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 DESTRUCTION OF ORGANIC HAZARDOUS WASTE BY ELECTRIC ARC PYROLYSIS HAS BEEN DEMONSTRATED TO BE TECHNICALLY FEASIBLE BY OTHERS. THE PRINCIPAL PROBLEMS LIE IN (1) THE SHORT LIFEOF THE ELECTRODES (AND RELATED STRUCTURES) DUE TO THE HIGH TEMPERATURES INVOLVED, AND (2) THE RELATIVELY HIGH COST OF THE ELECTRIC POWER NEEDED. APPLIED RESEARCH ASSOCIATES, INC. PROPOSE TO DESTROY ORGANIC HAZARDOUS WASTE B ...

AN ON-GOING THREAT TO THE RESIDUAL LIFETIME AND SAFETY OF BOILING WATER REACTORS (BWRS) IS INTERGRANULAR STRESS CORROSION CRACKING (IGSCC). A COMPONENT OF SPECIAL CONCERN IN THE RECIRCULATION INLET NOZZLE SAFE END (RINSE). FOR EXAMPLE, WITHIN THE LAST 2 YEARS 30 OUT OF 30 RINSES ARE KNOWN TO BE CRACKED AT A 3-UNIT BWR SITE AND IT IS BELIEVED THAT 20 OUT OF 20 RINSES ARE CRACKED AT A 2-UNIT BWR SIT ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

NOX EMISSIONS FROM COMBUSTION PROCESSES ARE A MAJOR CONTRIBUTOR TO ENVIRONMENTAL STRESSES SUCH AS ACID RAIN, VEGETATION DAMAGE, SMOG AND CHANGES IN THE OZONE LAYER. A NUMBER OF STRATEGIES DIRECTED AT REDUCING NOX EMISSIONS WOULD BENEFIT FROM REAL TIME NOX EMISSIONS MEASUREMENT SINCE THIS WOULD ALLOW FEEDBACK CONTROL OF THE PROCESS. CURRENT INSTRUMENTATION ALLOWS COST EFFECTIVE MONITORING OF VERY L ...

A NEW ADSORPTION--CATALYTIC COMBUSTION SYSTEM WITH APPLICATION TO REMOVAL OF VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND COMMERCIAL OPERATIONS ESPECIALLY WHERE LOW CONCENTRATIONS OF VOC ARE PRESENT IN HIGH FLOWS OF OFF-GAS WILL BE INVESTIGATED IN THIS DEMONSTRATION PROGRAM. THIS SYSTEM WILL HAVE THE BENEFITS OF LOW EQUIPMENT COSTS, SIMPLE OPERATION, LOW ENERGY UTILIZATI ...
