The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

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 ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...
