AGRONOMIC OPTIMIZATION FOR PHYTOREMEDIATION OF POLYCYCLIC AROMATIC HYDROCARBONS
Phytoremediation is a low-cost method of using plants to degrade, volatilize or sequester organic and metal pollutants that has been used in efforts to remediate sites contaminated with polycyclic aromatic hydrocarbon (PAH) refinery wastes. Non-native plant species aggressively degrade contaminants, and support large biomass. However, these plants must be carefully managed, requiring frequent irrigation and fertilization. And, non-native plant species cannot restore the natural ecosystem. These non-native species may actually disturb natural plant succession in polluted sites. Allowing native species to naturally revegetate is an attractive proposition since it saves on the cost of restoration and management. Optimization of agronomic practices at refinery waste disposal sites undergoing such plant-based remediation methods is essential for managing site remediation efforts. This proposal is an innovative effort to optimize these practices critical to cleaning up PAHs from refinery waste disposal sites using native plant species.
