Ambient air. Sampling and analysis of airborne pollen grains and fungal spores for networks related to allergy. Volumetric Hirst methodWhat is BS EN 16868 Volumetric Hirst method about? BS EN 16868 discusses ambient air with a focus on airborne allergens such as pollen grains and fungal spores. BS EN 16868 specifies the procedures to sample continuously and to analyze the concentration of airborne pollen grains and fungal spores in ambient air using the volumetric Hirst type sampler or an even equivalent method assuring comparable data. BS EN 16868 describes both the sampling and the
