New Tolerances

1. PP 5F6904. (Docket ID number EPA-HQ-OPP-2005-0157). ABERCO, Inc., 9430 Lanham-Severn Road, Seabrook, MD 20706, proposes to establish a tolerance for residues of the fungicide propylene oxide in or on food commodities: Grape, raisin at 1.0 parts per million (ppm); fig at 3.0 ppm and plum, prune, dried at 2.0 ppm. ABERCO has submitted an enforcement method for determination of residues of propylene oxide, propylene chlorohydrin, and propylene bromohydrin in nutmeats, cocoa, and dried spices. Contact: Tony Kish, telephone number: (703) 308-9943; e-mail address: kish.tony@epa.gov.

2. PP 6E7144. (Docket ID number EPA-HQ-OPP-2007-0020). Tamico, Inc., 1950 Lake Park Dr., Smyrna, GA 30080, proposes to establish import tolerances for residues of the fungicide thiram in or on food commodities: Banana, whole at 0.5 ppm and banana, pulp at 0.3 ppm. Banana samples were analyzed according to analytical method meth-100, revision #4 , “Determination of Thiram in Raw Agricultural Commodities, Processed Commodities and Other Plant Material”. Detection and quantitation for thiram (as CS2) were conducted using gas chromatography (GC) employing sulfur-specific flame photometric detection (FPD). The limit of quantitation (LOQ) was 0.05 ppm. Contact: Bryant Crowe, telephone number: (703) 305-0025; e-mail address: crowe.bryant@epa.gov.

3. PP 6F7134. (Docket ID number EPA-HQ-OPP-2007-0178). Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Dr., Research Triangle Park, NC 27709, proposes to establish a tolerance for residues of the fungicide prothioconazole and its desthio metabolite in or on food commodities: Beet, sugar, roots at 0.25 ppm and beet, sugar, tops at 9.0 ppm. The analytical method for determining residues of concern in plant extract residues of prothioconazole and JAU6476-desthio and converts the prothioconazole to JAU6376-desthio and JAU6476-sulfonic acid. Following addition of internal standards the sample extracts are analyzed by liquid chromatography/tandem mass spectrometry (LC/MS/MS). Radiovalidation and independent laboratory validation have shown that the method adequately quantifies prothioconazole residues in treated commodities. The analytical method for analysis of large animal tissues includes extraction of the residues of concern, followed by addition of an internal standard to the extract. The extract is then hydrolyzed to release conjugates, partitioned and analyzed by LC/MS/MS as prothioconazole, JAU6476-desthio and JAU6476-4-hydroxy. The method for analysis of milk eliminated the initial extraction step in the tissue method. Contact: Bryant Crowe, telephone number: (703) 305-0025; e-mail address: crowe.bryant@epa.gov.

The LOQ allows monitoring of crops with chlorimuron-ethyl residues at or above the levels proposed in this tolerance. Contact: Sidney Jackson, telephone number: (703) 305-7610; e-mail address: jackson.sidney@epa.gov.

7. PP 6E7167. (Docket ID number EPA-HQ-OPP-2007-0302. Interregional Research Project Number 4 (IR-4), 500 College Road East, Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a tolerance for residues of the miticide bifenazate, (1-methylethyl 2-(4-methoxy[1,1'-biphenyl]-3-yl)hydrazinecarboxylate) and diazinecarboxylic acid, 2-(4-methoxy-[1,1'-biphenyl]-3-yl), 1-methylethyl ester (expressed as bifenazate) in or on food commodities: Papaya, star apple, black sapote, mango, sapodilla, canistel, and mamey sapote at 6.0 ppm; lychee, longan, Spanish lime, rambutan, and pulasan at 4.0 ppm; feijoa, guava, jaboticaba, wax jambu, starfruit, passionfruit, and acerola at 0.9 ppm; caneberry subgroup 13A at 6.0 ppm; wild raspberry at 6.0 ppm; edible podded legume vegetable, subgroup 6A at 4.0 ppm; succulent shelled pea and bean, subgroup 6B at 0.3 ppm; and succulent shelled soybean at 0.3 ppm. As D3598, a significant metabolite, was found to interconvert readily to/from bifenazate, the analytical method is designed to convert all residues of D3598 to the parent compound (bifenazate) for analysis. The method utilizes reversed phase high performance liquid chromatography (HPLC) to separate the bifenazate from matrix derived interferences, and oxidative coulometric electrochemical detection for the identification and quantification of this analyte. Using this method, the LOQ was 0.05 ppm. The LOD for this method, which varies with matrix, is 0.005 ppm. The analytical method for bifenazate and its major metabolite D3598 in animal samples used the same principles as the plant method with minor modifications. However, in animal samples, a separate aliquot of the extract was used to determine residues of A1530 and its sulfate (combined) in milk and meat samples (these metabolites appeared to be significant in goat metabolism studies). The extract was subjected to acid hydrolysis to convert the sulfate conjugate to A1530 before it was quantified by HPLC using fluorescence or oxidative coulometric electrochemical detectors (OCED).
