Analysis of Factors Influencing Plant–Microbe Combined Remediation of Soil Contaminated by Polycyclic Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) are frequently detected in soil. Their biological toxicity and carcinogenic, teratogenic, mutagenic effects pose a great threat to the ecological environment human health. Firstly, sources, physicochemical properties, environmental hazards of PAHs reviewed this paper, then their pollution status different methods for detection soil described detail. The remediation technologies treat field farmland compared, technical factors influencing phytomicrobial contaminated evaluated most comprehensive way. mechanisms PAHs-contaminated under conditions innovatively discussed. Additionally, regulation mechanism enzymes involved plant microbial degradation soils is studied. This first study on enzyme review. aim paper review status, technologies, mechanisms, biodegradation actions creatively provides reliable support strengthening management.
