abstract = {An efficient extraction of sulfadiazine residues from soils
is difficult, as sulfadiazine is known to form quickly
sequestering residues. The objective of this study was to
optimize an exhaustive extraction for aged residues of
sulfadiazine and its two major metabolites,
N-acetylsulfadiazine and 4-hydroxysulfadiazine, from soil.
For this purpose two representative used agricultural soils
(Luvisol, Cambisol) were blended with manure derived from
[(14)C]sulfadiazine-treated pigs and incubated at 10 degrees
C in the laboratory. After different extraction tests with
various solvent mixtures (two- to four-component mixtures
with water, methanol, acetonitrile, acetone, and/or ethyl
acetate), different pH values (pH 4 and 9), and extraction
temperatures (up to 200 degrees C), soil extracts were
measured by liquid scintillation counting and liquid
chromatography coupled to tandem mass spectrometry. With
respect to sulfadiazine yields, stability of soil extracts,
and the amount of coextracted matrix, a microwave extraction
of soil (15 min, 150 degrees C) using acetonitrile/water 1:4
(v/v) is the method of choice for the exhaustive extraction
of aged sulfadiazine residues from soils.},
