption to soil and sediment and show negligible migration to groundwater.
