Abstract:

The study carried out in order to estimate the distribution and accumulation of copper in soils and vegetation fromCop a Mic area used a radial network centered in the source of pollution – S.C. SOMETRA S.A. Cop a Mic . Soil andplant samples taken from the radial nodes of the network were analyzed to determine the content of copper. Values ofcopper content in plant ranged between 4.2 mg/kg and 97 mg/kg. Based on these results has been obtained a regressionequation that estimates the copper content in plants as function of the total copper content in soil. The spontaneousvegetation developed in the investigated area includes plants belonging to the following species: Amaranthusretroflexus, Artemisia vulgaris, Asclepias syriaca, Calamagrostis epigeios, Calamagrostis pseudophragmites, Cynodondactylon, Daucus carota, Equisetum arvense, Phragmites australis, Picris hieracioides, Setaria glauca, Sinapisarvensis, Verbascum phlomoides and Xanthium strumarium. The copper pollution doesn’t represent a major problem inCop a Mic area.
