What is it about?

Study of how chemical exposure impacts aquatic plants, specifically using electron paramagnetic resonance (EPR) and spin trap methods to detect radical oxygen species (ROS). Pistia stratiotes (water lettuce) was investigated when exposed to salicylic acid and methyl jasmonate. Fenton chemistry is also used as a control. MATLAB simulations also demonstrate that spectra imperfections can be characterized.

Why is it important?

EPR is a valuable analytic technique for ROS characterization. Plants and root cultures are a common means to produce natural products including therapeutic agents. Further, this study is an example of how to explore specific chemical mechanisms related to aquatic phytoremediation.


Even though the common use of aquatic plants are used as 'water ornaments' or weeds, it appears that there are secondary metabolites or metabolic pathways that could be researched to provide for value added molecules or medicines.
