The work of preparing International Standards is normally carried out through ISO techni
19、cal committees. Each member body interested in a subject for which a technical committee has 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 w
20、ith the International Electrotechnical Commission (IEC) on all matters of electrotechnical 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 Int
21、ernational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document m

34、 compounds by sorbent tube/thermal desorption/capillary gas chromatography Part 2: Diffusive sampling BS EN ISO 16000-12:2008vi Introduction ISO 16000 (all parts) specifies general requirements relating to the measurement of indoor air pollutants and the necessary conditions to be observed before or
35、 during the sampling of individual pollutants or groups of pollutants as well as the measurement procedures themselves (see Foreword). Sampling of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) also known as polychlorinated oxanthrenes, and polychlorinated dibenzofurans
36、(PCDFs) in indoor air is described in ISO 16000-13 whereas the corresponding extraction, clean-up and analysis by high-resolution gas chromatography/mass spectrometry is specified in ISO 16000-14. For sampling and analysis of PAHs, ISO 12884 may be employed. Several PCBs, PCDDs/PCDFs, and PAHs are c
37、onsidered to be potential 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). The toxicity of PCBs and PCDDs
38、/PCDFs are calculated according to an internationally accepted system (see Annex A and Reference 1). In 1997 (updated in 2005), a group of experts of the World Health Organization (WHO) fixed toxic equivalent factors (TEFs) for PCDDs/PCDFs and 12 PCBs, known as dioxin-like PCBs (Reference 1) (see An
39、nex A). These 12 dioxin-like PCBs consist of four non-ortho PCBs and eight mono-ortho PCBs (no or only one chlorine atom in 2-, 2-, 6- and 6-position), having a planar or mostly planar structure, see Table A.2. The principal sources of PCDDs/PCDFs in indoor air are impurities in wood preservatives c
40、ontaining pentachlorophenol (PCP) and emissions from fires involving chlorinated products. PCBs are emitted into the indoor air primarily from concrete sealers, certain paints, or electrical capacitors; their use for these applications has been banned in many countries in recent years. Emissions fro
41、m nearby landfills and abandoned industrial sites may also contribute PCBs and PCDDs/PCDFs to the indoor environment. The major origin of PAHs indoors is from combustion processes (mostly tobacco smoke and smoke from open fires). Except for the case where there are direct indoor sources, PCBs and PC
42、DDs/PCDFs enter indoor air from ambient air by ventilation. However, in ambient air these compounds are usually found at extremely low concentrations; e.g. several femtograms per cubic meter for PCDDs/PCDFs and about 10 pg/m3to several hundred picograms per cubic meter for total PCBs. The compounds
43、addressed in this part of ISO 16000 are usually distributed between the gas and particle phases in ambient or indoor air, depending on the temperature, humidity, degree of chlorination, their concentration and capacity to associate with suspended particulate matter. Separate analyses of the filter a
44、nd vapour trap will not reflect the original atmospheric phase distributions at normal ambient temperatures because of volatilization of compounds from the filter and should not be attempted. Shipping of PCDD/PCDF standard reference materials shall comply with national legal regulations. They shall
45、be transported in special containers that are commercially available. Handling should only be done by trained operators. The sampling strategy specified in this part of ISO 16000 presupposes familiarity with ISO 16000-1. This part of ISO 16000 uses the definition of indoor environments given by the
46、Expert Council on Environmental Matters (see ISO 16000-1 and Reference 2): dwellings having living rooms, bedrooms, DIY (do-it-yourself) rooms, sports rooms and cellars, kitchens and bathrooms; workrooms or work places in buildings that are not subject to health and safety inspections in regard to a
47、ir pollutants (e.g. offices, sales premises); public buildings e.g. hospitals, schools, kindergartens, sport halls, libraries, restaurants and bars, theaters, cinemas or other function rooms); and the interiors of private and public transport vehicles. This part of ISO 16000 is based on VDI 4300-23.

In the case of indoor air measurements, the careful planning of sampling and the entire measurement strategy are of particular significance since the result of the measurement may have far-reaching consequences, e.g. with respect to the need for remedial act
