The potential of elemental and isotopic analysis of tree bark for discriminating sources of airborne lead contamination in the UK.


Samples of tree bark, which accumulate airborne material, were collected from seven locations in the UK to provide an indication of the magnitude and source of lead pollution. Measurement of the Pb content and 206/207Pb stable isotope ratio by inductively coupled plasma mass spectrometry revealed significant differences between the sites. The concentration… (More)
