Estimation of Chemicals in the Environment (227)
Problem: Realistic estimates are needed of chemicals in the environment that result from important chemical processes
Project Activity Scope (from Technical Overview Chart): Mechanisms
PNNL Solution:
- Analyze chemical process and identify key effluents and by-products
- Exploit chemical property and stability references
- Estimate or measure chemical properties
- Analyze effluent byproducts and transport in the environment
- Determine environmental stability
- Estimate chemical concentrations
Capabilities Employed to Meet Client Needs: Chemical process analysis; analysis of chemical reactions in the environment including effects of photolysis, hydrolysis, radiolysis, etc.; chemical property measurements; chemical reaction studies in natural environmental conditions; chemical partitioning analysis in the environment; analysis using established chemical fate and transport analysis models and methods including effects of geographical, topographical, and meteorological conditions as needed; estimation of releases & by-products (concentrations, locations, chemical forms, etc.); integration of results to allow comprehensive understanding of effects.
