Abstract
Fate of linear alkylbenzene [14C] sulfonates (LAS-Ca, LAS-Na) were investigated in two kinds of soil under upland condition in a biometric flask and 14C-LAS-Ca showed as same fate as 14C-LAS-Na. Although there was a remarkable difference in the amount of unextractable residue between tested soils, the patterns of 14CO2 evolution were similar, reaching 3045% of the applied 14C at 60d after treatment. It was cleared that the benzene ring of LAS was inorganized in unsatured soils.
Nomovements of 14C-LAS-Ca and 14C-LAS-Na in peanuts were recognized even at 30d after foliar application.
