This document contains specifications for active sampling of bioaerosols from exhaust air flowing through a defined cross-section of a stack. It defines general principles that have to be taken into account during an isokinetic sampling campaign for bioaerosols by bubbling the exhaust air through a specific impinge designed for emission measurements. In this document the application with culturable organisms is specified but the same principle might be applicable for non-cultural based methods (e.g. molecular and/or enzyme-based methods). The impinger is designed to allow a sample volume flow of 1 m3/h to 1@8 m3/h@ or 16 l/min to 30 l/min@ respectively@ and has been tested with regard to various microorganisms within broad concentration ranges [1; 2; 3; 4]. 1)
