Soils have a critical role in global carbon (C) cycling, containing one of the largest fast-cycling carbon stocks on earth. Robust representation of soil organic matter dynamics in Earth System Models is critical for future climate prediction. Current C cycling models assume that all C cycling in non-hydric (i.e. ‘upland’)...
The purpose of this study was to apply the Combined Index (Con, a hazard screening tool, developed by Dr. Debra Forman of EPA Region III Office of Air Radiation and Toxics Division, to the 1994 and 1995 Oregon Toxic Chemical Release Inventory (TRI) for pollution prevention and facility targeting analysis....
This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...
