Table 3: Average Pb isotopic signature of the anthropogenic inputs considering a binary mixing model for cores SS10T01 (N=10) and SSMPA (N=42 total core, and N=18, upper 17 cm) together with typical Pb isotopic signature of the anthropogenic sources to San Simón Bay (according to Álvarez Iglesias et al. [10]).
