Some broad assumptions were made and they are as follows: 100% uptake of the EC product (we know that wasn't likely to happen given the sprinkler situation, but this IS just an academic exercise), approximately 10 ml. of spray per tomato fruit (she did say she soaked them), a specific gravity of 1.0 for the chlorpyrifos solution (the label didn't list it), and an average helping size of one-100 gm. tomato. Using these assumptions and the application rates related by Harriet, theoretically she could have deposited as much as 349 ppm of chlorpyrifos on every 100 gram helping of tomato, squash, bell pepper, onion, etc. she harvested. That seems unreal, even if it is an academic exercise. What about using a more realistic estimate of 1 ml. of solution? The theoretical residue is then 3.49 ppm. Federal tolerances are listed in the sidebar. Squash, cantaloupe and herbs have no listed tolerances. +++++++++++++ (Web pop-up screen for calculations) Title: Theoretical Back-of-the-Envelope Calculations of Potential Maximum Residue To determine the chlorpyrifos concentration in the spray: 4 tsp/gal x 6.7 gm/100 ml x 4.93 ml/1 tsp x 1 gal/3785 ml = 0.000349 gm/ml To determine the weight of pesticide applied: 0.000349 gm/ml x 10 ml spray = 0.00349 gm To determine the weight of pesticide theoretically taken up by the tomato: 0.00349 gm pesticide per every 0.1kg tomato = 0.0349 gm/kg Which expressed in ppm equals 34.91 mg/kg or 3.49 ppm !"8Ѕтш5Ьюў— 1 3 4 ї№ш№ї№ш№ї№ї№ї№ *CJOJQJ CJOJQJ *CJOJQJ"9:;   =   Ъ Ы    F G q r s О П ћ ќ 2 3 4 §§§§§§§§§§§§§§§§§§§§§§§§§§§§"9:;   =   Ъ Ы    F G q r s О П ћ ќ 2 3 4 Аа/ Ар=!А"А# $ %А [$@ёџ$NormalmH <A@ђџЁ<Default Paragraph Font4 џџџџ4 4 4 ПХ—š Эаёє.16§ npЧЩ6џџwsutc2C:\WINDOWS\TEMP\AutoRecovery save of Document3.asdwsutc1\\FILE\CDANIELS\aen\2000\harriet calculations.docџ@€33)д334@GTimes New Roman5€Symbol3& ArialMCentury Schoolbook"qˆаh•ZI&мZI&C № $ЅРДД€20Jџџ!Pink is where I have changed textwsutcwsutcўџр…ŸђљOhЋ‘+'Гй0ˆ˜Фарьј  ( D P \hpx€ф"Pink is where I have changed textosinkwsutcs sutsut Normal.dotrwsutc.d1utMicrosoft Word 8.0e@R\ @fiЇР@И„Р №ўџеЭеœ.“—+,љЎDеЭеœ.“—+,љЎL hp|„Œ” œЄЌД М ъф i J1 "Pink is where I have changed text Title˜ 6> _PID_GUIDфAN{6616C9A5-87CA-11D4-9263-0000C09A6C7D} ўџџџ ўџџџўџџџ !"#ўџџџ§џџџ&ўџџџўџџџўџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџRoot Entryџџџџџџџџ РF^РрьІР(€1Tableџџџџџџџџџџџџ WordDocumentџџџџџџџџSummaryInformation(џџџџDocumentSummaryInformation8џџџџџџџџџџџџCompObjџџџџjObjectPoolџџџџџџџџџџџџрьІРрьІРџџџџџџџџџџџџўџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџўџ џџџџ РFMicrosoft Word Document MSWordDocWord.Document.8є9Вq
