The aim of this work was to quantify the most significant impact from the polluted environment and to review the correlation between pollution indicators and the content and structures of Tanacetum vulgare L. (Tansy). Heavy metals as mercury, lead, cadmium, chromium and nickel are considered as pollution indicators. The micro and macro elements concentration of S, P, K, Ca, Mg, Na, Fe, Si, Al and Mn were tested too. The concentration of the essential oil was analyzed as indicator of Tansy environmental adaptability. Essential oils are practically agents which represents correlation between plant and environment. The type of Tansy was selected for laboratory research, because it belongs to most speeded urban flora and vegetation, in which the imperative to adapt is very strong. All those parameters was monitored on two different locations: industrial zone (anthropogenic) and park area (non anthropogenic) for comparison, as zero stage of the environment, before pollution. The diferences were also recorded in the morphological and anatomical structure and chlorophyll a and b content of the Tansy and they were caused by differences of cumulative environmental conditions, with dominant efects of the contamination degree of the location, soil type and microclimate.
