||Mass spectrographic analyses were performed on various samples of street surface particulates. Using these results, the heavy metals which were determined to have the greatest water pollution potential (As, Cd, Cr, Cu, Fe, Pb, Mn, Hg, Ni, Sr, Ti, Zn, and Zr) were analyzed in each of about 75 samples collected nationwide in 10 cities. Other analyses conducted included: size affinities of the metals, solubilities and toxicities of the road surface runoff mixture, and certain organic analyses on selected samples. Additional sampling was conducted on rural road, highway and airport surfaces and particulates were analyzed for the following common water pollution parameters: BOD, COD and nutrients, plus selected heavy metals, for comparison with values representative of normal city streets.
