AIR TOXIC METALS AND THEIR COMPOUNDS ARE PRODUCED FROM THE COMBUSTION OF FOSSIL-FUELS. THE COMBUSTION OF COAL AND FUEL OIL REPRESENTS AN EXTREMELY LARGE CATEGORY OF SOURCE EMISSIONS. RESEARCH IS PROPOSED THAT WILL PROVIDE A MEANS FOR REMOVING THE VOLATILE METAL CONTENT OF FLUE GAS GENERATED FROM POWER AND STEAM GENERATING PLANTS USING ZEOLITIC OR CARBONACEOUS ADSORBENTS. A LABORATORY-SCALE FIXTURE ...

ION EXCHANGE IS AN ATTRACTIVE TECHNOLOGY FOR REMOVAL OF HEAVY METALS FROM WATER AND WASTEWATERS, BUT IT IS COMMONLY FOUND TO BE UNECONOMICAL DUE TO THE HIGH COST OF CHEMICALS AND DISPOSAL OF THE BRINES OR SECONDARY WASTES GENERATED. SEVERAL IMPROVEMENTS TO THIS TECHNOLOGY ARE PROPOSED TO ALLOW ION EXCHANGE TO BE MORE WIDELY APPLIED TO THE REMOVAL OF TOXIC HEAVY METALS AT SUPERFUND SITES AND IN OTH ...

THE FLUOROCARBON INDUSTRY IN THE UNITED STATES CURRENTLY GENERATES OVER 1,200,000 POUNDS OF SPENT ANTIMONY FLUOROCARBON CATALYST ANNUALLY IN PRODUCING 1,190 MILLION POUNDS OF FLUOROCARBONS (CFCS, HCFCS, HFCS). THIS SPENT CATALYST IS A MIXTURE OF HALOGENATED ORGANIC COMPOUNDS (HOCS), ANTIMONY, AND ARSENIC HALIDES. IT IS EXTREMELY HAZARDOUS, TOXIC, AND CORROSIVE. IT CONTAINS AT LEAST EIGHT LISTED "C ...

THE INDIVIDUALS WITH DISABLILTIES EDUCATION ACT REQUIRES TRANSITION PLANNING, RELATED INSTRUCTION AND INTERAGENCY COORDINATION FOR ALL SPECIAL EDUCATION STUDENTS. THE MOVEMENT FROM SCHOOL TO POST-SCHOOL ACTIVITIES IS AN IMPORTANT EVENT IN TERMS OF THE INFORMATION WHICH CAN BE CAPTURED AND ANALYZED. SPECIFICALLY, THE EMPLOYMENT HISTORY OF DISABLED INDIVIDUALS HAS BEEN A CONCERN NOTED IN A NUMBER OF ...

IMPROVED TECHNOLOGY IS NEEDED TO PROVIDE RAPID, INEXPENSIVE, ON-SITE TREATMENT AND CLEANUP OF SOILS CONTAMINATED BY PETROLEUM HYDROCARBONS AND SOLVENTS. TREATED SOILS SHOULD BE SUITABLE FOR REPLACEMENT IN THEIR OWN EXCAVATION, AND THE TREATMENT PROCESS SHOULD NOT GENERATE ANY SECONDARY WASTES. IN ADDITION, TREATMENT TECHNOLOGY SHOULD BE SIMPLE, ROBUST, EFFIENENT, RELIABLE, AND CAPABLE OF TREATING ...

CADMIUM ELECTROPLATING IN CYANIDE BATHS IS OF SIGNIFICANT ENVIRONMENTAL CONCERN. AS A CONSEQUENCE, A UNIQUE DRY PLATING CONCEPT HAS BEEN DEVELOPED. UNLIKE CONVENTIONAL ELECTROPLATING, THIS METHOD WOULD USE NO LIQUID CHEMICALS. THE DRY PLATING CONCEPT UTILIZES A NOVEL VAPOR DEPOSITION TECHNIQUE FOR CADMIUM OR ZINC. TO MINIMIZE OCCUPATIONAL HAZARDS OF TOXIC CADMIUM, AND TO ACCOMPLISH IN SITU CADMIUM ...
