Lead contamination in the roadside soils of slovenia

摘要

The level of lead contamination along the roadway Ljubljana to Zagreb was established in 184 soil samples. The samples were taken from two depths (0-5 cm and 15-20 cm) and at different distances from the roadway. The influence of terrain morphology, prevailing winds, geological parent material and type of vegetation was estimated. Heavy traffic si confirmed as main source of lead contamination (average enrichment factor 17) in soils.
