BS PD CEN/TS 16115-2:2016 describes the general requirements to be taken into account in planning andimplementing plant-related plume measurements of microbial air pollutants. A basic principle of thismethod is to compare the concentrations in air unaffected by the activities of the plant (i.e. backgroundair sampled upwind of the plant) with the concentration of bioaerosols in air downwind of the plant. Itis this comparison that allows an assessment of the plant-related contribution and the mean spatialimpact range to be made. As it has so far not been possible to set limit values based on dose-responserelationships, the mean impact range is to be used as a first criterion for assessing the environmentalimpact of a plant.The scale of work for the plume measurements described is necessary to obtain statisticallyrepresentative data about the impact range of the plant and/or source, taking into account the greatvariety of influencing factors.Plant-related measurements of bioaerosol concentrations in ambient air may be required in a numberof regulatory situations. Examples of typical measurement objectives and indicative applicationscenarios are presented in the document. This method specifies the simultaneous measurement ofbackground and downwind air quality to reduce the risk of invalid comparisons resulting fromchanging background air concentrations. Another important principle of this method is the requirementfor repeated measures to take into account day to day and seasonal variations in the processesgoverning bioaerosol emissions and dispersion.The objective is to analyse a given measurement problem and derive the associated requirements fororganization, the measurement method, the sampling strategy, the evaluation of the measured data,quality assurance and reporting.Cross References:CEN/TS 16115-1EN ISO/IEC 17025ISO/IEC 17025EN 13098:2000 VDI 4251-1:2007VDI 4252-2VDI 4253-2VDI 3786-1VDI 3786-2
