BS EN 15853:2010 pdf free.Ambient air quality—Stand ard method for the d etermination of mercury deposition.
BS EN 15853 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 requirements 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 with the requirements of Directive 2004/107/EC and to urban and industrial sites. The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Terms, definitions and abbreviations For the purposes of this document, the fllwing terms, definitions and abbreviations apply.
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 measurement model, covariances should also be taken into account when calculating the combined standard measurement uncertainty [ISO/IEC Guide 99 (VIM)].
coverage factor number larger than one by which a combined standard measurement uncertainty is multiplied to obtain an expanded measurement uncertainty.
Atmospheric deposition is defined as the sum of the depositions of sedimenting particles, non-sedimenting particles and gases. Total atmospheric deposition is the sum of dry deposition and wet deposition. Bulk deposition is the sedimenting part of the atmospheric deposition.
There is no method available to determine total atmospheric deposition in one measurement. The determination of the dry deposition requires micrometeorological measurements, taking into account the turbulent atmospheric transport processes. Wet deposition and bulk deposition, however, can be estimated using suitable collectors.BS EN 15853 pdf download.
