Median particle size of SCPs generally decreases with distance (0 to ∼20km) downwind from the local coastal industrial area where SCP sources are distributed widely. This suggests that most SCPs found in the study area are derived from the industrial area. Samples with >40% of particles >20μm were predominantly collected within 2km of the industrial area, while samples with >40% of particles <10μm were mostly collected over 10km from the industrial area. Based on the results of our study and previous studies, we conclude that a higher proportion of particles of size >20μm indicates that the origin of SCPs is within a few kilometres upwind of the sample site, whereas the presence of higher proportion of particles <10μm indicates that their source is generally further than 10km upwind. However, other factors may affect the size distribution of SCPs at a given location (e.g. fuel type, quality of the particle precipitator and topography of the terrain). Pool deposits provide more suitable samples than lake sediments for investigating atmospheric precipitation.
