The presence of heavy metals (metals with a density of over than 5 g cm-3) in the soil surfaces, are mainly due to industrial and mining activities, fuel combustion, etc. Although some of the metals are essential elements for plants, in the high concentrations have toxic effects on plants. Some of the plants those grown in mining areas are resistant to high concentration of heavy metals. The aim of this study was to assess the iron resistance of plant species in Esteghlale-e- Abadehe fire clay mine. Therefore, soil samples from six mine area and a control were collected. Plant species were collected too. After sampling and preparation of samples parameters: acidity, electrical conductivity, exchangeable and total iron of soil samples and plant iron content was determined. The results showed that exchangeable and total amounts of iron in mining areas were significantly higher than compared amounts in control site. It can be concluded from analyses of plant shoot iron concentrations that some of the plant species of mine areas are resistant to iron stress and use either avoidance or tolerance strategy for the resistance.
