In order to restore soil polluted by crude oil, soil collected from an oil field located in northeast China were chosen to study in this research, from which three oil degrading bacteria were obtained by means of bacteria screening. We use them ultimately in order to make little damage to the micro-ecological environment. The experimental results indicated that, the degradation rate increases over...
Glyphosate is the herbicide widely used in China. However, little is known on the processes governing the environmental fate of glyphosate in soils and its environmental risk for groundwater. Laboratory experiments were performed to evaluate the degradation, adsorption, and leaching behavior of glyphosate in three agricultural soils with high sand content and different soil organic carbon content...
Two degradation metabolites of benzo(a)pyrene(BaP), cis-BP4,5-dihydrodiol and cis-BP7,8-dihydrodiol, were identified using high performance liquid chromatography (HPLC) with standards. Both BaP and the two metabolites were well-known toxic compounds. The effect of a nonionic surfactant-Tween80 (TW80) on the degradation of the above three compounds by Bacillus-07, in aqueous phase, was studied. The...
Two newly isolated actinomycetes were identified as streptomyces strain F-6 and F-7. Both of them are possessed of laccase activity. Manganese peroxidase activity of strain F-6 is in very high level(1254.5ul-1).Removal of lignin by F-6, F-7 are more than 50% in 12 days. GC-MS analysis showed strain F-6 could convert lignin into phenol and broken phenol compounds. They may co-culturing with white rot...
This overview is illustrative for the state of the art and mainly focuses on the literature for determination arsenic-containing agents and their correlative toxic compounds near decade. Chromatographic and mass spectrometric techniques are primarily used for the identification and quantification of a broad field of arsenic-containing agents in environmental samples and neutralization masses, obtained...
