- An evaluation of chemical persistence screening approachesD W Pennington
ORISE, Systems Analysis Branch, NRMRL, US EPA Cincinnati, OH 45220, USA
Chemosphere 44:1589-601. 2001..The guideline values can then be adjusted iteratively to facilitate step-wise or tiered screening. Using this iterative approach in national and international screening initiatives will result in significant time and money savings...
- Relationship of approaches and a tiered methodology for screening chemicals in the context of long-range transportD W Pennington
Chemosphere 44:1617-31. 2001..A three-tiered screening methodology is then proposed. This tiered methodology will result in significant savings in time and money in national and international screening initiatives...

Life Cycle Systems Group, GECOS, ENAC, Ecole Polytechnique Federale de Lausanne, CH 1015 Lausanne, Switzerland
Ecotoxicol Environ Saf 56:238-50. 2003..The 95th percentile confidence interval on the HC5 estimate given only three chronic test results varies from 5 to 8 x 10(8), depending on the estimation method adopted...
- Cyclic exchanges and level of coupling between environmental media: intermedia feedback in multimedia fate modelsM Margni
Laboratory of Ecosystem Management, Swiss Federal Institute of Technology, CH 1015 Lausanne EPFL, Switzerland
Environ Sci Technol 38:5450-7. 2004..It is one of the important criteria to determine to what extent media can be independently modeled...
