  1. The intervals for collecting TSP were as follows: summer (Jun.–Aug. 2012, n = 12), autumn (Sep.–Nov. 2012, n = 12),winter (Dec. 2012–Feb. 2013, n = 42), and spring (Mar.–May 2013, n = 52)
  2. Numbers indicate the mean ± standard deviation
  3. Total PAHs means the sum of the concentrations of 10 PAHs (FR, PY, CHR, BaA, BaP, BbF, BkF, DahA, IcdP, and BghiP)
