Background: Benzene has been classified as group 1 human carcinogens in the environment by the International Agency for Research on Cancer (IARC) mainly because of its ability to cause acute myeloid leukemia (AML). This study was conducted to detect any probable association between urban benzene pollution concentration and occurrence of AML in different regions of Tehran.  Methods: In thi...

H A method for detection of aromatic organics in groundwater has been tested. It was found that use of surface-enhanced Raman scattering and an octadecylthiol coating on roughened silver produced a system which could partition the organics out of water into the strongly Raman enhanced region near the silver surface. The selectivity of the method was illustrated with the three isomers of xylene....

A wet scrubbing process coupled with advanced oxidation processes (AOP) has raised great interest for the abatement of volatile organic compounds (VOCs) owing to its strong oxidation capacity and few byproducts. Fenton as an AOP has been widely used in wastewater treatment. However, the dosing method of Fenton reagents is not suitable for the treatment of continuous-flow VOCs waste-gas since H2...

Experimental studies were carried out with a laboratory-scale biotrickling filter to treat a gaseous stream contaminated with benzene, toluene and xylene (BTX) operated in a continuous mode. The biotrickling filter initially acclimatised with toluene was used to treat BTX compound individually at loading rates ranging from 7.2 g/mhr to 62.2 g/mhr, operated in a sequential mode. The results show...

The combination of chemical oxidation methods with biotechnology to removal recalcitrant VOCs is a promising technology. In this paper, the aim was to identify the role of key process parameters and biodegradability of the degradation products using a dielectric barrier discharge (DBD) reactor, which provided the fundamental data to evaluate the possibilities of the combined system. Effects of ...

In this study, B12N12 Nano ring has been selected because it consist of four 6-side rings and polar bonds B-N which in comparison with non-polar bonds C-C, is more suitable for the study of the absorption of other compounds. So reactivity and stability of Benzene alone and in the presence B12N12 nano ring field checked. To determine the non-bonded interaction energies between Benzene and B12N12...
