Multielement characterization of urban roadway dust

· Environ. Sci. Technol.; (United States)
A sample of urban roadway dust was physically fractionated into 30 subsamples, each having unique particle size, density, and ferromagnetic characteristics. Each subsample was analyzed for 35 elements. The resultant data were subjected to target transformation factor analysis to identify and quantify the sources that contribute to roadway dust. Results indicated that soil, cement, automobile exhaust emissions, rust, tire wear, and salt are the primary sources of particulate material. The analysis provided considerable insight into the physical and chemical characteristis of elements in urban dust. (2 diagrams, 35 references, 8 tables)
