Bioavailable Metals Analysis of Street Sediment

The concentration of Cd, Ni, Zn, and Pb in fine particulate street dirt was determined fro both a millipore water and a 0.5 M HCl extraction via ICPAES analysis. Samples were collected from two streets in Ashland, OR: Euclid Ave and chapman St. There was a statistical difference between metals contents sound at each site. HCl extraction pulled more metals from sediment than did water. Solid phase metals did not exceed EPA guidelines for Zn. Dissolved metals did not exceed environmental regulations. These results are preliminary and suggest more research be done on this sediment to determined whether a threat is posed to the receiving water body.
