Ambient air - Sampling and analysis of airborne pollen grains and fungal spores for allergy networks - Volumetric Hirst method; German version CEN/TS 16868:2015

Title (German)

Außenluft - Probenahme und Analyse luftgetragener Pollen und Pilzsporen für Allergienetzwerke - Volumetrische Hirst-Methode; Deutsche Fassung CEN/TS 16868:2015

Procedure

Overview

Airborne biological particles (pollen and fungal spores) occur and cause health effects of varying degrees. This standard specifies the procedure for continuous sampling and analysis of the concentration of airborne pollen grains and fungal spores in outdoor air using a volumetric collector based on the Hirst principle. The document describes both sampling and analytical procedures for use in allergy networks. Information is provided and specifications are given for handling the sampling system. The analysis is based on light microscopy for the identification and numerical detection of pollen and fungal spores.
