The soils of the big cities, owing to the various anthropogenic activities, can be contaminated by
heavy metals. The surroundings of the roads with heavy traffic as significant metal emitter source can
be contaminated by heavy metals. The hobby gardens and the vegetable gardens directly along roads
can be potential risky for people since unknown amount of heavy metals can be accumulated into
organization of local residents due to consumption of vegetables and fruits grown in their own garden.
Most metals are well-known to have toxic characters but we have known little what extent these
metals exert influence on people living directly along road with busy traffic. During our research,
metal contamination has been investigated in the gardens near the roads with heavy traffic in Szeged
by measuring of metal contents in soil and plants samples. Enrichment factor has been calculated with
the help of control soil samples far from roads having heavily traffic. Besides determination of the
metal content of soil and plant samples, soil properties basically influencing on metal mobility has
been examined in order to characterize the buffering capacity of the studied soils. The health risk
quotients have also been determined to evaluate human health risk of the contaminated soils.
