Abstract
In an earlier investigation, a major temporary effect on the lung function was determined, with a spirometer, in stevedoors on a ro-ro-ship exposed to diesel exhausts from trucks during a work shift. In the present study all the trucks used aboard were equipped with especially designed micro-filters mounted on the exhaust pipes. When the filter was in use, no significant effect on the lung function was measured. The removal of the particulate fraction of the exhausts by filtering modified, or possibly eliminated, the effect observed earlier. In designing an indicator of the biological effects of diesel exhausts the particle fraction should be taken into consideration.
