Designation:D486111Standard Practice forSampling and Selection of Analytical Techniques forPesticides and Polychlorinated Biphenyls in Air1This standard is issued under the fixed designation D4861;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the sampling of air for a variety ofcommon pesticides and polychlorinated biphenyls(PCBs)andprovides guidance on the selection of appropriate analyticalmeasurement methods.Other compounds such as polychlori-nated dibenzodioxins/furans,polybrominated biphenyls,poly-brominated diphenyl ethers,polycyclic aromatic hydrocarbons,and polychlorinated naphthalenes may be efficiently collectedfrom air by this practice,but guidance on their analyticaldetermination is not covered by this practice.1.2 A complete listing of pesticides and other semivolatileorganic chemicals for which this practice has been tested isshown in Table 1.1.3 This practice is based on the collection of chemicalsfrom air onto polyurethane foam(PUF)or a combination ofPUF and granular sorbent.1.4 Thispracticeisapplicabletomulticomponentatmospheres,0.001 to 50-g/m3concentrations,and 4 to 24-hsampling periods.The limit of detection will depend on thenature of the analyte and the length of the sampling period.1.5 The analytical method(s)recommended will depend onthe specific chemical(s)sought,the concentration level,and thedegree of specificity required.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specific hazardsstatements,see 10.24 and A1.1.2.Referenced Documents2.1 ASTM Standards:2D1193 Specification for Reagent WaterD1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3686 Practice for Sampling Atmospheres to Collect Or-ganic Compound Vapors(Activated Charcoal Tube Ad-sorption Method)D3687 Practice for Analysis of Organic Compound VaporsCollected by the Activated Charcoal Tube AdsorptionMethodD4185 Practice for Measurement of Metals in WorkplaceAtmospheres by Flame Atomic Absorption Spectropho-tometryE355 Practice for Gas Chromatography Terms and Relation-ships2.2 EPA Methods and Standards:EPA600/R-96/010b Compendium of Methods for the Deter-mination to Toxic Organic Compounds in Ambient Air3EPA 821/C-99-004 Methods and Guidance for Analysis ofWater,Versions 24EPA SW-846 Test Methods for Evaluating Solid WastePhysical Chemical Methods40 CFR 136 EPA Organic Chemical Analysis of Municipaland Industrial Wastewater52.3 NIOSH Methods:NIOSH Manual of Analytical Methods63.Terminology3.1 DefinitionsRefer to Terminology D1356 and PracticeE355 for definitions of terms used in this practice.3.2 Definitions of Terms Specific to This Standard:1This practice is under the jurisdiction ofASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved March 1,2011.Published March 2011.Originallyapproved in 1991.Last previous edition approved in 2005 as D4861 05.DOI:10.1520/D4861-11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Alsoavailableathttp:/www.epa.gov/ttnamti1/files/ambient/airtox/tocomp99.pdf4NTISPB99-500209(seehttp:/www.ntis.gov/products/epa-water-methods.aspx)5Also available at http:/ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&tpl=/ecfrbrowse/Title40/40cfr136_main_02.tpl6Also available at http:/www.cdc.gov/niosh/docs/2003-154/Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.1 dynamic retention effciencyability of the samplingmedium to retain the solution spike when air or nitrogen isdrawn through the sampling cartridge under normal operatingconditions and for the duration of the test period.The dynamicRE is normally equal to or less than the SE.3.2.2 relative retention time,(RRT)ratio of RTs for twochemicals for the same chromatographic column and carriergas flow rate,where the denominator represents a referencechemical.3.2.3 retention effciency,(RE)ability of the samplingmedium to retain a compound added(spiked)to it in liquidsolution.3.2.4 retention time,(RT)time to elute a specific chemicalfrom a chromatographic column,for a specific carrier gas flowrate,measured from the time the chemical is injected into thegas stream until it appears at the detector.3
