16、ernational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee ha

17、s been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical

18、standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodie

19、s for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

34、ll as the measurement procedures themselves (see Foreword). This part of ISO 16000 is applicable to the extraction, clean-up, and analysis from indoor air of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Sampling of PCBs, PCDDs

35、/PCDFs are described in ISO 16000-13. Both ISO 16000-13 and ISO 16000-14 are parts of the complete PCB/PCDD/PCDF measurement procedure. The sampling strategy to analyse PCBs, PCDDs/PCDFs and PAHs in indoor air is specified in ISO 16000-12. Several PCBs and PCDDs/PCDFs are considered to be potential

36、human carcinogens. There are 209 individual PCBs (congeners), 75 PCDDs and 135 PCDFs. The most toxic PCBs are those that are coplanar and structurally similar to PCDDs. The most toxic PCDD is 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). PCBs are emitted into indoor air primarily from concrete

37、 sealers, certain paints or electrical capacitors, all of which have been banned in recent years. The principal sources of PCDDs/PCDFs in indoor air are impurities in wood preservatives containing pentachlorophenol (PCP) and emissions from fires involving chlorinated products. Tracked-in soil and em

38、issions from nearby landfills and abandoned industrial sites may also contribute PCBs and PCDDs/PCDFs to the indoor environment. Total PCB concentrations in urban outdoor air typically range from 10 pg/m3to several hundred picograms per cubic metre. PCDDs/PCDFs are usually found in urban outdoor air

39、 at extremely low concentrations; e.g. femtograms per cubic metre. PCBs and PCDDs/PCDFs may be distributed between the gas and particle-associated phases in ambient or indoor air, depending on the temperature, humidity, degree of chlorination, their concentration, and their capacity to associate wit

40、h suspended particulate matter. These compounds, especially those of them having vapour pressures above 108kPa, will tend to vaporise from particle filters during sampling. Consequently, a back-up vapour trap is included for efficient sampling. Separate analyses of the filter and vapour trap will no

41、t reflect the original atmospheric phase distributions at normal ambient temperatures because of volatilisation of compounds from the filter and should not be attempted. This part of ISO 16000 is based on EN 1948-26, EN 1948-37, CEN/TS 1948-48, EPS l/RM/239, EPA SW 846 Method 8280B10, VDI 2464-211,

45、hlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) collected from indoor air on particle filters backed by polyurethane foam (PUF). The method incorporates specific analyses by high resolution gas chromatography combined with high resolut

46、ion mass spectrometry (HRGC/HRMS). The method provides accurate quantitative data for tetra- to decachlorobiphenyls and tetra- to octachloro-dibenzo-p-dioxins/dibenzofurans (total concentrations for each isomeric series). It is capable of detecting 0,2 pg/m3or lower concentrations of most PCBs and P

47、CDFs/PCDDs with air sampling volumes up to 360 m3or more in special cases. However, it may not be possible to detect all analytes at 0,2 pg/m3or lower, especially at lower sampling volumes. Precision under normal conditions can be expected to be 25 % or better and uncertainty 50 % or better. 2 Norma
