“…Formica was chosen because it provided a flat, hard surface. It would likely produce the maximum TEs that might be observed with similar household hard surfaces, as shown in earlier work (Rohrer et al, 2003;Bernard et al, 2008: Vonderheide et al, 2009a.…”

“…The experiments conducted in this study were a continuation of research that used similar sample preparation and analysis techniques that have been fully described earlier (Bernard et al, 2008;Vonderheide et al, 2009a, b). The focus of these experiments was the influence of contact of foods to a treated surface after various drying times and varying activity of frequency with and without recontamination of the surface between the contacts.…”

“…Foods were selected based on moisture and fat contents, which were representative of those used in earlier work (Vonderheide et al, 2009a). All were exposed to a 20 Â 20 or 400 cm 2 coupon of Formica laminate (purchased at a local hardware store) treated in a spray chamber with an aqueous emulsion containing five synthetic hydrophobic pyrethroids (bifenthrin, permethrin, cyfluthrin, cypermethrin, and deltamethrin) (Bernard et al, 2008). Formica was chosen because it provided a flat, hard surface.…”

“…The uniformity of the spraying was tested by placing multiple aluminum weigh boats within the chamber at various locations and statistically analyzed. The spray across the chamber in a singular event was shown to be consistent (Bernard et al, 2008). Sprayed surfaces were transferred to stainless steel desiccators The six coupons were randomly used during the experiments.…”

“…Sprayed surfaces were transferred to stainless steel desiccators The six coupons were randomly used during the experiments. One treated Formica surface was wiped with an isopropanol-moistened gauze pad (Bernard et al, 2008), one was covered with aluminum foil, and four were contacted with the food sample in the middle of the surface. Quality control samples to test the systems in obtaining data were performed to complete every exposure experiment.…”

Children's unstructured eating habits and activities may lead to excess dietary exposures not traditionally measured by the US Environmental Protection Agency. Influence of these activities on transfer of pesticides from treated Formica to foods was studied. The objective was to perform simulation experiments using four foods (bread, apple slices, bologna, and sugar cookies) exposed to treated Formica after varied time intervals between surface contamination and contact (1, 6, and 24 h) and frequency of contact with and without recontamination. Pesticides investigated included permethrin, bifenthrin, cyfluthrin, cypermethrin, and deltamethrin. Data will be used as input parameters for transfer efficiencies (TEs) within the Children's Dietary Intake Model (CDIM), which predicts total dietary exposure of a child. Pesticide transfer from surfaces to bologna and apples was more efficient than to bread and cookies. For the bread and cookies, all pyrethroids had a TE that ranged from below detectible levels to r4%. A combined average of 32-64% and 19-43% was transferred to bologna and apples, respectively, for the three contact times for all pyrethroids. The TEs of the varied time intervals indicated that increased time between contamination and contact showed little difference for bologna, bread, and cookies, but a significant difference for apples. As long as pesticide levels are measureable on surfaces in children's eating environment, it can be concluded that transfer of pesticides to foods will take place. Foods' characteristics had an important function in the transfer of pesticides when multiple contacts occurred. Regardless of recontamination, pesticides were efficiently transferred from the treated surface to bologna. The bologna did not reach a saturation point during the contacts. Pesticides were also efficiently transferred to apples, but reached a maximum TE during the second contact. The distribution of activity factors within CDIM needs to reflect the differences in the characteristics of the foods.

A surface sampling method for analysis of pesticide residues in pome fruit was studied by layer-by-layer scan from pericarp to kernel. Phoxim residues of apples, pears and papayas was determined by GC-MS, respectively, in core, different layers of pulp, peel ,as well as the whole fruit. Phoxim residue content was decreased when depth of the layer increased. It was inferred from experimental data the the appropriate depth of surface sampling is 2.5mm, 2mm and 3.5mm in apples, pears and papayas. Although the ratio of the pesticide in pericarp and the total (Cp/Ct) ranged from 6.241 to 9.262 in apple, 4.254 to 5.069 in pears, and 4.39 to 5.037 in papayas in different groups, the ratio of Cp/Ct and quality of specific group is essentially unchanged for a certain kind of fruit. According to the results, a conversion formula of the content of pesticide residues in whole fruit and pericarp was set, based on surface sampling method.
