Seasonal Variations In Airborne Dust Close To
Heavy Trafficated Roads In Trondheim, Norway
Author(s)
T. Hedalen
Abstract
In Norway estimates show that some 200,000 to 250,000 tons of particles, mostly asphalt, are
formed each year by wear of the top road pavements due to the extensive use of studded tyres
during the winterseason. During summer the dustfall ascribed the wear on road surfaces is 3 -
4 g/nf 30 days. There is an increase in dustfall during winterseason by a factor 2-4
depending on AADT. The increase in dustfall during winterseason is mainly due to an
increase in mineral content and mean particle size of the airborne dust. High concentrations
of PMio occure on days/periods with much dustfall.
