The results of a study on the removal of arsenic (As) contamination in soil using dracaena fragrans. In the research, this plant was planted on as – contaminated soil at five levels of concentration of 0 mg/kg, 100 mg/kg, 200 mg/kg, 300 mg/kg and 500 mg/kg. After 90 days experimental in the five concentrations the survival rate was 100%. However, as concentrations have a significant effect on growth parameters, especially in concentration 500 mg/kg, the growth of the plant showed marked signs of slow growth, the leaves were retracted. Analyzed results on as content in roots, stems, and leaves of plants at all experimental after 90 days show that there was a linear relationship between as content in different parts of the plants and in soil samples. At the experiment concentration 500 mg/kg, the concentration of as in roots was 15.7 mg/kg, that in stems was 4.4 mg/kg and that in leaves was 3.2 mg/kg. The amount of as accumulated in the roots had the highest percentage. There was 1.14 mg as had been removed by 209.1 g of biomass of dracaena fragrans after 90 days.

Environmental pollution due to heavy metals is a matter of great concern to many scientists and managers worldwide. The threats to human health from heavy metals are primarily associated with the exposure in agriculture production activities. However, a considerable number of technological methods have been used to remove the heavy metals from polluted soils. One of the simplest measures to effectively remove heavy metal contamination is to use both plants and microorganisms, which have been considered "natural materials" or "Bio-Materials" to treat pollutants. This study was conducted on assessing the ability of Trichoderma to absorb heavy metals into the plant. Phytoremediation experiments with Trichoderma were used to remove heavy metals in the soil. Our findings showed that Dracaena Fragrans plants are capable of absorbing heavy metals Cu, Pb, and Zn in soil contaminated with experimental heavy metals.
