Environmental adaptibility of tansy (Tanacetum vulgare L.)

Ecological role of essential oils is reflected in the interaction of plants with environmental factors. Environmental adaptability of the plants can be assumed from essential oil contents. Essential oils are agents, which communicate with the plant environment. Tansy (Tanacetum vulgare L.) was selected for laboratory research since it belongs to urban flora and vegetation where the imperative to adapt is high. Sample plants were collected from two site locations: Ada Huja (industrial zone) and Topider (greenarea) in Belgrade, Serbia. A GC-MS analyses, to determine quantitative and qualitative composition of essential oils were used. The results of the research indicate that tansy from both locations shows a high degree of adaptability. Tansy from Ada Huja had larger total amount of essential oils comparing to plants from Topider. This study presents the comparative results of laboratory research. Specific components of the essential oil samples of plants from both site locations are identified

Environmental study of heavy metals influence on soil and Tansy (Tanacetum vulgare L.)

The aim of this work was to define the correlation between heavy metal (mercury, lead, cadmium, chrome and nickel) concentration changes (in soil, leaf, stem, root and essential oil in Tansy) and type and distance from source pollution. The concentration was monitored on different locations: 1) Chemical industry panevo (with accident situation); 2) Panevo industrial zone; 3) highway; 4) Ada Ciganlija recreation zone and 5) Topider park. Mercury (Hg) concentration was analyzed as a functionof time, starting from accident situation from 1999 to 2008. Hg had maximum concentration of 131 200 mg/kg at a soil depth of 0 - 15 cm. After three, six and nine years, linear accident Hg concentrations insoil decreased from 85 400 via 41 060 to 106.0 mg/kg. Mercury concentration which results in the location where accident occurred showed that 6 years was necessary for concentration to drop below the limits and for revitalization of standard industrial Tansy vegetation. Concentrations of Hg in the Tansy plants from contaminated site were 5, 10, 100 and 200 times greater than in industrial zone, highway, Ada Ciganlija and Topider, respectively. The highest amount of lead (Pb) was in leaves (14.1mg/kg) and in essential oil (0.7 mg/kg) of Tansy near the highway. However, Pb concentration in soil and plant was decreased with square of highway distance
