Energy dispersive X-ray fluorescence analysis is applied to determine lead
pollution from various locations near the highway of Ankara - Istanbul. In
this proposed study, a complete optimization including sampling, homogeneit
y, particle size, critical thickness, measurement geometry for analysis of
soils and plants is carried out. It is observed the contribution of the mot
or transport, along the 25 km of highway, to the lead pollution is very con
siderable depending on heavy traffic.
