What is BS EN 17359 about?
BS EN 17359 discusses stationary source emissions on bioaerosols and biological agents. BS EN 17359 contains specifications for an active sampling of bioaerosols from exhaust air flowing through a defined cross-section of a stack. BS EN 17359 defines general principles that have to be considered during an isokinetic sampling campaign for bioaerosols by bubbling the exhaust air through a specific impinger designed for emission measurements. BS EN 17359 applies with culturable organisms that 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 the broad concentration ranges [1; 2; 3; 4].
Who is BS EN 17359 for?
BS EN 17359 on stationary source emissions on bioaerosols and biological agents is useful for:
- Food industry
- Waste recycling industry
- Testing laboratories
- Biological agents
- Human resources executives
- Occupational hygienists
- Other executives responsible for health and safety of employees
Why should you use BS EN 17359?
The method for measurement of bioaerosol emissions described in BS EN 17359 is based on EN 13284-1. The method describes the procedure of emission measurements under isokinetic conditions using an emission impinger in an out of stack configuration.
When performing bioaerosol emission measurements, exhaust air is passed through the entry nozzle and sampling probe before the particles suspended in the exhaust air are captured in the impinger sampling solution. It is known that particles can be deposited in bends and on the surface of the probe, therefore, rinsing of all of the parts of the sampling train upstream of the emission impinger is required after sampling.
BS EN 17359 discusses sampling and analysis, preparation of the sampling equipment, preparation of the emission impinger, preparation of the entry nozzle and the sampling probe, determination of appropriate sampling probe and sampling flow, performing bioaerosol sampling, leak test and sampling, recovery of deposits upstream of the emission impinger, determination of the mass of the sampling liquid, field blank value, analyticaBioaerosols and biological agents: Impingement method l blank value, and transport and storage.
