“…Petroleum contaminants may be strongly absorbed into organic matter, with a very low rate of desorption; this causes the formation of nonextractable bound residues (Kästner et al, 1995). The structure of this humic substance, which has the chemical structure of bound residues, is not completely clear; however, it generally reduces the bioavailability, mobility, and biocidal activity of petroleum in soil (Kloskowski and F ühr, 1987;Printz et al, 1995;Burauel and Führ, 2000). The formation of bound residues is promoted by adding the organic substrates that are produced by the growth and death of roots.…”

“…The total CO 2 fixed by the NaOH was evaluated by titrating an aliquot (8 ml) with N/5 HCl, in the presence of BaCl 2 20% and thymolphtalein, on days 4,6,8,12,16,20,30,43,50 and 60. On each sampling date, the replacement of the CO 2 -trapping solution by fresh solution allowed air renewal in the jars.…”

“…Secondly, we tried to observe the stabilisation process of sulcotrione in the soil, on the one hand through the examination of the evolution of sulcotrione availability at extraction [11,12], and on the other, with the evaluation of non-extractable sulcotrione residues [6,9,18]. 30 R.

-We investigated sulcotrione degradation in a sandy-silty brown soil. The agricultural field was divided into three small plots ten years ago, named plots R for reference, M for manure and CM for compost manure. The degradation experiment was conducted under controlled laboratory conditions using 14 C benzene uniformly ring-labelled sulcotrione. In the first month of the experiment, 80% of the residues was extractable with solvent, 55% of sulcotrione was degraded, including 45% into 2-chloro-4-methylsulfonylbenzoïc acid (CMBA), the most abundant metabolite of sulcotrione. 10% of the residues was mineralised. After two months, 40% of the residues was extractable, including 16% of sulcotrione, 25% was mineralised and 35% formed non-extractable residues. Soil amended with different organic matters favoured transformation of sulcotrione in soil. The fresh manure amendment activated mineralisation of 10%, and the compost manure amendment induced a lower ratio of extractable sulcotrione at a level of 5%.sulcotrione / degradation / persistence / soil / organic amendments / mineralisation Résumé -Dégradation de la sulcotrione dans un sol brun amendé avec différents apports organiques. La dégradation de la sulcotrione dans le sol a été évaluée en conditions de laboratoire à l'aide de la molécule uniformément marquée au 14 C sur le noyau benzénique. Le sol utilisé présente une texture limono-sableuse et est issu d'une parcelle divisée en trois sous parcelles recevant différents apports organiques depuis dix ans. Les terres issues de ces trois sous parcelles sont nommées respectivement terre R (référence), M (fumier) et CM (fumier composté). Lors du premier mois d'expérimentation 80 % des résidus restent extractibles, 55 % de la sulcotrione est dégradée dont 45 % en CMBA (2-chloro-4-methylsulfonylbenzoïc acide) son métabolite majeur. Seul 10 % des résidus sont minéralisés. Au bout de deux mois, 40 % des résidus sont extractibles au solvant dont 16 % de sulcotrione, 25 % sont minéralisés et 35 % forment des résidus non-extractibles. Lors d'amendements organiques, la transformation de la sulcotrione dans le sol est favorisée. L'apport de fumier active de 10 % la minéralisation des résidus et l'apport de fumier composté induit un ratio de sulcotrione extractible faible de l'ordre de 5 %.sulcotrione / dégradation / persistance / sol / amendement organique / minéralisation

“…Adicionalmente, Burauel & Führ (2000) observaram, também para condições da Alemanha, que cerca de 50 a 80 % do 14 C-carbono residual da aplicação de pesticidas, em condições de campo (lisímetros), permanece no solo como resíduo-ligado. Barriuso & Koskinen (1996) …”
