Dry deposition of metal elements on surrogate surfaces in the ambient air of central Taiwan

The atmospheric dry deposition flux of total-particle mass and metals was measured using different surrogate surfaces. Three different surrogate surfaces (overhead projection, T60A20 and Teflon) and two absorbent grease (Apenzion L grease and silicone grease) were considered. Dry deposition and particle concentration were samples simultaneously among three sampling sites (THU, JES and SES). Six individual metals including Ca, Fe, Zn, Pb, Cu and Cd were analyzed.
