Figure 8.
(A through F) Average ambient water-soluble and total metal (i.e., K, Mn, Fe, Cu, and Zn) and FPMOPDTT concentrations at the EPD and RFT sites. Blue boxes denote water-soluble (WS) concentrations; red boxes denote total concentrations (total Zn data for the RFT site are missing because of experimental issues). The data are also summarized in Appendix Table B.8. Concentration ratios of simultaneous 24-hour integrated filter measurements (N= 32) made at the EPD and RFT sites of (G) water-soluble metals and FPMOP and (H) total metals, OC, EC, and FPMOP (total Zn data for the RFT site are missing). The data are also summarized in Appendix Table B.9. (I) Ratios of water-soluble metals and FPMOP at the RFT and EPD sites. A ratio of one means that the water-soluble fraction was the same at both sites; a ratio larger than one means that the water-soluble fraction was larger farther away from the Connector. The data are also summarized in Appendix Table B.9. The horizontal lines represent medians, the empty dots represent means, the boxes enclose the 25th to 75th percentiles, and the whiskers enclose the 5th to 95th percentiles.
