Study on In Situ Bioremediation of Polycyclic Aromatic Hydrocarbon Contaminated Farmland Soil

To improve phytoremediation efficiency of aged polycyclic aromatic hydrocarbons (PAHs), in-situ experiment was conducted in the Shenfu wastewater irrigation district in northeast China. Several strengthen measures, including microbe agent, farmyard manure, N-fertilizer, fungi, were taken. The results showed strengthen measures increased of PAHs to alfalfa and ryegrass were 46.36% and 51.12%. The removal rate of 35.98% and 37.54% were achieved for the removal to 5-6 rings PAHs. In-situ experiment proved that strengthened phytoremediation didn’t cause the accumulation of PAHs in inside plant bodies, and it could be used in the farm soil contaminated with PAHs.

Microbial Agent

Degradation of polycyclic aromatic hydrocarbons (PAHs) and microbial quantity were investigated in aged PAHs-contaminated soil in a pot experiment with regrass and alfalfa. After 60 days germination the concentration of total PAHs in soil decreased by 37.57% and 38.41% with the treatment of ryegrass-microbe agent and alfalfa-microbe agent. The processes of ryegrass and alfalfa were 18.72% and 19.34%. The root system promoted the quantity of microbe and the microbial agent was benefit for the PAHs degrading microbe. And there was significant positive correlation between the number of PAHs degrading microorganisms and the removal rate of PAHs in the soil.

The Impact

In this communication, we report the straightforward<br>synthesis of unprecedented electron-acceptors based on dicationic P-containing PAHs (Polycyclic Aromatic Hydrocarbons) where two phosphoniums are connected through various PAHs backbones. The impact of pi-extension on both the optical and redox properties is investigated using a joint experimental/theoretical approach.<br>Finally, (spectro)-electrochemical studies prove that these<br>compounds possess three redox states and EPR studies confirms the in situ formation of an organic radical.
