    22、etermination of bioaerosols in ambient air: Part 1: Determination of moulds using filter sampling systems and culture-based analyses; Part 2: Planning and evaluation of plant-related plume measurements. The basic requirements of the determination of bioaerosols are first published as Technical Speci

    23、fications. The precision and the performance characteristics of bioaerosol measurements should be determined in comparison and validation trials in order to validate the method(s). Based on the validation results the Technical Specifications can be transferred to European Standards. For this purpose

    24、 it is intended to apply for mandated support by the European Commission and the European Free Trade Association using the Technical Specifications as a basis for validation measurements. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countri

PD CEN/TS 16115-2:2016CEN/TS 16115-2:2016 (E) 5 Introduction Airborne particles of biological origin are called bioaerosols. Natural and anthropogenic sources for bioaerosols are widely distribu

    27、ted in the environment. Anthropogenic sources can for example be agriculture or waste treatment activities. The purpose the measurement planning here described is to determine the mean plant- and/or source-related impact range of microbial air pollutants. As it has so far not been possible to set li

    28、mit values based on dose-response relationships, the mean impact range is to be used as a criterion for assessing the environmental impact of a plant. The scale of work for the plume measurements here described is necessary to obtain statistically representative data about the impact range of the pl

    29、ant and/or source, taking into account the great variety of influencing factors. Whilst a reduced measurement effort is possible in principle, this will lead to an increased measurement uncertainty. The objective of measurement planning is to analyse a given measurement problem and derive the associ

    30、ated requirements for organization, the measurement method, the sampling strategy, the evaluation of the measured data, quality assurance and reporting. The requirements set out in this technical specification are to ensure that plant-related ambient air measurements of microbial air pollution are p

    31、lanned in such a way as to enable a given task to be processed with sufficient accuracy and at justifiable cost. The aim is to ensure that the measured data obtained meet the applicable standards for representativeness and hence, enable maximum possible comparability. The procedure described in this

    32、 document is based on VDI 4251 Part 1 1. PD CEN/TS 16115-2:2016CEN/TS 16115-2:2016 (E) 6 1 Scope This document describes the general requirements to be taken into account in planning and implementing plant-related plume measurements of microbial air pollutants. A basic principle of this method is to

    33、 compare the concentrations in air unaffected by the activities of the plant (i.e. background air sampled upwind of the plant) with the concentration of bioaerosols in air downwind of the plant. It is this comparison that allows an assessment of the plant-related contribution and the mean spatial im

    34、pact range to be made. As it has so far not been possible to set limit values based on dose-response relationships, the mean impact range is to be used as a first criterion for assessing the environmental impact of a plant. The scale of work for the plume measurements described is necessary to obtai

    35、n statistically representative data about the impact range of the plant and/or source, taking into account the great variety of influencing factors. Plant-related measurements of bioaerosol concentrations in ambient air may be required in a number of regulatory situations. Examples of typical measur

    36、ement objectives and indicative application scenarios are presented in the document. This method specifies the simultaneous measurement of background and downwind air quality to reduce the risk of invalid comparisons resulting from changing background air concentrations. Another important principle

    37、of this method is the requirement for repeated measures to take into account day to day and seasonal variations in the processes governing bioaerosol emissions and dispersion. The objective is to analyse a given measurement problem and derive the associated requirements for organization, the measure

    38、ment method, the sampling strategy, the evaluation of the measured data, quality assurance and reporting. 2 Normative references The following referenced documents are indispensable for the application of this document.
