| Tartalmi kivonat: | This paper is a study on identifying the amount of heavy metals extracted from the sterile, by the main species of spontaneuse plants, determined as prevailing on the waste dumps from Moldova Noua. Dominance of plant species ponds was determined using the method developed by Braun-Blanquet (1964) and followed for two years. The method of atomic absorption spectrophotometry at different wavelengths each chemical element was determined in part extracted from samples of dried herbs. The results confirmed that species Salsola kali, Festuca arundinaceea, Medicago falcata and Phragmites australis are the most tolerant plants to heavy metals, long resisted the sterile. Also, Festuca arundinaceea proved plant hiperacumulatoare the lead, Medicago falcata and sterile extract a large number of heavy metals, including manganese, zinc, iron, cadmium, copper and lead in significant amounts. |
