Mercury pollution affects the health of human and wildlife populations, but few ecologically sound or cost-effective remedies to mercury contamination of soil and water have been proposed. There is a strong demand for environmentally friendly and inexpensive alternatives to excavation and removal of mercury-contaminated soil and sediment. Applied PhytoGenetics, Inc. (APGEN), in collaboration with ...

"The DNA microarray is a powerful new technology that can be applied to the detection of biological warfare agents. For the detection of multiple agents, tremendous challenges lie ahead for the DNA microarray technology regarding on sensitivity,selectivity, reliability and consistence. The central theme of this proposal is to apply and optimize a newly developed DNA probe: Molecular beacons (MB) ...

Ambient particulate matter (PM) mass exposure is determined by collecting the PM on a sample filter over a period of 24 hours. Because the composition of ambient PM is constantly changing, the PM mass measured using the reference method may not be representative of the PM levels in the atmosphere, primarily due to the loss of collected semi-volatile material that is present in the atmosphere durin ...

Particulate matter (PM) in ambient air is comprised of many chemical species of varying vapor pressures. A direct-mass measurement of PM mass on filters is the basis of regulatory PM reference methods. The loss of semivolatile PM mass collected on filters and filter sampling artifacts can produce nonquantifiable biases in reference method measurements depending on the thermodynamic history of the ...

"The miniaturized spectrometer presented in this proposal is a simple hand-held static Fourier-transform spectrometer for real-time detection and characterization of chemicals in rapidly changing and/or fast moving environments such as chemicals in cloudsand vapor. The core of the system consists of a pair of mirrors and a line scan CCD array. The interferogram is generated in the spatial domain a ...

This composite technology also can provide the chlorine reduction, pesticide removal, and "taste and odor" improvement functions of common activated carbon water filters. Initial testing of composites has indicated that cysts, bacteria, and viruses in drinking water also can be reduced significantly. The technology can easily be scaled, facilitating many different point-of-use (POU) and point-of-e ...

THE CONTROL OF NITROAROMATIC AIR POLLUTANTS BY BIOSCRUBBING WILL BE EVALUATED AS TO THEIR FEASIBILITY AND EFFICIENCY IN BENCH-SCALE EXPERIMENTS. A MICROBIAL CONSORTIUM ENRICHED ON SELECTED NITROAROMATIC AIR POLLUTANTS SUCH AS NITROBENZENE OR NITROTOLUENE WILL BE IMMOBILIZED ON A POROUS SOLID MATRIX PACKED INTO A SCRUBBING COLUMN. MEASURED VOLUMES OF AIR, CONTAINING KNOWN CONCENTRATIONS OF THE NITR ...

DURING THE MID-EIGHTIES, APPROXIMATELY THREE MILLION CHILDRED BETWEEN SIX MONTHS AND FIVE YEARS OLD HAD POISONOUS BLOOD LEAD CONCENTRATIONS DUE TO PAINT. THERE IS RISK FOR ADULTS IN THE PAINT, AUTOMOBILE MANUFACTURING, AND CERAMIC INDUSTRIES. THE NATION COULD SUBSTANTIALLY REDUCE THE INCIDENCE OF LEAD POISONING IF ONE WERE ABLE TO MEASURE LEAD USING A INEXPENSIVE, PORTABLE DEVICE. CURRENT LEAD MEA ...
