This report presents the database for the second phase of the ECE ICP material programme. Besides presenting the available data for the three exposure years 1995/96, 1996/97 and 1997/98, the report presents the spread in the yearly mean values for the exposure sites. To show the reductions in the air pollutions observed during the ruling time of the project, scatterplots for SO2, NO2 and O3 for the two years 1987/88 and 1997/98 are presented. They show that the reduction for SO2 at the sites during the ten years period has been 75% in average, NO2 the reduction has been 25% and for O3 no detectable change has been observed.

The main purpose of mission 16 was to introduce a new technique for analysis of volatile organic compounds (VOC) in air samples, and to do on the job training of the staff at Centre for Environmental Hazards Mitigation (CEHM) at the Cairo University, Giza. Due to major changes in staff at the laboratory during the visit, it was not possible to complete the training program according to the original plan. The equipment for sampling and analysis has been checqued and tested and further needs of equipment has been evaluated.

The POPCYCLING-Baltic model, typical multi-media mass balance model, divides the environment in 85 boxes or compartments, which are considered well-mixed and homogeneous, both with respect to the environmental characteristics and chemical contamination. These environmental phases are then linked by a variety of intercompartmental transfer processes.
