Sample calculation for the amount of lead in the dose. DuPont HLR 581-94 Formula: Concentration of Lead (ppm) x Gavage Sample (g) x Dilution Factor = Lead in Sample (mg) Example: SoilPLW Mean lead analyzed = 244.5 ppm Gavage sample = 21.17 g soil + 30 g water = 51.17 g Dilution factor = 0.75 Concentration of lead derived from analysis during the study. Soil weight (21.17 g) was calculated in order to give each animal 17 mg oflead. This soil lead conentration is 803 ppm (information obtained from the study sponsor). The dose was prepared for 10 animals. 211.7 g soil was weighed and mixed with 300 mL Water; 30 mL of the mixture was given to each animal. In some cases, the soil did not mix well, so the amount of Water was increased to 400 or 500 mL. This additional water is the reason for the dilution factor used in the calculations. 244.5 ppm x 51.17 g x 0.75 = lead in sample (mg) 0.2445 mg/g x 51.17 g x 0,75 = lead in sample (mg) 9.383 mg = lead in sample -85* 2. Sample calculation for area under the curve (AUC). Formulas: Slope = -P / 2.303 Area oc = Value of Last Time Point /P Total AUC = Area + Area Example: Plasma Datafrom Animal #987, Group A (AEC 3-3) DuPont HLR 581-94 Area = 39.54825 B (slope + std.dev.) = -0.00264 0.00121 Concentration at Last Time Point = 0.058 p.g/mL Slope = -P / 2.303 -0.00264 = -p / 2.303 -0.00264 x 2.303 = -p 0.0060799 = p Area = 0.058 / p Area = 0.058 / 0.0060799 Area = = 9.5396306 Total AUC = Area + Area Total AUC = 39.54825 + 9.5396306 Total AUC = 49.087881 p.g(hr)/mL -86 DUP040004318 Blood Sample Label Animal Number Blood Sample Label Animal Number Blood Sample Label Blood Sample Label Animal Number Blood Sample Label Animal Number Blood Sample Label Animal Number APPENDIX G.
