Acrolein has been identified by the U.S. Clean Air Act as a hazardous air pollutant because of its adverse health effect, particularly on respiratory systems. There are both anthropogenic and natural sources of acrolein in the environment. Acrolein is produced by combustion sources (e.g., vehicle exhaust, prescribed agricultural burning, cigarette smoke) and industrial sources, i ...

New engine diesel pollution is addressed in the U.S. Environmental Protection Agency (EPA) Clean Diesel Truck and Buses, low sulfur diesel, and nonroad diesel rules. Unfortunately, slow fleet turnover will extend full implementation. EPA is interested in both retrofit technologies that reduce emissions (particulate matter, volatile organic pollutants, NOx) from diesel sources and new ...

The goal of this Phase I project is to develop a new “Sparker” process for treating organic hazardous contaminants in water and liquid waste, including persistent and bioaccumulative and toxic chemicals (PBTs), and polycyclic aromatic hydrocarbons (PAHs). Sparker technology also has potential for in situ treatment of dense non-aqueous phase liquids (DNAPLs) and sludge. Sparkers a ...

Mercury is a toxic, volatile metal that is used in electrical switches, relays, and motion detectors because of its electrical conductivity, low volatility, and fluid properties over a large temperature range. Mercury is released into the atmosphere during incineration of trash containing discarded electrical switches, relays, and motion detectors and rapidly migrates to the aquatic environme ...

MixZon, Inc., hypothesizes that lightweight infrared (IR) and video cameras mounted on an unmanned tethered helium balloon accessible via a wireless network can remotely sense water quality at site scales. MixZon will demonstrate the technical feasibility of a ground-based network to monitor and control balloon-mounted, IP-enabled wireless IR and video cameras for measurement of the spatial distri ...

Vegetated roofs (ecoroofs) offer diverse benefits, including energy savings and stormwater runoff reductions. Installation of ecoroofs in both new and existing buildings has expanded significantly during the past 5 years, with several local jurisdictions providing incentives for their installation and the Leadership in Energy and Environmental Design green building rating system offering multiple ...

TIAX previously has evaluated the efficacy of polymeric materials in the removal of chemical and biological agents from surfaces. The system previously evaluated showed better than a two-log removal of simulants for both chemical and biological agents. TIAX is proposing under this Phase I SBIR project to broaden significantly the scope of the technology through application of proprietary syste ...

This Phase I SBIR project will support the development of a field-portable instrument for monitoring and controlling hydrogen peroxide (H2O2) concentration during building decontamination after accidental or purposeful exposure to hazardous biological materials. The goal of Phases I through III is to develop a product that enables accurate real-time H2O2 measurements over the concentration range o ...

IN THE LAST TWO YEARS, THERE HAVE BEEN INCREASING CONCERNS ABOUT THE POTENTIALLY LARGE COOLING OF THE LAND SURFACE TEMPERATURE RESULTING FROM THE SOOT AND DUST INJECTED INTO THE ATMOSPHERE BY THE EXPLOSIONS AND SECONDARY FIRES FROM NUCLEAR EXCHANGES, THE SO-CALLED "NUCLEAR WINTER" SCENARIOS. HERE WE ARGUE THAT, IN ADDITION TO DUST AND SOOT, A LARGE NUMBER OF TRACE GASES (NO[X], H[2]0, HC, CH[4]) C ...

The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing “typical day” meteorological data couples innovative search techniques applied to long-range historical ...
