“…4). The value is much lower than those of some WWTPs effluents in other countries (Cargou t et al 2003;Pawlowski et al 2004;Svenson et al 2003). It can be seen that most of the estrogenic chemicals in the influent were non-polar or moderate polar.…”

Abstract. A battery of in vitro bioassays, including a Neutral Red (NR) assay using MCF-7 cells for predicting cytotoxic chemicals, an ethoxy resorufin-O-deethylase (EROD) activity assay using H4IIE cells to check for dioxin-like chemicals, and a recombinant gene yeast assay for screening estrogenic chemicals, was conducted to assess the removal efficiencies of trace toxic chemicals by different treatment processes in the waste water treatment plant (WWTP). The effluents were extracted by solid phase extraction (SPE) and were fractionated into three fractions based on polarities. The battery of bioassays was performed for each fraction. In the battery, the toxicities of the effluents were described according to their modes of actions (MOA) or biomarkers and the properties of the toxic chemicals were categorized by their polarities and MOAs. The proposed procedure could be used as a tool to diagnose the toxic characteristics of the complicate mixture. The results showed that cytotoxic, dioxin-like and estrogenic chemicals could be detected in all samples. In the influent, cytotoxic and dioxin-like chemicals were mainly in polar fraction and estrogenic chemicals were in non-polar and moderate-polar fractions. The secondary treatment (active sludge) could remove a small amount of these toxicants. Among different types of advanced treatments, flocculation was good enough to remove most of the cytotoxic chemicals and a combination of flocculation, ozone oxidation, and post-biological treatment could eliminate most of the dioxin-like and estrogenic chemicals.

“…This synthetic hormone is of particular concern due to its high persistence in the environment and estrogenic activity. Concentration levels of natural and synthetic estrogens in WWTP influent and effluent has been well documented Andersen et al 2003;Braga et al 2005), but the removal efficiency of natural and synthetic steroid estrogens in WWTPs can be influenced by rainfall (Shore et al 1993;Kirk et al 2002), temperature (Tabak et al 1981;Desbrow et al 1998;Ternes 1998;Belfroid et al 1999;Baronti et al 2000), and hydraulic and sludge retention times (Ternes et al 1999a;Johnson et al 2000;Kirk et al 2002;Andersen et al 2003;Svenson et al 2003;Cargouët et al 2004). Previous research developed a model to estimate influent and effluent concentrations of steroid estrogens at sewage treatment plants (Johnson and Williams 2004); however, due to a lack of correlative information including water flow, population, WWTP operation parameters, and analysis methodology differences, and difficulty in determining steroid estrogens in complex matrices, estimated results have not always agreed with the monitored data.…”

Concern over steroid estrogens has increased rapidly in recent years due to their adverse health effects. Effluent discharge from wastewater treatment plants (WWTPs) is the main pollutant source for environmental water. To understand the pollutant level and fate of steroid estrogens in WWTPs, the occurrence of estrone (E1), 17-β-estradiol (E2), estriol (E3), and 17-β-ethinylestradiol (EE2) was investigated in the Gaobeidian WWTP in Beijing, China. Water samples from influent as well as effluent from second sedimentation tanks and advanced treatment processes were taken monthly during 2006 to 2007. In influent, steroid estrogen concentrations varied from 11.6 to 1.1× 10 2 ng/l, 3.7 to 1.4×10 2 ng/l, no detection (nd) to 7.6×10 2 ng/l and nd to 3.3×10 2 ng/l for E1, E2, E3, and EE2, respectively. Compared with documented values, the higher steroid estrogen concentrations in the WWTP influent may be due to higher population density, higher birthrate, less dilution, and different sampling time. Results revealed that a municipal WWTP with an activated sludge system incorporating anaerobic, anoxic, and aerobic processes could eliminate natural and synthetic estrogens effectively. The mean elimination efficiencies were 83.2%, 96.4%, 98.8%, and 93.0% for E1, E2, E3, and EE2, respectively. The major removal mechanism for natural estrogens and synthetic estrogen EE2 were biodegradation and sorption on the basis of mass balance in water, suspension particles, and sludge. In the WWTP effluent, however, the highest concentrations of E1, E2, E3, and EE2 attained were 74.2, 3.9, 5.1, and 4.6 ng/l, respectively. This is concerning as residual steroid estrogens in WWTP effluent could lead to pollution of the receiving water. Advanced flocculation treatment was applied in the WWTP and transformed the residual estrogen conjugates to free species, which were reduced further by filtration with removal shifting from 32% to 57% for natural estrogen, although no EE2 was removed.

“…Ainsi, il est généralement observé qu'un traitement primaire seul ne permet pas, ou très peu, l'enlèvement des estrogènes des eaux usées, tandis qu'un traitement secondaire à boue activée réduit de manière significative les quantités d'estrogènes (BARONTI et al, 2000;D'ASCENZO et al, 2003;JOHNSON et SUMPTER, 2001;ONDA et al, 2003;SVENSON et al, 2003). D'ailleurs, le TRS semble avoir une influence positive sur la capacité du système à boues activées à éliminer les estrogènes.…”

RésuméDifférents produits chimiques naturels et d’origine industrielle présentent une activité endocrinienne. Ces composés sont susceptibles d’agir sur le système endocrinien des animaux et des êtres humains (altération ou déficiences des fonctions reproductrices, occurrence de tumeurs malignes, etc.). De nos jours, il reste de nombreuses questions en suspens (ampleur de la contamination, devenir dans l’environnement, etc.) et le caractère persistant de ces substances en fait un problème majeur pour les générations futures. De plus, plusieurs études ont montré que les estrogènes naturels (tels que l’estrone, le 17β‑estradiol et l’estriol) et l’estrogène synthétique (17α‑éthinylestradiol) sont les composés les plus oestrogéniques présents dans les effluents de stations de traitement des eaux usées. En conséquence, ces estrogènes peuvent rejoindre les eaux de surfaces et les contaminer. En effet, des concentrations aussi faibles que 0,1 ng/L peuvent provoquer des effets oestrogéniques chez les organismes aquatiques exposés. Cette revue s’est donc concentrée sur la présence de ces types de composé dans les eaux de surface et usées, et plusieurs procédés de traitement sont discutés par rapport à leur capacité d’enlèvement des estrogènes. Ainsi, le traitement primaire seul ne permet pas l’enlèvement des estrogènes des eaux usées, alors qu’un traitement secondaire à boue activée réduit généralement les quantités d’estrogènes. Les procédés dits avancés montrent un potentiel élevé pour l’enlèvement des estrogènes, bien qu’ils peuvent former des sous-produits oestrogéniques et/ou cancérigènes. Finalement, les systèmes enzymatiques pourraient être des procédés innovateurs pour le traitement des estrogènes, puisqu’ils montrent un potentiel élevé pour l’enlèvement des composés aromatiques dans les eaux usées.
