Ambient air. Measurement of bioaerosols - Planning and evaluation of plant-related plume measurements Ingestion-build-46800 5 UV absorption of extract1 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 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
