IN THE U.S. THERE ARE OVER 24,753 ACRES OF CONTAINER-GROWN NURSERY PLANTS. REPORTED ANNUAL RATES OF APPLICATION OF NITROGEN (N) FERTILIZER RANGE FROM 1036 TO 4730 POUNDS OF N PER ACRE. DETERMINATIONS OF THE ENVIRONMENTAL FATE OF THE APPLIED NITROGEN SHOWS THAT ONLY 5-8% OF THE APPLIED NITROGEN IS INCORPORATED INTO THE PLANT. THE U.S. ANNUAL PRODUCTION OF 24,753 ACRES OF CONTAINER-GROWN WOODY NURSE ...

Not Available Concern regarding debris is expressed in subtopic 19.05 regarding processes, mitigation, and survival of spacecraft in the orbital environment. An important tool in understanding the debris hazard is modeling of the environment to characterize risk. There

The adverse effects of stormwater runoff on water quality in the United States have become an increasing concern in recent years. In 1996, the U.S. Environmental Protection Agency reported to Congress that urban runoff was the leading source of pollutants that cause water quality impairment related to human activities in ocean shoreline waters, and the second leading source of pollutants in estua ...

The proposed Phase I SBIR research is expected to lead to the development of a low cost portable instrument capable of making real time measurements of phosphate in water and soil samples. The sensor system for this instrument will be based on the highly selective phosphate binding properties of a co-polymer to be synthesized in this research. In many areas, the rapid growth and intensification ...

THE PROPOSED RESEARCH WILL DEVELOP AN IN SITU PROCESS WHICH WILL ENHANCE THE RATE AND EFFICIENCY ASSOCIATED WITH THE BIODEGRADATION OF HYDROPHOBIC ORGANIC CHEMICALS AT MILITARY INSTALLATIONS AND SUPERFUND SITES. RESEARCH ACTIVITIES WILLFOCUS ON IDENTIFICATION OF CHEMICAL OR BIOLOGICAL EMULSIFIERS (SURFACTANTS) WHICH WILL ENHANCE THE BIO-AVAILABILITY OF SUCH PETROGENIC WASTE AS CREOSOTE, COAL TARS, ...

This Phase I project involves the development of a portable system for the analysis of trace metals in aqueous solutions based on an innovative disposable multi-element nanoband electrode sensor. The system will be capable of real-time detection of a variety of heavy metals in aqueous solutions, including Zn, Cd, Pb, Cr, Cu, and Hg with a 100 ppb detection limit. The system also will be capable ...

WASTE PICKLING LIQUOR IS PRODUCED WHIN ACID IS USED TO RE- MOVED SCALE FROM STEEL PRODUCTS. TYPICALLY IT CONTAINS 10% ACID AND 5% IRON IN THE FORM OF THE FERROUS SALT OF THE ACIDUSED. IT IS PRODUCED IN LARGE QUANTITIES. ITS DISPOSAL IS DIFFICULT AND WILL BECOME MORE SO WHEN THE PLANNED TOTAL BANON ON DEPOSITION OF LIQUIDS IN A LAND DISPOSAL SITES BECOMES EFFECTIVE. AN ELECTROLYTIC PROCESS WILL BE ...

THE CONTAINMENT OF TOXIC MATERIALS ALREADY BURIED IN THE GROUND AND THE CONSTRUCTION OF NEW DISPOSAL SITES ARE DIFFI-CULT TASKS. IN BOTH CASES THERE IS A NEED FOR VERTICAL AND HORIZONTAL BARRIER WALLS IN THE GROUND THAT ARE KNOWN TO BE DIFFICULT AND EXPENSIVE TO CONSTRUCT WITH CURRENTLY-AVAILA- BLE TECHNOLOGIES. FLUIDYNE PROPOSES TO CONSTRUCT SUCH BARRIER WALLS WITH A NOVEL ONE-STEP PROCESS THT IN ...

Not Available NASA has unique data collection requirements to support ground-based testing of rocket engines. Not only is the rapid collection of data important, but the transmission of this information to processing facilities is critical. By combining new electrical interface standards with high speed fiber optic technology, generic transmission systems can be designed which would be capable of ...

The effluents of many industrial processes, as well as surface water and groundwater from historically polluted sites, often contain unacceptably high levels of Hg and other toxic trace metals. Although inorganic Hg itself is not bioaccumulative, it is readily converted to methyl mercury in the ambient environment, and so should be removed before discharge. The U.S. EPA has identified mercury-cont ...
