Analysis of soil-bound residues of 13C-labeled fungicide cyprodinil by NMR spectroscopy: Analysis of soil-bound residues of 13C-labeled fungicide cyprodinil by NMR spectroscopy. Dec, Jerzy; Haider, Konrad; Benesi, Alan; Rangaswamy, V.; Schaeffer, Andreas; Pluecken, Udo; Bollag, Jean-Marc (Laboratory of Soil Biochemistry Center for Bioremediation and Detoxification, The Pennsylvania State University, University Park, PA 16802, USA). Environmental Science and Technology, 31(4), 1128-1135 (English) 1997 American Chemical Society. CODEN: ESTHAG.Several substances are used for example 121552-61-2 which is its cas registry number. ISSN: 0013-936X. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Section cross-reference(s): 5 A mixt. of the 13C- and 14C-labeled fungicide was used to obtain structural information as well as information on the quant. distribution in the various fractions. Bound residues were accumulated by a 6-mo incubation of the labeled compd. with a clay loamy soil. Depending on the concn. of [13C]cyprodinil (500, 250, 80, and 3 mg/kg), binding ranged from 18% to 54% of the initial radioactivity. After methanol extn. of soil (10 g dry wt.) treated with 500 mg/kg (5.0 mg) of the fungicide, the amt. of unextd. bound material was equiv. to 0.9 mg of 13C-labeled cyprodinil. Upon fractionation, 0.21 mg of the bound fungicide was found in the dialyzed humic acid, 0.13 mg in fulvic acid (after extn. with CH2Cl2), and 0.24 mg in humin. The methylene chloride ext. from fulvic acid mainly contained unchanged cyprodinil (0.21 mg) that was apparently sequestered in soil by phys. forces. The humic acid fraction was dissolved in 1% NaOD and examd. by 13C-NMR. The NMR spectrum of the material from the control sample exhibited all the characteristic features of a typical humic acid. When the control humic acid was spiked with cyprodinil labeled uniformly with 13C at the Ph ring, four addnl. signals at 121.9, 124.4, 131.8, and 143.4 ppm could be distinguished in the NMR spectrum. However, when humic acid originated from the soil that was incubated with the phenyl-labeled fungicide, only two strong NMR signals, at 122.5 and 131.8 ppm, and two less significant signals around 142 and 162 ppm were obsd. The difference in the signal pattern indicated cleavage of the cyprodinil mol. between the arom. rings and independent binding of the Ph and pyrimidyl moieties to humic acid. .
