Particles with diameter between about to contained in the so-called accumulation mode, are mainly formed by coagulation and generated from condensation processes. Particles in this size range can also be produced from secondary formation and natural sources such as sea spray or the resuspension of fine soil or dust, although less than 10% of mass concentration of the fine fraction ( | DRAFT VERSION AMBIENT AIR POLLUTION CARBON MONOXIDE POSITION PAPER 17 March 1999 European Commission Directorate-General XI This document has been prepared by the Commission s consultant Dr. . van den Hout TNO Institute of Environmental Sciences Energy Research and Process Innovation Apeldoorn The Netherlands with the assistance of the following experts A.
