Catalysis with phosphorus P(III) compo­unds (phosphorus trichloride and phospho­rous acid) in the acylation of aniline 3=hydroxy=2=naphthoic acid various media (toluene, octane, chlorobenzene, para=­xylene, ortho=xylene, ortho=chlorotoluene, mesitylene, pseudocumene, n.=deсan, ortho= di­chlo­ro­benzene, mixtures ortho=xylene nitrobenzene) upon boiling vigorous distillation water leads to format...

The general framework developed for assessing chemical risks was applied to twelve chemical substances, namely, radon, formaldehyde, dioxins, cadmium, toluene, chlorpyirofs, arsenic, benzene, mercury, xylene, DDT, and chlordane. In the framework, loss of life expectancy (LLE) was adopted as a measure of risks and individual variabilities in exposure, metabolism, and sensitivity were taken into ...

The sensitivity and precision of headspace solid-phase micro extraction (HS-SPME) at an analyte solution temperature (T (as)) of +35 degrees C and a fiber temperature (T (fiber)) of +5 degrees C were compared with those for HS-SPME at T (as) and T (fiber) of -20 degrees C for analysis of the volatile organic compounds benzene, 1,1,1-trichloroethane, trichloroethylene, toluene, o-xylene, ethylbe...

Biological treatment is a cost-effective and environmentally friendly technique for treating toluene. However, this process limited by the type quantity of toluene degraders that can be applied to different environments methods. It feasible solution constructing new genetic engineering organisms degradation through biotechnology. To facilitate manipulation improve gene expression, toluene/o-xyl...

Our work has focused on the determination of physiological traits that may facilitate in situ degradation of xenobiotic compounds by indigenous microorganisms. For this our interests center on the following questions: What are the ambient conditions in a benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated aquifer? What is the behavior of indigenous bacteria under these conditions? Wh...

Land-use regression (LUR) has emerged as a promising technique for air pollution modeling to obtain the spatial distribution of pollutants epidemiological studies. LUR uses traffic, geographic, and monitoring data develop models then predict concentration in same area. To identify nitrogen dioxide (NO2), benzene, toluene, m-p-xylene, we developed Pohang City, one largest industrialized areas Ko...
