ABSTRACT: In the area of Kazanlı in Mersin, greenhouse cultivation and citrus production have been intensivelydone. There are several pollutant elements used for agriculture in these lands. Due to the petroleumfilling plants, factories and especially chromium mining, Kazanlı-Mersin Region has been exposed tothe wastes including toxic elements such as Cu, Zn, Mn, Cd and Pb for the last 25 years. The pollutionin the area can be observed as soil, plant, air, ground water, surface water and seawater pollutions. Theaim of this study is to investigate the biogeochemical anomalies and interpretation of the environmentalconditions. 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, Pbcontents using Atomic Absorption Spectrometer (AAS). The results of chemical analyses of the soil andplant samples have been evaluated statically for 5 elements and a linear relationship between plant andsoil 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 Melilotussp., leaves and twigs of Alhagi camelorum, leaves of Salsola kali, leaves of Arundo donax, leaves andtwigs of Xanthium strumarium, leaves of Eucalyptus grandis for Mn, leaves of Melilotus sp., twigs ofPancratium 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. Elementcontents of plant and soil are above the normal levels for Mn and Zn. In this respect, plant and soil can beconsidered as polluted with these heavy metals in Kazanlı- Mersin area.
