“…So far, the main approach for enhancing the bioavailability of HOCs is the use of synthetic or natural surfactants (Walters and Aitken 2001;Mulligan 2005;Zhu and Aitken 2010), which promote the solubility of HOCs and improve the biodegradation process (Zheng et al 2012). …”

Among 348 microbial strains isolated from petroleum hydrocarbon-contaminated soil, five were selected for their ability to produce biosurfactant based on battery of screening assay including hemolytic activity, surface tension reduction, drop collapse assay, emulsification activity, and cell surface hydrophobicity studies. Of these, bacterial isolate DSVP20 was identified as Pseudomonas aeruginosa (NCBI GenBank accession no. GQ865644) based on biochemical characterization and the 16S rDNA analysis, and it was found to be a potential candidate for biosurfactant production. Maximum biosurfactant production recorded by P. aeruginosa DSVP20 was 6.7 g/l after 72 h at 150 rpm and at a temperature of 30 °C. Chromatographic analysis and high-performance liquid chromatography-mass spectrometry (HPLC-MS) revealed that it was a glycolipid in nature which was further confirmed by nuclear magnetic resonance (NMR) spectroscopy. Bioremediation studies using purified biosurfactant showed that P. aeruginosa DSVP20 has the ability to degrade eicosane (97%), pristane (75%), and fluoranthene (47%) when studied at different time intervals for a total of 7 days. The results of this study showed that the P. aeruginosa DSVP20 and/or biosurfactant produced by this isolate have the potential role in bioremediation of petroleum hydrocarbon-contaminated soil.

“…Previous studies have shown that increasing the apparent solubility of organic pollutants, for example, HMX, DDT, in soil solution could consequently enhance their anaerobic degradation by zerovalent iron [7,22] and also anaerobic biodegradation. [23] However, the soil used in this study was a loam soil that contained 23% and 5.3% of clay and organic matter (OM). DDT, a highly hydrophobic compound, was likely strongly adsorbed on the clay and organic matter and therefore dissolution was not readily observed with the Triton X-100.…”

The objective of this study was to quantify the effectiveness of different pretreated iron byproducts from the automotive industry to degrade DDT [(1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane] in aqueous solutions and soil slurry. Iron byproducts from automotive manufacturing were pretreated by three different methods (heating, solvent and 0.5N HCl acid washing) prior to experimentation. All pretreated irons were used at 5% (wt v-1) to treat 0.014 mM (5 mgL-1) of DDT in aqueous solution. Among the pretreated irons, acid pretreated iron results in the fastest destruction rates, with a pseudo first-order degradation rate of 0.364 d-1. By lowering the pH of the DDT aqueous solution from 9 to 3, destruction kinetic rates increase more than 20%. In addition, when DDT-contaminated soil slurry (3.54 mg kg-1) was incubated with 5% (wt v-1) acid-pretreated iron, more than 90% destruction of DDT was observed within 8 weeks. Moreover, DDT destruction kinetics were enhanced when Fe(II), Fe(III) or Al(III) sulfate salts were added to the soil slurry, with the following order of destruction kinetics: Al(III) sulfate > Fe(III) sulfate > Fe(II) sulfate. These results provide proof-of concept that inexpensive iron byproducts of the automotive industry can be used to remediate DDT-contaminated water and soil.

“…Hematite was most effective in oxidizing the chlorophenol. Addition of Brij 30, a nonionic surfactant, was evaluated as a means of enhancing the solublization, potential bioavailability, and anaerobic biodegradability of DDT, DDD and DDE in an aged contaminated soil (Walters and Aitken, 2001). MONITORING A seasonal and spatial study was conducted on pesticide residues in surface waters of the Shinano River in Japan (Tanabe et al, 2001).…”

This review summarizes the most current technical literature dealing with pesticides and herbicides in the environment. Citations included in this review focus primarily on analytical methods, monitoring, fate and transport, transformation, and treatment strategies as related to pesticides and herbicides in soils, sediments, surface water, and groundwater. (2001) describe methods for the extraction of bentazone, dichlorprop, and MCPA from soils of different texture. All methods gave recoveries of greater than 80%. Caldas et al. (2001) propose a new reaction system for the purification and complexation of CS 2 for the determination of dithiocarbamate fungicide residues in food. Vetter et al. (2001) determined the structure of a persistent heptachlorobornane in toxaphene, B7-1000. This structure validates pervious predictions of persistence based on structure-activity relationships, chromatographic properties, and molecular modeling. A semiautomatic multiresidue method based on solid-phase extraction with a silica column was used to determine pesticide residue in lyophilized fruits (Colume et al., 2001). Numerous researchers used liquid chromatographic techniques to analyze for pesticides in various media. Phenyl urea herbicides were determined in water by electrospray quadrupole ion trap liquid chromatography-mass spectrometry (Draper, 2001). Detection limits were established between 8.0 and 36 ng L -1 . Bicchi et al. (2001) reports on an HPLC-UV method for determining daminozide residues in apple pulp. Debrauwer et al. (2001) identified the major metabolites of prochloraz in rainbow trout using liquid chromatography and tandem mass spectrometry. Through this analysis it was determined that trout are able to biotransform prochoraz primarily as glucuronide conjugates. Kontou et al. (2001) developed an HPLC-PDA method for the determination of ethylenethiourea, the main degradation product of the organic Literature Review 2002 ANALYTICAL METHODS Thorstensen and Christiansen
