Risk assessment models indicate that stream ecosystems receiving municipal wastewater effluent may have the greatest potential for exposure to manufactured nanoparticles. We determined the fate of cerium oxide (CeO2) nanoparticles in outdoor stream mesocosms using 1) one‐time pulse addition of CeO2 nanoparticles, representative of accidental ...
We test the reliability of an inverse model to estimate the amount of mass released instantaneously by a source of pollutant in a turbulent boundary layer. ...
The potential for accidental release of toxic chemicals to the environment is a daily threat for many industrial facilities and plants. ...
In addition, ammonia aqueous solutions are applied by paper mills in various processes. An evaporation model including both heat and mass transfer for aqueous solutions has been developed to quantify chemical evaporation rates. Chemical and physical properties for chlorine dioxide and ammonia aqueous solutions have been analyzed to allow plants to perform a dynamic analysis for ...
Solid sorbents can also be used in a similar process, but have the potential to drastically reduce the energy required to release the CO2 during material regeneration. Through a DOE Cooperative Agreement with supplemental funding from EPRI and industry ADA Environmental Solutions is conducting a viability assessment of solid sorbents for post-combustion CO2 capture. ...
For over 25 years, BREEZE Software has developed a wide range of applications including air dispersion, accidental release, and explosion safety assessment models. In addition to the BREEZE product line, the development staff evaluates, develops, and adapts dispersion modeling algorithms for specific needs and builds custom ...
This paper is focused on the testing of a methodology developed for nuclear risk and vulnerability assessment, and probabilistic evaluation of the long-term atmospheric transport and deposition patterns for radioactive pollutants from selected nuclear risk sites in the Euro-Arctic region. A combination of models (3-D trajectory, DERMA, and HIRLAM) was used to simulate such ...
The DETRACT computational system, consisting of a meteorological processor and a Lagrangian particles atmospheric dispersion model, is applied to the 'Hanford Purex Scenario' – an accidental 3 1/2 days of lasting release of radioactive 131I from the stack of the Hanford (USA) Purex Chemical Separations Plant (2–5 September 1963) – for evaluation ...
Many dispersion models (e.g., DEGADIS, SLAB, INPUFF, or ALOHA) are available and designed to perform the dispersion analyses for different accidental releases. However, choosing a proper dispersion model for an industrial accidental release is not a straightforward process. ...

Dispersion models play an important role in the industrial and regulatory communities. ...
Title III of the Clean Air Act Amendments (CAAA) of 1990 requires establishing regulations to prevent the accidental release and to minimize the consequence of any such release of chemicals listed under 40 CFR Part 68. ...
