“…Studies in Japan have estimated losses of NP and OP during secondary sewage treatment at 79-99% and 47-98%, respectively (Isobe et al, 1999). Removal rates of NPEOs as high 93-99% have also been reported for US systems (Naylor, 1995) whilst Ahel et al (1994) calculated that 35-40% NPEOs were removed during treatment in STW along the Glatt river system in Switzerland (with 85% of the released load present as metabolic products). Alkylphenol polyethoxylate concentrations in influent samples from Dutch STW ranged between 2-2300 µg l -1 , compared with 0-15 µg l -1 measured in outfalls, where substantial removal to particulates is confirmed by the relatively high levels (up to 2400 µg g -1 dry weight) found in sediments (de Voogt et al, 1999).…”

“…There are a number of quantitative estimates of this affinity: for example some 60% transfer of NP from water to bed-sediment has been estimated to occur over a 35 km stretch of the River Glatt, Switzerland, through degradation and sediment sorption (Ahel et al, 1994). Observations of the distribution between aqueous and particulate phases in estuaries also hint at the importance of removal processes.…”

Partitioning, bioavailability and effects of oestrogens and xeno-oestrogens in the aquatic environment

et al. 2005

This review provides insights into the distribution and impact of oestrogens and xenooestrogens in the aquatic environment and highlights some significant knowledge gaps in our understanding of endocrine disrupting chemicals. Key areas of uncertainty in the assessment of risk include the role of estuarine sediments in mediating the fate and bioavailability of environmental (xeno)oestrogens (notably their transfer to benthic organisms and estuarine food chains), together with evidence for endocrine disruption in invertebrate populations.Emphasis is placed on using published information to interpret the behaviour and effects of a small number of 'model compounds' thought to contribute to oestrogenic effects in nature; namely, the natural steroid 17β-estradiol (E2) and the synthetic hormone 17α-ethinylestradiol (EE2), together with the alkylphenols octyl-and nonylphenol (OP, NP) as oestrogen mimics. Individual sections of the review are devoted to sources and concentrations of (xeno)oestrogens in waterways, sediment partitioning and persistence, bioaccumulation rates and routes, assays and biomarkers of oestrogenicity, and, finally, a synopsis of reproductive and ecological effects in aquatic species.

“…This is because the effect is dependent upon PCB-induced hypothyroidism preventing the cessation of Sertoli cell division on about day 16 postpartum, an effect that is probably independent of the weak uterotrophic activity seen for PCBs in the 'rat (43). Likewise, the testicular effects reported for BBP (13) are unlikely to be associated mechanistically with its mitogenicity to MCF-7 cells, just as the endocrine toxicities of p,p '-DDE are most probably mediated by its antiandrogenic properties, rather than by its initially defined estrogenic properties (44).…”

“…Nonetheless, the data supporting some of the suspected environmental links are as fragile as those noted by Kavlock et al (8) for human effects. An example of this is provided by the predominant role played by the natural hormones estrone and 17p-estradiol, as opposed to synthetic xenobiotics, in the partial feminization of fish exposed to effluent of some municipal sewage treatment plants in the United Kingdom (11)(12)(13)(14)(15)(16).…”

Rapid regulatory developments in the area of environmental endocrine disruption present a series of potential problems that are identified and illustrated with examples taken from the recent literature. A list of priorities is provided, including the need for additional epidemiological and wildlife studies, the derivation of a coordinated testing strategy, agreement on the toxicities expected of endocrine disrupting agents, and acceptance that whole animal assays will be uniquely critical in this area of toxicology. The intrinsic difficulty of attempting to simultaneously study all aspects of endocrine disruption indicates the need to reduce the scope of the problem, which can be achieved by first studying toxicities mediated by sex hormone receptors.

“…In particular, accumulated OP, OPEO 1 , and OPEO 2 , with their relatively high hydrophobicity in the environment, act as estrogen agonists and androgen antagonists. [1][2][3] Accumulated knowledge of APEO n biodegradation has revealed that there are two biodegradation mechanisms: 1) exo-type shortening of the EO chain accompanied by either oxidation of the EO moiety (oxidative biodegradation) [4][5][6][7][8] ; or 2) nonoxidative hydroxy shift. 9,10) Moreover, environmental elements, such as Mg 2+ , Ca 2+ , and Fe 3+ , signi cantly in uence the nal degradation metabolites.…”

Application of matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry for the identification of alkylphenol polyethoxylate-degrading bacteria in the environment

et al. 2012

In order to clarify the usefulness of the S10-GERMS (S10-spc-alpha operon gene-encoded ribosomal protein mass spectrum) method for the discrimination of microbial isolates from the environment, the isolates with octylphenol polyethoxylate (OPEO n )-degrading capability from several soils in Japan were classi ed into 4 biodegradation patterns based on di erent nal metabolic toxicants. Some isolates were identi ed as genera Chelatococcus and Mesorhizobium which have never been reported as OPEO n -degrading bacteria based on 16S rRNA gene sequences. e ndings from this study demonstrate that the S10-GERMS method successfully discriminates the isolates at the strain level in the genus Pseudomonas. Moreover, this method is better than 16S rRNA gene sequence similarity because it precisely demonstrated that OPEO n -degrading bacteria in the genera Chelatococcus and Mesorhizobium might be new species. e S10-GERMS method is suggested as a useful tool for the discrimination and monitoring of man-made chemical-degrading bacteria isolated from the environment.
