摘要：The concentrations of metallic pollution in soils and plants
along the ring road of Wrocław, Poland, have been determined.
Environmental samples were collected from the surface layer of the profile
within 2–3 m from the edge of the road. The analysis of metals (Pb, Cd,
Cr, Zn, Cu and Ni) has been carried out through FAAS and GFAAS
methods. The mineralizates of soils and plants were prepared in HNO3,
65% supra pure, using the Microwave Digestion System. The pH and
conductivity of the soil solutions were measured to evaluate their active
and exchangeable acidity and the salinity of the soils. The index of the
enrichment of soils in metals (Wn) and the bioaccumulation coefficient
(WB) have been determined. Also, histograms of the frequency of the
occurrence of metals in the environmental samples and the Pearson’s
correlation coefficients were presented. The results of metal concentrations
in soils were compared to the geochemical background in uncontaminated
soils of Poland. The assessment of the results in the soils was also made
relative to the standard, according to the Polish Ministry of Environment
Regulation from September 1st, 2016. During the assessment of the
bioaccumulation coefficients of metals in plants a reference was made to
the content of undesirable substances in feed in agreement with the Polish
Ministry of Agriculture and Rural Development Regulation from January
23rd, 2007.
