Figure 1

Site location map for the La Oroya study area. The five study locations are shown as red circles, scaling the diameter to the median soil Pb concentration (186 ppm for Huayhuay to 3,177 ppm for La Oroya Antigua). Note the site distribution and the difference in soil Pb between the two distant sites Yauli and Huayhuay. The five Doe Run Peru air monitoring stations are shown as black squares, and the monitoring locations are adopted from Cederstav and Barandiarán [16].
