Airborne particles of biological origin are called bioaerosols. Natural and anthropogenic sources for bioaerosols spores are widely distributed in the environment. Anthropogenic sources can for example be agriculture and construction activities or waste treatment. 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 limit 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 plant 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. Plant-related measurements of bioaerosol concentrations in ambient air may be required in a number of regulatory situations. Examples of typical measurement 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 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 measurement method, the sampling strategy, the evaluation of the measured data, quality assurance and reporting.
