This research will integrate laboratory, model ecosystem, and field studies for the purpose of tracing the signature of organic agrochemicals through the environment. The specific approach involves: 1) developing methods of spectroscopic and mass spectrometric analysis of pyrethroids, 2) probing the direct and indirect sunlight-mediated photolysis of pyrethroids through a combination of kinetic modeling and byproduct analyses, 3) characterizing the chemical constituents of nut hulls as related to sun-light mediated degradation, and 4) relating sunlight-mediated degradation to the relative toxicity of pyrethroids and resulting products.
