Investigation of biogeochemical anomalies and interpretation of environmental conditions for Cu,Mn,Zn,Cd and Pb in kazanli{dotless}-mersin area [Kazanli{dotless} - Mersin bölgesinde Cu,Mn,Zn,Cd ve Pb için biyojeokimyasal anomalilerin İncelenmesi ve çevresel ortami{dotless}n yorumlanmasi{dotless}]

In the area of kazanli{dotless} in mersin,greenhouse cultivation and citrus production have been intensively done. there are several pollutant elements used for agriculture in these lands. due to the petroleum filling plants,factories and especially chromium mining,kazanli{dotless}-mersin region has been exposed to the wastes including toxic elements such as cu,zn,mn,cd and pb for the last 25 years. the pollution in the area can be observed as soil,plant,air,ground water,surface water and seawater pollutions. the aim of this study is to investigate the biogeochemical anomalies and interpretation of the environmental conditions. samples of 19 plants types (16 natural,3 plantation type),soil and water (stream,sea,wells) in the study area were systematically collected. the samples were analyzed for their cu,mn,zn,cd,pb contents using atomic absorption spectrometer (aas). the results of chemical analyses of the soil and plant samples have been evaluated statically for 5 elements and a linear relationship between plant and soil has been determined for 3 elements. leaves and twigs of melilotus sp.,leaves of alhagi camelorum,leaves and twigs of xanthium strumarium for cu,leaves of vicetoxicum parviflorum,leaves of melilotus sp.,leaves and twigs of alhagi camelorum,leaves of salsola kali,leaves of arundo donax,leaves and twigs of xanthium strumarium,leaves of eucalyptus grandis for mn,leaves of melilotus sp.,twigs of pancratium and leaves and twigs of arundo donax for zn have been determined as indicator plants. linear relationship between plant types and soil for the element levels of pb and cd is obtained. element contents of plant and soil are above the normal levels for mn and zn. in this respect,plant and soil can be considered as polluted with these heavy metals in kazanli{dotless}- mersin area.
