Agreed to take action to improve emission factor information on particulate matter(across all sectors), including chemical speciation, particle size and number;
The problem was that data on the chemical speciation and size distribution were not available and therefore the"unexplainable" part could not be comprehensively explained.
Further capacity-building might also be necessary in the area of surface andin situ observations, especially for chemical speciation measurements.
Chemical speciation including water content and size distribution(source identification) and 24h(or shorter) measurement frequency were necessary.
An expert from Switzerland gave a presentation about the potential interest of Aerosol Mass Spectrometer(AMS) and Aerosol Chemical Speciation Monitor(ACMS) measurements.
Tools are available for predicting chemical speciation in different types of environment and for assessing potential bioavailability and ecotoxic effects using different bioassays.
As a first priority, the particulate matter model used by EMEP should provide daily values of PM10 and PMx andbe able to characterize the chemical speciation of the aerosol.

The Task Force proposed to work with experts in the field of PM emissions to improve reporting andto meet the requirements of modellers with respect to size and chemical speciation of anthropogenic sources of PM.
Chemical speciation of particulate matter was important for source allocation and it was recommended that secondary inorganic particulate matter should be separated from the other components of particulate mass.
Level 2 sites provide additional parameters essential for understanding the process and for further chemical speciation of relevant components; they are an essential complement to the level 1 sites.
This includes dilution effects and/or reactions with other water sources, the potential for retention on natural andman-made absorbing surfaces, and the character of the metal's chemical speciation.
