LightLine Technologies proposes to develop a highly sensitive fiberoptic personal monitoirng device similar to a sampling badge, targeted for the simple and conventional measurement of total isocyanate and diisocyanate (I&DCY) airbourne exposure. With verymodest smapling processing (controlled heating) sensing of all types of I&DCYs will be possige and is the ptimary goal of this program. Ths sa ...

Electoronic waste (e-waste) is one of the most rapidly growing waste problems worldwide. Improper handling of e-waste results in vast amounts of toxic waste being sent to landfill and leaching into the water supply. Due to these concerns e-waste recycling is a rapidly growing industry. Unfortunately, most current e-waste recycling processes rely on either manual hand sorting or differental dens ...

The overall goal of this proposed program (through Phase III) is to provide the EPA with a chemical sensor thatn can be multiplerxed into water distributon systems to provide early warning of poisoned water supples. This will be accomplished by developing surface-enhanced Raman (SER) sensors than can be integrated into water supply systems and coupled to a central Paman analyzer via fiber optics. ...

Major improvements in process control, compliance monitoring, and environmental decisionmaking could be made if more accurate, less costly, more rugged techniques were available for continuous monitoring of multiple gas phase pollutants. As part of the solution, Fourier Transform Infrared (FT-IR) spectroscopy is emerging as a promising Field Analytical Method (FAM) for multiple gas monitoring. H ...

Infrared tunable diode laser spectrometers provide a highly effective means of measuring trace concentrations, with either remote sensing or with advective sampling. It is often desirable to measure more than one trace gas at a time. This is especially true when gas emissions are strongly correlated, such as in combustion emissions where measuring both the CO2 concentration and another minor con ...

This Phase I project will investigate using scrap tires to form a protective system for mitigating local scour around bridge piers. Local scour is the erosion of the riverbed around bridge piers, which is induced by the recirculating juncture flow at the intersection of the pier and the riverbed. Bridge failure caused by this phenomenon has long been an important issue with respect to both publi ...

The Clean Air Act of 1990 has raised the concern over trace concentrations of metals in flue gas from electrical generation plants, municipal waste incinerators, and heavy industrial plants. Monitoring will be required to determine the environmental impact and offers an opportunity to empirically minimize it. In flue gas, metals are found in both the vapor state and condensed on fly ash. For sp ...
