Abstract [sv]

Resuspended road dust has, during the last years, proved to be a contributive

cause to high concentrations of inhalable particles (PM10) in ambient air.

The connection of PM10 to negative health effects has lead to an

environmental quality standard which will be in force from 1 st of January

2005. This calls for local and road authorities to investigate if the

standard is reached and if so, what measures have to be taken to reduce

concentrations. This study aims at investigating what methods and strategies

are in use in Swedish municipalities, their awareness concerning the dust

mitigating effectivity of measures taken and to investigate the knowledge on

road dust and sweeping in our neighbouring countries. The method was a

questionnaire to 103 municipalities and 7 regional road authorities as well

as literature and contacts with various road authorities in Norway, Denmark,

Finland and California. The results show that dusting from road are

considered a large problem among road authorities and that the problems are

worst during spring. The main cause to sweeping is comfort and sanitary

concerns followed by safety and health concerns. Wet sweeping is the most

common method and today no methods are in use especially intended for

reducing PM10 concentrations. Only 10 % of the respondents plan to improve

methods or strategies. In Helsinki the road dust problem is mainly blamed on

winter sanding and has been addressed since the late 80s. An ambitious

sweeping method consisting of four co-operating units is used. In Oslo, road

dust is blamed on studded tyres and the efforts have been focused on reducing

studded tyre frequency. Sweeping methods has been evaluated and the results

have been implemented in road and street sweeping. Neither in Helsinki nor in

Oslo have the sweeping methods and strategies yet proved to reduce PM10

concentrations. In California the "Rule 1186", demanding sweepers to be PM10

efficient, has resulted in some development, e.g. regenerative air sweepers

and vacuum assisted dry sweepers. All in all this report shows that the

knowledge about the contribution of road dust to PM,o and assumed

possibilities for more efficient sweeping to reach the environmental standard

is low among local and road authorities. In combination with the lack of PM10

data for Swedish municipalities and the near compliance with the

environmental quality standard, this is a potentially large problem.
