Despite its benefits, this approach also faces several challenges and risks: - Limitations of Microorganisms: Not all microorganisms are effective against every type of hydrocarbon. - Environmental Variables: Temperature, oxygen levels, and nutrient availability can affect the efficiency of bioremediation. - Time-Consuming: The process can be slower compared to other methods. - Potential Risks: The introduction of genetically engineered microorganisms could disrupt local ecosystems if not properly controlled.
