Bioremediation of Polluted Soils contain Phenanthrene and Pyrene with Poultry Litter

One of the most common contaminants found in the soil، are polycyclic aromatic hydrocarbons. Because these compounds are widely distributed in the environment، carcinogenic and cause fetal abnormalities are of particular importance. Based on a comparison of different methods، biological methods of soil improvement options، cost-effective and superior. In addition to choosing the best method، other factors with the affect on the high efficiency on the method، also must be examined. In addition to the litter of bioremediation is effective microorganisms، nutrients can also be required to recultivate the soil، provide.. In this paper، citing previous methods of bioremediation on polycyclic aromatic hydrocarbons in recent years، the importance of soil in the living all organisms and also using the power of the bacteria in fertilizer avian the method of the composition of the soils application phenanthrene and pyrene were reviewed.
