19、E) 3 Foreword This document (EN 15853:2010) has been prepared by Technical Committee CEN/TC 264 “Air quality”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest
20、 by December 2010, and conflicting national standards shall be withdrawn at the latest by December 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all s
21、uch patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). There are currently only European Standard methods for the determination of the mercury concentr
22、ation in water samples (EN ISO 17852, Water quality Determination of mercury Method using atomic fluorescence spectrometry (ISO 17852:2006) and EN 1483, Water quality Determination of mercury Method using atomic absorption spectrometry) but no standard method exists for the determination of mercury
23、in precipitation, though OSPAR/EMEP reference methods are currently available for mercury in precipitation. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cr
24、oatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

25、853:2010 (E) 4 1 Scope This European Standard specifies a method for the determination of the total deposition of mercury. This standard can be used within the framework of the European Council Directive on Ambient Air Quality Assessment and Management and Directive 2004/107/EC. Performance requirem
26、ents with which the method should comply are specified in this European Standard. The performance characteristics of the method were determined in comparative field validation tests carried out at two European locations. This European Standard is applicable to background sites that are in accordance
27、 with the requirements of Directive 2004/107/EC and to urban and industrial sites. This standard allows the sampling of deposition using cylindrical deposition gauges, and analysis using Cold Vapour Atomic Absorption Spectrometry (CVAAS) or Cold Vapour Atomic Fluorescence Spectrometry (CVAFS) follow
28、ing existing harmonised and standardised procedures. The standard is applicable for the measurement of mercury in deposition between 1 ng/(m2d) and 100 ng/(m2d). The standard is validated for the deposition range listed in Table 1. Table 1 Working range of this standard method Working range ng/(m2.d
29、) Lower limit Upper limit 1 100 NOTE The range given is based upon the values measured in the field validation test. The upper and lower limits are the observed minimum and maximum values measured during the field validation tests. The actual lower limits of the working range depends on the variabil
30、ity of the laboratory blank, for bulk and wet-only collectors, and the precipitation. The method can be applied to higher and lower deposition rates provided that the collection characteristics are not compromised. 2 Normative references The following referenced documents are indispensable for the a

33、ions For the purposes of this document, the following terms, definitions and abbreviations apply. DIN EN 15853:2010-11 EN 15853:2010 (E) 5 3.1 Terms and definitions 3.1.1 ambient air outdoor air in the troposphere, excluding workplace air 3.1.2 atmospheric deposition mass flow rate (unit of mass per
34、 unit of area per unit of time) describing the process of the transfer of any species from the atmosphere to an environmental compartment, e.g. air to water, air to soil NOTE Atmospheric deposition is the sum of the depositions of sedimenting particles, non-sedimenting particles and gases. 3.1.3 bul
35、k collector equipment to collect bulk deposition NOTE Bulk collectors sample deposition at all times. A bulk sampler can consist of a funnel-bottle combination or a wide mouthed jar. 3.1.4 bulk deposition sum of the deposition of sedimenting wet and dry particles NOTE Bulk deposition is a part of th
36、e atmospheric deposition. 3.1.5 combined standard measurement uncertainty standard measurement uncertainty that is obtained using the individual standard measurement uncertainties associated with the input quantities in a measurement model NOTE In case of correlations of input quantities in a measur
37、ement model, covariances should also be taken into account when calculating the combined standard measurement uncertainty ISO/IEC Guide 99 (VIM). 3.1.6 coverage factor number larger than one by which a combined standard measurement uncertainty is multiplied to obtain an expanded measurement uncertai
38、nty NOTE A coverage factor is usually symbolized k ISO/IEC Guide 99 (VIM). 3.1.7 detection limit (DL), instrumental lowest amount of an analyte that is detectable using an instrument as determined by repeated measurements of a reagent blank 3.1.8 detection limit (DL), method lowest amount of an anal
39、yte detectable after the whole measurement process as determined by repeated measurements of different field blanks 3.1.9 dry deposition sum of the deposition of sedimenting dry particles, non sedimenting particles and gases NOTE Dry deposition includes the following processes: atmospheric turbulent
40、 diffusion, adsorption, absorption, impaction and gravitational settling. The dry deposition process is affected by the type of underlying surface and surface conditions. Dry deposition is a part of the atmospheric deposition. DIN EN 15853:2010-11 EN 15853:2010 (E) 6 3.1.10 expanded uncertainty prod
41、uct of a combined standard measurement uncertainty and a factor larger than the number one NOTE 1 The factor depends upon the type of probability distribution of the output quantity in a measurement model and on the selected coverage probability. NOTE 2 The term “factor“ in this definition refers to
42、 a coverage factor. NOTE 3 Expanded measurement uncertainty is termed “overall uncertainty“ in paragraph 5 of Recommendation INC-1 (1980) (see the GUM) and simply “uncertainty“ in IEC documents ISO/IEC Guide 99 (VIM). NOTE 4 For the purpose of this document the expanded uncertainty is the combined s
43、tandard uncertainty multiplied by a coverage factor k = 2 resulting in an interval with a level of confidence of 95 %. 3.1.11 field blank artificial sample (e.g. de-ionised water) taken through the same procedure as the precipitation sample, except that this has not been exposed to precipitation NOT
44、E It is transported to the sampling site, mounted in the sampling unit, returned to the laboratory and worked up in the same way as the deposition sample. 3.1.12 laboratory blank artificial sample (e.g. de-ionised water) taken through the same procedure in the laboratory as the precipitation sample,
45、 worked up in the same way as the deposition sample 3.1.13 measurement uncertainty non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information used NOTE 1 Measurement uncertainty includes components arising from systematic eff
46、ects, such as components associated with corrections and the assigned quantity values of measurement standards, as well as the definitional uncertainty. Sometimes estimated systematic effects are not corrected for but, instead, associated measurement uncertainty components are incorporated. NOTE 2 T
47、he parameter may be, for example, a standard deviation called standard measurement uncertainty (or a specified multiple of it), or the half-width of an interval, having a stated coverage probability.
