The content of trace elements in soils and plants near the highways of the Republic of Moldova

The results of determination of total and mobile forms of Mn, Cu, Zn, Pb in soils and plants near the traffic routes has been present. Research has highlighted the influence of emissions on the accumulation degree in the soils (0-10 cm) and plants of Mn, Cu, Zn, Pb in south direction in the interval of 5-15 m and 50-100 m distance from the road. Forest in the neighborhood serves as a barrier to accumulation of trace elements, depositing them in high concentrations in the litter. Accumulation of trace elements is more intense in vegetables cultivated near the highways; with high concentrations in leaves (cabbage, tomatoes).The cereals straw accumulate trace elements below the maximum allowed.
