The particulate matters in ambient air were sampled in Denizli, Turkey in winter and spring using Bergerhoff Method. The average dry deposition fluxes were calculated as 152.1 ± 30.7 mg m-2 day-1 and 333.9 ± 214.2 mg m-2 day-1 in spring and winter, respectively. The minimum dry deposition flux was observed as 115.4 mg m-2 day-1 on May 4-6, 2015 period, while the maximum flux was determined as 733.3 mg m-2 day-1 on November 7-9, 2016. No significant relation was observed between the dry deposition fluxes and the values of the temperature and the wind speed. It has been determined that the dry deposition fluxes in winter were approximately twice of the fluxes in spring. It can be said that the concentrations of particulate matters sourced from domestic heating in winter have higher concentrations than spring.
