“…However Ball et al [173] indicates that halogenated OPE which can be formed as a result of the chlorination of sewage inhibited a methanogenie consortium at a concentration of 60 ppm. They also report on the aerobic and anaerobie degradation of OPE and halogenated OPEs.…”

“…In an aquatic system, given the linear relationship between log Kow and the organic carbon-water partition coefficient (log Koc), ionic constituents of the water column control the partitioning chemicals into sediment, thereby influencing bioavailability (Erickson et al 2008 (Erickson et al 2008). Another major factor contributing to the environmental fate and persistence of estrogenic chemicals is the minimal or even lack of biodegradation in the anaerobic sediments (Ball et al 1989). These factors point to the relevance of investigating multiple exposure scenarios, for instance active foraging in sediment by animals, rather than limiting investigation to water-borne exposures only.…”

To assess xenoestrogenicity, the 20 days-post-fertilization zebrafish (20dpfZF) life-stage was experimentally exposed to known model chemicals as well as to environmentally contaminated samples. From a selection of key responsive genes, molecular responses associated with the steroidogenic impact (brain aromatase, cyp19a1b and vitellogenin isoform 1, vtg1) were used to assess the endocrinic modulation by xenoestrogenic samples. This work showed diverse in vivo responses by the 20dpfZF, from pure chemicals (bisphenol A, BPA; 17 -ethinylestradiol, EE2; nonylphenol, NP; octylphenol, OP), and their mixture combinations, and to industrially contaminated sediment samples. Gene expression analysis of cyp19a1b and vtg1 in exposed 20dpfZF showed the estrogenic potencies of chemicals in the order: EE2 > OP > BPA > NP. Transcriptional up-regulation of vtg1 in early juvenile fish exposed to mixtures (BPA + NP + OP), relative to individual concentrations, suggest in minimum the additive in vivo effect of a mixture of very low sublethal doses of single xenoestrogens. Complementary expression of cyp19a1b and vtg1 in 20dpfZF, exposed to artificially-spiked sediment with EE2 established the estrogenresponsiveness of the model. In contrast, the lack of simple estrogenic or antiestrogenic trait of correspondence in biomarker transcription was evident from exposure to two types of industrially contaminated sediments, suggesting common non-linearity of in vivo response by the model. The results also highlight the applicability of 20dpfZF in the assessment of remediation and monitoring of historically polluted sites. This study showed that the 20dpfZF addressed the regulatory requirement of a multi-purpose and cost-effective ecotoxicological model capable of in vivo genomic assessment of endocrineactive substances in aquatic samples.

“…Fewer studies have focused on OPEOn than on NPEOn. Two studies showed that OPEOn underwent degradation similar to NPEOn under aerobic and anaerobic conditions of wastewater treatment 3) and in an upflow anoxic sludge blanket reactor 16) . Some pure culture studies have been also conducted on the degradation of OPEO n by specific bacteria 6,7,27,28) .…”

Isolation of Octylphenol Polyethoxylate-Degrading Soil Bacteria: a Long-Term Soil Column Study

et al. 2007

A soil column was percolated with Triton X-100 (octylphenol polyethoxylates; OPEOn) under aerobic conditions for 300 days and OPEOn-degrading bacteria were isolated and characterized phylogenetically. Populations of total culturable bacteria and OPEOn (1000 mg L −1 )-resistant bacteria increased 10 times and 46 times, respectively, during the percolation. 16S rRNA gene sequencing of 128 OPEOn-resistant isolates revealed an increase in the population level of Alphaproteobacteria and decreases in levels of Betaproteobacteria and Actinobacteria with the exposure to the compound. Four OPEOn-degrading strains were isolated and characterized as being related to Bradyrhizobium liaoningense (3 strains) and Afipia sp. (1 strain).
