Phytoremediation of total petroleum hydrocarbons (TPH) has the potential to be a sustainable waste management technology if it can be proven to be effective in the field. Over the past decade, our laboratory has developed a system which utilizes plant growth promoting rhizobacteria (PGPR) enhanced phytoremediation (PEP) that, following extensive greenhouse testing, was shown to be effective at remediating TPH from soils. This system consists of physical soil manipulation and plant growth following seed inoculation with PGPR.

- PAHs are common environmental pollutants that can absorb UV radiation and cause toxicity through photosensitization and photomodification, affecting organisms under realistic conditions.
- A previously developed quantitative structure-activity relationship (QSAR) model explained the photoinduced toxicity of 16 PAHs in duckweed, L. gibba, and proved predictive for Vibrio fischeri.
- When this model was tested on Daphnia magna, it revealed that a modified photosensitization factor correlated well with toxicity, showing that incorporating both photosensitization and photomodification factors can effectively predict toxicity across different species.
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants known for their photoinduced toxicity. This toxicity may occur through two mechanisms: Photosensitization, and photomodification. Photosensitization generally leads to the production of singlet oxygen, a reactive oxygen species that is highly damaging to biological molecules.
