It is interesting to note that the mandelic acid excreted in human mine after expostrre to ethylbenzene is predominantly the i -enantiomer, in contrast to the 1.2 1 mixture of R- and -mandelic acid excreted after styrene expostrre. Styrene and ethylberrzene share many common metabolic pathways, but there are evident differences in their stereoselectivity between the two compounds and this provides a means for selective monitoring of exposure to these solvents (Drummond et al., 1989 Kom etal, 1992). [Pg.247]

The suitability of DL-FAAS to perform practical analysis was evaluated by the addition of MMT to samples of tap water, gasoline, and human mine (Table 4). Saturated solutions of MMT were prepared to simulate its determination in ground water MMT was added to gasoline at the maximum allowable level in the United States. Urine was selected because of its significance in toxicological studies. For all samples, good agreement was obtained between the measured and spiked values. [Pg.1086]

The United States, involved in space skirmishes off various planets, first requests, then demands the right to mine the Mitro3 in the Terrellen section, especially because the ore has been discovered in uninhabited Terrellen regions. Those deposits are located beneath the Terrellens most sacred grounds, however, and the Terrellens refuse to let humans mine there. [Pg.332]

Higher quality of the resulting patterns The natural capabiUty of human beings to visually recognize patterns and relations can be used and leads to a more effective data mining process. [Pg.475]

The influence of human activities in a stream drainage basin can be relatively simple and direct, as in the disposal of soluble organic and inorganic waste, or more subtie and complex, as in the conversion of prairie or forest land to agricultural use. Such effects can be expected to increase as population density and agricultural, industrial, and mining activities increase. [Pg.204]

The concept of total body burden refers to the way a trace material accumulates in the human system. The components of the body that can store these materials are the blood, urine, soft tissue, hair, teeth, and bone. The blood and mine allow more rapid removal of trace materials than the soft tissue, hair, and bone (5). Accumulation results when trace materials are stored more rapidly than they can be eliminated. It can be reversed when the source of the material is reduced. The body may eliminate the trace material over a period of a few hours to days, or may take much longer— often years. [Pg.101]

An open-pit copper mine. This mine in Bingham Canyon, Utah, is 4 km in diameter and 0.8 km deep. It is the largest human-created hole on Earth. [Pg.540]

The quantification of kinins in human tissues or body fluids has been limited due to the inherent difficulties in accurately measuring the concentration of ephemeral peptides. Today HPLC-based and RIA/capture-ELA measurements are established to determine kinins in human plasma, liquor or mine. Serine protease inhibitors need to be added to prevent rapid degradation of the kinins in vitro during sample preparation. Kinins and their degradation products have been studied in various biological milieus such as plasma/ serum, urine, joint fluids, kidney, lung and skeletal muscle [2]. Under normal conditions, the concentration of kinins in these compartments is extremely low for... [Pg.673]

From the beginnings of ecology as a discipline, the mining industry has been at the center of the battle over preservation versus exploitation. As discussed in the introduction to this chapter, human activities such as mining, power production from fossil fuels and discharges of industrial and municipal wastes not only increase the rate at which metals enter the biosphere but may also drastically alter the speciation of metals from what it would be in the undisturbed geologic cycle. [Pg.405]

As noted earlier, diverse forms of organomercury are released into the environment as a consequence of human activity. Methyl mercury presents a particular case. As a product of the chemical industry, it may be released directly into the environment, or it may be synthesized in the environment from inorganic mercury which, in turn, is released into the environment as a consequence of both natural processes (e.g., weathering of minerals) and human activity (mining, factory effluents, etc.). [Pg.166]
