Study of the Behaviors of Gunshot Residues from Spent Cartridges by Headspace Solid-Phase Microextraction-Gas Chromatographic Techniques.
J. Forensic Sci. 60 , 869-77, (2015) Gunshot residues, produced after shooting activity, have acquired their importance in analysis due to the notoriety of firearms-related crimes. In this study, solid-phase microextraction was performed to extract the headspace composition of spent cartridges u... |

Synergistic role of different soil components in slow sorption kinetics of polar organic contaminants.
Environ. Pollut. 184 , 123-30, (2014) We observed that the sorption kinetics of nitrobenzene and 2,4-dinitrotoluene (two model polar compounds) was significantly slower than that of 1,4-dichlorobenzene and phenanthrene (two model apolar compounds). The difference was attributable to the strong no... |

The role of black carbon as a catalyst for environmental redox transformation.
Environ. Geochem. Health 34 Suppl 1 , 105-13, (2012) Black carbon (BC) is an important class of geosorbents that control the fate and transport of organic pollutants in soil and sediment. We previously demonstrated a new role of BC as an electron transfer mediator in the abiotic reduction of nitroaromatic and n... |

Directed evolution of the transcriptional regulator DntR: isolation of mutants with improved DNT-response.
PLoS ONE 7 , e29994, (2012) The transcriptional regulator DntR, which previously has been isolated from bacterial strains capable of degrading 2,4-dinitrotoluene (DNT), was engineered in order to improve the ability to detect DNT. A directed evolution strategy was employed, where sequen... |

Evolution of catabolic pathways for synthetic compounds: bacterial pathways for degradation of 2,4-dinitrotoluene and nitrobenzene.
Appl. Microbiol. Biotechnol. 62(2-3) , 110-23, (2003) The pathways for 2,4-dinitrotoluene (2,4-DNT) and nitrobenzene offer fine illustrations of how the ability to assimilate new carbon sources evolves in bacteria. Studies of the degradation pathways provide insight about two principal strategies for overcoming ... |
