【 摘 要 】

he high density of traffic and intense industrial activity in urban areas generates significant impacts on public health. The aim of this paper is to study the heavy metals concentration associated with the atmospheric material (PM10 and PST) and the sediment accumulated on road sur- faces of Soacha (Colombia). It was determined the concentration (mg/ kg) of metals (Pb, Cd and Fe) by means of atomic absorption flame and inductively coupled plasma mass spectrometry. The results show a similar distribution of the metallic elements for the suspended and deposited par- ticles on road surfaces. The concentrations of Pb and Cd associated with PM10 are on average 17.6 and 4.7 times greater than those detected in the road sediment, respectively. The concentrations of Pb exceed the limits established by inhalation, ingestion and contact with the ground of the legislation used as reference.
