%X The re-suspended road dust samples from 53 sites that could cover basically the entire Beijing in summer,and aerosol samples from three representative sites in Beijing in four seasons were collected to study concentrations and spatial variations of elements and ions in re-suspended road dust and its contribution to the air-borne particulate pollution.Ca,S,Cu,Zn,Ni,Pb and Cd were main pollution elements,and Ca~(2+),SO~(2-)_4,Cl~-,K~+,Na~+and NO~-_3 were major ions in re-suspended road dust.Al,Ti,Sc,Co and Mg...
