CAS RN:79-34-5

Soil Adsorption / Mobility

The Koc for 1,1,2,2-tetrachloroethane has been reported to be 79 using a silt loam soil(1). A log Koc of 1.92, corresponding to a Koc of 83(2) and a Koc of 118(3) in unspecified soils have also been reported. Adsorption Kd measurements in sandy, Pleistocene clay and silt clay soils(4) correspond to respective Koc values of 236, 216 and 173(SRC). According to a classification scheme(5), these Koc values suggest that 1,1,2,2-tetrachloroethane is expected to have high to moderate mobility in soil(SRC).
