For the estimation of volatile dialkyl nitrosamines and A-nitrosopiperidine, A-nitrosopyrrolidine and A-nitrosomorpholine, ION sulphuric acid was added to the sample which was then extracted with redistilled dichloromethane. 1.5m sodium hydroxide was added to the combined extract. After separation, the organic layer was dried over sodium sulphate and evaporated to 2.5mL at 46°C on a water bath. Hexane was added, and evaporation continued to about 250pL. Ahquots of 5pL were analysed for volatile nitrosamines using gas chromatography. [Pg.412]

Wallace et al. (1995) and Wallace (2001) have explored this issue in detail, and ScaiUet et al. (1998, 2003) and ScaiUet and Pichavant (2003) have advanced petrological modeUng approaches to circumvent the problem by estimating the volatile contents contained in the vapor phase prior to emption. Another problem with petrological estimates of volatile yields is that they scale linearly with the emption magnitude, which is often only poorly constrained from the rock record. This is especially tme in cases where tephra dispersal is very widespread, perhaps largely at sea, and where substantial burial, erosion or redeposition limit efforts to identify original thicknesses of sediment in the field. [Pg.1406]

The recommended error estimation methods for high volatility compounds from the reference are reviewed in this section of the report after describing the test protocol procedures. A Monte Carlo simulation of experimental results was then performed followed by statistical analyses to determine the distribution and amount of error associated with estimation of volatilization from water for a high volatility compound. [Pg.56]

The opening chapter An introduction to modelling of pollutants in the environment by Trevor M. Letcher demonstrates convincingly that equilibrium concepts and simple models lead to realistic predictions of, for example, the concentration of a polychlorinated biphenyl in the fishes of the St. Lawrence River. Relative solubilities expressed by octanol-water and air-water partition coefficients play a crucial role for estimating the distribution of chemicals in the environment. This is pointed out in the introductory chapter as well as in others such as Estimation of volatilization of organic chemicals from soil by Epaminondas Voutsas. [Pg.474]

Estimates of volatilization rates from stream parameters are also notoriously inaccurate. Moog and Jirka (1995) found that even the best empirical relationships have a 95% confidence interval of greater than a factor of 3. Values of for a given river reach can be measured by conducting a gas tracer study when greater accuracy is desired (Kilpatrick et al., 1989 Hibbs et al., 1998). [Pg.457]
