7 days left. Is your country endorsing the EN 16841?

16841 field inspection2   One week left for the EN 16841 to be implemented at national level by publication of an identical national standard or by endorsement. Just seven days to start working with this new European Standard that describes two methods for direct assessment of odours in ambient air: The grid method and the plume method.

    The dynamic olfactometry method described in EN 13725 is generally only suitable for measurement of odour emissions at the source, as the practical lower detection limit is typically ≥10 ouE/m3 (according to the Final draft of the EN 16841). Dynamic Olfactometry should not be applied directly to determine odour exposure in the field, although some authors claim that this is possible.

The Standard EN 16841:2016 on ambient odour measurement has been finally ratified

EN 16841 ratified norm on ambient odour measurement   The definitive text of the Standard EN 16841 is finally available in the official language versions (English, French and German) and it has been distributed to the CEN/CENELEC members. That means that although it might take a while for the EN standard to be available for purchase in any CEN member website, the process has already started. 

   This European Standard is based on field inspections and it describes two methods for direct assessment of odours in ambient air making direct use of the effect of odorants on the human sense of smell. This European Standard EN 16841 is divided in two parts, the EN 16841-1:2016 that describes a grid method which uses direct assessment of ambient air by panel members to characterize odour exposure in a defined assessment area and the EN 16841-2:2016 that describes a plume method for determining the extent of the downwind odour plume of a source.

Identification of Polluters with the Help of the Odourmap Webtool

sesion06 domingues07   In 2014 the residents of Kelsterbach suffered from an extreme annoyance due to odour impact in the residential areas. The nearby located WTP of the Stadtentwässerung Frankfurt was considered to be the source for the occurring odours.

    The operators have invested millions in the last years to optimize the plant concerning odour emissions. In this case, it was called into question if the water water treatment plant was the only source. The platform “Odourmap” was used for this study.
