The analyses performed under Environmental Fate can be designed to meet US EPA FIFRA and OPPTS 835 Series, OECD, SETAC, and JMAFF guidelines. All work is conducted in compliance with corresponding Good Laboratory Practices (GLP).

These studies are usually conducted with radiolabeled compounds at controlled temperatures and light intensities, and with volatile trapping where applicable and specified in the corresponding guidelines. Reports include reaction rates, partition coefficients, mass balance and identification of degradates.

Experimental Study Descriptions   

• Hydrolysis:  at various pH values and temperatures.

• Photolysis:  with artificial light in sterile buffer and/or natural waters with quantum yield measurement (actinometry), and on soils.

• Metabolism in Soils:  aerobic, anaerobic, aquatic, and soil/sediment systems.

• Soil Sorption and Mobility:  adsorption/desorption and column leaching studies.

• Soil volatility 

• Tobacco Pyrolysis
