ANALYSIS OF HEAVY METALS CONTENT IN PYLAISIELLA MOSS (PYLAISIA POLYANTHA) GROWING IN THE CITY OF ROSTOV-ON-DON

abstract 1061502004 issue 106 pp. 77 – 90 28.02.2015 ru 845
The problem of environmental contamination by heavy metals is significant problem of urbanization. The search of ways of indication heavy metals pollution becomes actual, because of their simplicity and affordability. A widely used test objects for heavy metals pollution indicators are leafy mosses used for bioindication, because they are highly sensitive to any stress factor. The research shows that bioindication with using leafy mosses as test objects is highly effective method definition of heavy metals pollution. Using of bioindication methods are promising techniques for the assessment of the contamination of ecosystems by heavy metals. Through the use of this method, it is possible indication of pollution of the surface layer of air with heavy metals. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems. The accumulation features of heavy metals in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. pylaisiella moss (P. polyantha) accumulates the largest amounts of the following heavy metals: Zn, Cr, Pb, Sr, Ni (Kc to 1.07), and Cu. According to the Kc values, all the studied elements accumulated by pylaisiella moss form the following series of biological uptake: Zn > Pb > Sr > Cr > V > Ni > Cu > Cо. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of heavy metals pollution in different polluted zones
