This study aims to estimate the accumulation of heavy metals (Cd, Pb, Zn and Cu) from soil in Dactylis glomerata L. plants from permanent meadows in the polluted area of Copșa Mică, Romania. The estimation of heavy metal accumulation in Dactylis glomerata L. plants was carried out based on a data set collected from permanent meadows used for grazing and hay production. The logarithmic power-type regression plots estimating the stochastic dependence between the total cadmium content in the aerial part of Dactylis glomerata L. plants and soil is statistically significant, and for Cu, Pb and Zn they are less significant. The variation of the total metal content (Cd, Cu, Pb and Zn) determined in the soil samples in the 0–20 cm layer according to the distance from the pollution source is statistically significant. The results of this study are important for the estimation of heavy metal (Cd, Cu, Pb and Zn) accumulation in Dactylis glomerata L. plants from permanent grasslands, which are consumed by animals.
