文摘
- •
Isotopic discrimination can be an effective tool in identifying sources of Pb contamination
- •
Soils of former commercial orchards near Allentown, PA, USA contain anomalously high Pb and As
- •
Drinking water from wells sited within the orchards are known to contain anomalous concentrations of Pb
- •
Pb isotope data for well waters indicate anthropogenic, versus geogenic, Pb sources
- •
Pb isotope data for waters in house well systems reflect a legacy of industrial Pb present in the underlying aquifers
