HIGHLIGHTS

  • Atmospheric dry deposition fluxes in Taiwan.
  • The total deposition fluxes in Taiwan.
  • Contribution fractions of dry deposition fluxes contribute on total deposition fluxes.

ABSTRACT


Air pollution was getting worse and worse with the development of economic, and atmospheric deposition was an important mechanic for the removal of air pollutants. During 2017, the average dry deposition fluxes of total-PCDD/Fs-WHO2005-TEQ in various areas in Taiwan range between 57 (Lienchiang County in autumn) and 589 pg WHO2005-TEQ m–2 month–1 (Keelung City in winter), with an average of 221 pg WHO2005-TEQ m–2 month–1. The average total deposition fluxes of total-PCDD/Fs-WHO2005-TEQ in various areas in Taiwan range between 65 (Lienchiang County in autumn) and 681 pg WHO2005-TEQ m–2 month–1 (Keelung City in winter), with an average of 263 pg WHO2005-TEQ m–2 month–1. The fractions of dry deposition fluxes contribute to the total deposition fluxes range between 37.8% (Yilan County in winter) and 99.9% (Kaohsiung City in winter), with an average of 82.1%.
