Phytoremediation is a cost-effective and efficient method to clean up organic pollutants in soil using plants. The process involves plants directly absorbing pollutants, breaking them down with plant enzymes, and promoting biodegradation in the soil. Factors like the type of pollutants, environmental conditions, and plant species affect the success of phytoremediation. Adding substances like surfactants can help make pollutants more soluble. Scientists have developed models to predict how pollutants behave in the environment, but more research is needed to improve phytoremediation techniques.
