The first so-call “snuffle pole” has been put in place
in the Limburg city of Hasselt. The poles carry equipment to measure air quality.
In time around forty “snuffle poles” will be installed a locations across the
city. Hasselt is the first city with a snuffle post to measure amongst other
things levels of particulate matter and nitrogen dioxide. In time the scheme will
be rolled out across the region.
