The fate of vegetal oil, ofeic acid methyl ester, in soif was investigated and compared ta that of a minerai oil. Experiments were bath carried out in laboratory conditions (soi/ columns or lysimeters) and in field conditions. A microbiology study was performed using the same soi/. Vegetal and minerai oils were applied an soi/ of lysimeter or field ot the phytosanitary application dose. Migration and primary degradation profiles of the oils and their metabolites were determined during a period of 120 days by gas chromatography analysis. Results showed a total degradation of the vegetal oil and its metabofites after 60 days whereas minerai oil required 90 days. A microbiology study was performed to identify some micro-organisms of the soi! and to evaluate ecotoxicity effects of the oils. Vegetal oil was revea/ed ta be Jess taxie thon minerai oil even at high concentration. The high biodegradability of the vegetal ester in soi/ was confirmed as we/1 os their environmental qua'Jities.
