If K is adiabatic, a molecule containing total vibrational-rotational energy E and, in a particular J, K level, has a vibrational density of states p[E - EjiJ,K). Similarly, the transition state s sum of states for the same E,J, and Kis [ -Eq-Ef(J,K)]. The RRKM rate constant for the Kadiabatic model is... [Pg.1019]

With this mobile phase colour compounds and carotenoids separated with 15 ml of chloroform (first fraction) and the second fraction with 20ml chloroform contained total petroleum hydrocarbons. At the end Spectrofluorophotometry was employed for quantification of analytes. [Pg.270]

Total cyanide concentrations in ground water samples ranged from over 300 parts per million (ppm) at the plant site to about 1 5 ppm at a spring located along the banks of the Little Spokane River Wells used for drinking water, irrigation, and livestock purposes contained total cyanide concentrations as high as 23 ppm ... [Pg.17]

The human body is approximately eighteen percent carbon by weight. That means 18 pounds of a hundred-pound person are carbon. If you weigh 100 pounds, the carbon, hydrogen, and oxygen that you contain total 93 pounds. Only seven of the total 100 pounds are made up of other elements. [Pg.32]

All but the most heavily contaminated fresh and marine waters contain total PAH concentrations in the part-per-trillion or low part-per-billion range (Table 25.3) (Neff 1982b). A large proportion of the PAH content in water is probably adsorbed onto suspended solids (Harrison et al. 1975). In Lake Michigan, concentrations of total PAHs in the surface microlayer varied from 0.15 to 0.45 pg/L, representing on a relative scale, 106 times the concentration in air, suggesting that aerosols are a major source of these compounds and that the microlayer is a repository until the PAHs are removed by adsorption and sedimentation (Strand and Andren 1980). [Pg.1353]

Absorption through the udder is moderate after intramammary administration of radiolabeled cephacetrile to cows, 54.6% of the dose was recovered in milk, 21% in urine and feces, and only 2.55 in tissues within 5 days. At 5 days posttreatment, kidney, udder, and liver contained total drug-related residues equivalent to 232, 227, and 33 ppb of cephacetrile, respectively. When lactating cows were treated with 250 mg intramammary cephacetrile/quarter twice at an interval of 24 h, mean residue concentrations in milk were 14257, 1860, 208, 20, and less than 5 ppb at the first, second, fifth, seventh, and ninth milking postdosing, respectively. [Pg.54]

Following intramuscular administration of 3.5 mg radiolabeled diminazene/ kg bw in cattle, the metabolites p-aminobenzamidine andp-aminobenzamide were found in the urine besides the parent drug these metabolites constituted 22% and 4% of the total radioactivity, respectively. Liver, kidney, and muscle tissues were found to contain total residue levels of 75, 55, and 2.5 ppm diminazene equivalents, respectively, at 7 days postdosing, declining to 24, 12, and 1 ppm, respectively, at 20 day postdosing. [Pg.174]

A Total Diet Study carried out in the UK in 1993 detected low levels of a range of individual phthalates in composite samples of carcass meat, poultry, eggs and milk.69 Only low levels (generally < 0.07 mg/kg) were found. Total phthalate was determined (by conversion of any phthalate in the samples to dimethyl phthalate) in carcass meat, eggs, meat products, offals, poultry, fish, fats and oils, milk and milk products. Each food group was found to contain total phthalate in a range between 0.5 and 8.8 mg/kg. This difference may be due to the presence of phthalate monoester metabolites, which would be included in the analytes. The dietary exposures of even 97.5th percentile consumers were estimated to be within the TDIs for DEHP, BBP and DBP. [Pg.185]

CDDs have been found in infant formulas purchased in the United States (Schecter et al. 1989c). The infant formulas were derived from cow s milk or soybeans. In general, both types of infant formula had very low concentrations of CDDs. 2,3,7,8-TCDD and PeCDD were not detected in cow s milk or soybean formula at detection limits ranging from 0.5 to 1.0 ppt. HxCDD was not detected in soybean formula at the same detection limits. Whole and lowfat (2% fat) cow s milk contained total HxCDD at lipid-adjusted concentrations of 3.6 and 3.3 ppt, respectively. Lipid-adjusted levels of HpCDD were found in whole cow s milk formula (6.5 ppt), lowfat (2%) cow s milk formula (8 ppt), and soybean formula (2.3-3.0 ppt). OCDD was the most abundant congener in both cow s milk and soybean formula. Concentrations of OCDD (lipid-adjusted) were as follows cow s milk formula (15 ppt), low fat (2%) cow s milk formula (21 ppt), and soybean formula (21-36 ppt) (Schecter et al. 1989c). [Pg.479]

The data files are ascii text files arranged in columns separated by space, tabs, or commas with header lines. Equilibrium files contain total ligand concentrations in the first column and free ligand concentrations in the second column. Initial velocity files contain substrate concentrations in the first column and initial velocities of duplicate assays in the subsequent columns. Progress curve files contain time in the first column and the measured experimental signal in the second column. [Pg.114]

There are two types of containment total containment, and vapor containment. Irrespective of which type of containment is provided, the containment structure or facility will be equipped with a means of entrapping or detoxifying the evaporated or aerosolized chemical agent by filters, scrubbers, incinerators, or other appropriate means. Total containment and vapor containment are described as follows ... [Pg.240]

The Total Human Exposme Risk DataBase and Advanced Simulation Environment (THERdbASE) is a data/model management system which contains total human exposure information. THERdbASE is a USEPA-sponsored modeling platform which is being developed and upgraded by the Exposure Modeling and Software Engineering Division of InfoScientific, Inc. (Butler and Engelman, 1998). [Pg.232]

Experimental. In order to study the effect of pH and total lead concentration on adsorption, slurries were prepared with pH between 2 and 6 and containing total lead concentrations (ZPb) of 1.0 X 10 and 5.0 X 10 M. These concentrations, while large in comparison to those normally found in natural waters, were used mainly for two reasons. [Pg.248]

While natural waters will certainly not contain total lead or other heavy metal concentrations so large as the 5.0 X 10 M value used here to illustrate the effect of cation adsorption on adsorption potential, sediments in contact with natural waters will undoubtedly have a large fraction of their adsorption sites occupied with major cations such as Ca " ", K ", or Na . The... [Pg.256]
