Sources and amounts

The sources, amounts, and composition of injected hazardous wastes are a matter of record, because the Resource Conservation and Recovery Act (RCRA)5,14 requires hazardous waste to be manifested (i.e., a record noting the generator of the waste, its composition or characteristics, and its volume must follow the waste load from its source to its ultimate disposal site). The sources and amounts of injected hazardous waste can be determined, therefore, based on these records. Table 20.2 shows the estimated volume of deep-well-injected wastes by industrial category.3 More than 11 billion gallons of hazardous waste were injected in 1983. Organic chemicals (51%) and petroleum-refining and petrochemical products (25%) accounted for three-quarters of the volume of injected wastes that... 

Arsenic analysis of Che other waste streams at HP s facility completed the chemical characterization. Results are listed in Table 2.2-1 and illustrated in Figures 2.2-2, 2.2-3 and 2.2-4. Figure 2.2-2 indicates the sources and amounts of the average monthly arsenic weights chat are produced at HP s San Jose facility (Table 2.2-1 data column 2). The most important point here is that nearly all (about 94%) of the arsenic that flows to the HF Treatment System is from the Slurry Recovery process and is essentially all solid GaAs particles. The remainder is entirely soluble arsenic from the cleaning and etching processes. 

As one might expect, accountability is more stringent for substances classified in Schedules I and II. These compounds can be procured only from licensed sources, and amounts are recorded. After a certain period of time, the quantities of drug used, which have been recorded and witnessed in the laboratory notebook are tabulated and compared with amount remaining (unused), and the original amount issued. The balance is usually returned, or destroyed in the presence of an authorized witness. Dilute standard solutions can be purchased, in limited quantities, usually... 

Addition of organic wastes to agricultural soils is becoming a common practice as a waste disposal strategy and to improve the physical and chemical soil properties. However, the use of organic wastes as soil amendments can affect movement of herbicides. The effects on herbicide movement depend on the source and amount of added amendment and the physical and chemical properties of the soil. For instance, although pig manure slurry and cow manure...

Sources and Amounts of Plutonium in the Environment. Since 1945 approximately 3300 kg of plutonium has been injected into the environment, mostly (>90Z) from atmospheric explosions of nuclear weapons. This corresponds to about 380 kCi total alpha radioactivity. The addition to this amount by releases from nuclear power operations is much smaller the major continuing addition is ca. 0.1 kCi per month released to the Irish Sea from the British nuclear reprocessing plant at Windscale. About 2/3 of the plutonium from nuclear explosions would be formed into highfired oxides which would be rather inert chemically. However, the remainder, created during the explosion as single atoms via the U(n, J ) U(28 ) Pu... 

In 1997, the U.S. Environmental Protection Agency (EPA) issued two reports on Hg and its effects on public health to the U.S. Congress. The first of these reports, the Mercury Study Report to Congress (EPA 1997a,b,c), assessed the source and amount of Hg emissions in the United States, the detrimental effects of Hg on humans and wildlife, and the feasibility of control technologies. The second report, the Study of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating Units. Final Report to Congress (EPA 1998), looked specifically at emissions from utility companies and cited Hg as a major contaminant.

Table 19.5 shows the physical effects of short-term exposure to various doses of radiation, and Table 19.6 gives the sources and amounts of the radiation to which a typical person in the United States is exposed each year. Note that natural sources contribute about twice as much as human activities do to the total exposure. However, although the nuclear industry contributes only a small percentage of the total exposure, controversy surrounds nuclear power plants because of their potential for creating radiation hazards. These hazards arise mainly from two sources accidents allowing the release of radioactive materials, and improper disposal of the radioactive products in spent fuel elements. 

Ligand preparation and database maintenance can be divided into several subtopics. Ligands need to be represented as chemical data structures. Some ligands may require multiple structures, with comprehensive representation requiring treatment of chirality and/or tautomerization and/or protonation state(s). Dependent on the intended use ofthe database, each structure may further require elucidation of one or more 3D conformers. Each of the resultant representations may then be annotated with various types of information, for example, conformational energy, MW, purchase or synthesis source, and amount of physical compound available. This body of information must then be stored as completely and as compactly as possible. In this section, we explore and comment on some of these aspects of virtual ligand preparation.

MAJOR SOURCES AND AMOUNTS OF WASTEWATER IN A PRINTED CIRCUIT BOARD FABRICATION FACILITY... 

In Hankensbuettel and Oerrel, water flood had to be initiated very early in the production history. At the beginning of injection, it was necessary to use fresh water. With increasing water production, fresh water was replaced by produced water. Depending upon the source and amount of injected water, the average salinity at the beginning of polymer injection in different units and locations varied widely. With the exception of a small part of one of the units in Hankensbuettel where the salinity was reduced to low values of 5-10 g/1, the salinity level in all other floods was higher than 70 g/1.

Recently, stndies about the incorporation of Si to ceramics and ACs have been serionsly nndertaken by mai r scientists because of the biomimetic effect of Si and the enhanced osteocondnctivity of the material [8], However, appropriate source and amount of Si for implant materials is still not established.
