Abstract

We investigated the lead isotopic ratio in organics and soil materials, along with leaded gasoline, one of the cause of increased lead pollution in the recent decades, using and inductively coupled plasma mass spectrometer, a relatively new method in the field of isotopic ratio measurements. Even if ICP-QMS technique is not as precise as the TIMS, it can provide short analysis time while having 0.1 - 1.5% relative standard deviation in measurement’s precision, which can be considered to be sufficient for most fields. Also, we provided data about lead isotopic ratio in lead, soil and vegetable sampled from western part of Romania.
