  2. 29h TaskForce Meeting, 29thFebruary – 4thMarch 2016, Dubna, RussianFederation The term heavy metal Metallic chemical element that has a relatively high density and is toxic or poisonous even at low concentrations. The most significant environmental pollutant heavy metals are: cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn), in large amount the iron (Fe) and manganese (Mn) are pollutants, too. These heavy metals are presentin the environment due to weathering of soil-forming rocks and minerals, and by the emission of chemical fertilizers, soil improving materials, pesticides, organic fertilizers, waste water, waste water slobs, due to industrial and mining activity and due to traffic (Hegedűs, 2002).

  6. 29h TaskForce Meeting, 29thFebruary – 4thMarch 2016, Dubna, RussianFederation The aim of investigation Because of the environmental pollution there is an increased attention on the potentially toxic elements and on the dangers related to heavy metals. Detailed and intensive examinations are necessary in order to avoid extensive contaminations. A lot of information is needed about different environmental elements to understand the fast changes in environment and to control the environmental laws. Therefore, it is important to evaluate different studies in the environment the deposition of heavy metals. Some plants, can be very useful as bioindicators in order to obtain information about heavy metal concentration data derived from the air pollution monitoring.
