[14C]-3,4-dichloroaniline (DCA) and its addition product to ortho-quinone (DCPC), which is regarded as a model for bound pesticide residues, were exposed in the surface layer of a cultivated Luvisol for 300 days at 28°C, and for 478 days at temperatures of 20, 25 or 28°C. The mineralization rate of DCA, assessed from the release of 14CO2, was highly temperature dependent, and was of the same order as that of the soil organic matter (SOM). The mineralization rate of DCPC was 10-20 times slower than that of DCA. About 84% of DCPC was incorporated quickly into humic fractions, mostly into humin. The incorporation of DCA was slower, but was markedly stimulated by increasing temperature. These results confirm that the disappearance of DCA in the soil is favoured by increasing temperature at least up to 28°C, which promoted both its mineralization and the formation of bound residues.
