In contrast, in uncontaminated soils, total fractions showed lower δ ( 207 Pb/ 206 Pb) and δ ( 208 Pb/ 206 Pb) and higher δ ( 206 Pb/ 204 Pb) than EDTA-extractable fractions, which were consistently significant for δ ( 207 Pb/ 206 Pb) and δ ( 206 Pb/ 204 Pb) and partially significant for δ ( 208 Pb/ 206 Pb).
