    Opis:
    The problem of environmental pollution with heavy metals present in Poland locally and relates primarily to industrial areas, but in some areas, in the vicinity of the former or current sources of emissions, water, soil and sometimes show a considerable degree of contamination. Heavy metals in soils may be a potential source of danger to plants and groundwater, and consequently - can be incorporated into the food chain [Karczewska et al. 2008 Kabata-Pendias 1993]. Downloading trace elements from contaminated soils by plants often exceeds their physiological needs, with the result that an excess of these elements in the soil can act phytotoxic.

    Opis:
    The problem of environmental pollution with heavy metals is still serious, despite numerous activities related to the reduction of anthropogenic emissions of these elements into the environment. There is a growing concentration of many toxic metals in soils and vegetation (remaining in close relation with the state of air quality), and especially in the environment of large urban agglomerations. The paper presents an assessment of the degree of contamination of soil and grass vegetation with heavy metals (Zn, Pb, Cu, Cd) in the vicinity of the communication over Warsaw. Research material obtained from the same locations (samples of soil and grass vegetation) was analyzed (AAS) in terms of the total concentration of metals in soils and its mobile form, while in plants is the total concentration of the corresponding trace the AAS atomic spectrometry. Based on the concentrations of metals in soil and vegetation samples were determined bioaccumulation factors. Methods mobile metals isolated by selective extraction of a 0.05 M EDTA solution. The results obtained were related to the results of similar research conducted two years earlier in 2005. Additionally the effect of leaching of soluble forms of metal particulate pollutants deposited on the surface of vegetation.

    Opis:
    Heavy metals can come from two types of sources: natural and anthropogenic. Natural origin of heavy metals associated with: volcanic eruptions, weathering of rocks, processes soil - creative, forest fires or evaporation of the oceans. Anthropogenic sources of pollution these elements is primarily the burning of fuels, both in power and heating plants and power plants as well as regional and local municipal boiler houses, as well as in the home. In addition to the natural environment gets heavy metals as a result of non-ferrous metals and iron, waste incineration and transport. The rapid development of technology and the changes that are occurring in the world today largely affect on the environment. One of the primary sources of pollution of the biosphere are industrial plants, which emit both gaseous substances (eg. Carbon monoxide, sulfur and nitrogen) and dust, containing all sorts of toxic substances. For the serious consequences of the development of civilization and industry should be spread include heavy metals [6]. Included in the atmosphere, dust and heavy metals fall to the ground parts of plants and enters the soil. Shall be collected by the roots of plants or animals grazing on the roads and thus incorporated into the food chain. These elements are not biodegradable.
