Concentrations of TSP and chemical constituents in TSP collected at Yurihma. Atmospheric concentrations of a TSP, b Fe, c Pb, d SO4 2−, e NO3 −, and f total PAHs were analyzed. The intervals for collecting TSP were as follows: summer (June–August), autumn (September–November), winter (December–February), and spring (March–May). Arrows show dates of Asian dust events registered by the JMA (March 8, 9, 19, and 20) or indicated by LIDAR (March 7, 8, 9, and 19, April 30, and May 30). Horizontal lines show the 90th percentile of TSP (61.0 μg/m3), Fe (1061 ng/m3), Pb (32.4 ng/m3), SO4 2− (11.8 μg/m3), NO3 − (3.10 μg/m3), and total PAHs (1.81 ng/m3). Total PAHs means the sum of the concentrations of 10 PAHs (FR, PY, CHR, BaA, BaP, BbF, BkF, DahA, IcdP, and BghiP)
