“…ELISA is a rapid, simple and cost-effective analytical method (Farre et al 2006;Goda et al 2004;Hintemann et al 2006;Hirobe et al 2006;Huang and Sedlak 2001;Suzuki and Maruyama 2006), which are used recently by many authors to detect EDCs at nanograms per liter level in environmental and biological samples (Farre et al 2006;Goda et al 2004;Hintemann et al 2006;Hirobe et al 2006;Huang and Sedlak 2001;Suzuki and Maruyama 2006).…”

“…EE2 showed the highest estrogenic potency of the three estrogens mentioned in in vitro tests (de Mes et al 2005), and their potencies can be expressed as EE2>E2>E1 (Larsson et al 1999). As the release of these three estrogens from humans cannot be discontinued, the estrogens must be removed by treatment (Suzuki and Maruyama 2006). Because of possible ecological effects and increased attention for water reuse schemes, it is important to increase our understanding of the EDC removal capacities of various wastewater treatment systems.…”

“…Although spiking concentrations have varied widely in studies, from below 100 ng/L (Suzuki and Maruyama 2006) to mg/L (Lee and Liu 2002), temperature and microbial biomass have been the dominant factors shown to influence degradation rates while spiking concentration has had little influence on estrogen degradation rates (Li et al 2005;Xu et al 2009). While degradation of estrogens was slower under reduced oxygen conditions, our observed half-lives from 0.7 to 6.3 days do not suggest that any of the estrogens tested would be persistent in the soil environment.…”

Biological degradation rates of estrogen compounds and common pharmaceutical and personal care products (PPCPs) were examined in soils with a long history of exposure to these compounds through wastewater effluent and in soil not previously exposed. Biological degradation rates over 14 days were compared under aerobic and anaerobic conditions. Estrogen compounds including estrone, 17β-estradiol, estriol, and 17α-ethinylestradiol exhibited rapid degradation by soil microorganisms in both aerobic and anaerobic conditions. Rapid degradation rates for estrone, estriol, and 17α-ethinylestradiol occurred in pre-exposed soil under aerobic conditions; half-lives calculated under these conditions were 0.6, 0.7, and 0.8 day, respectively. Unexposed soil showed similar or slightly longer halflives than pre-exposed soil under aerobic conditions. The exception was 17β-estradiol; in all treatments, degradation in unexposed soil resulted in a shorter halflife (2.1 versus 2.3 days). Anaerobic soils exhibited high biological degradation of estrogens as well. Half-lives of all estrogens ranged from 0.7 to 6.3 days in anaerobic soils. Triclosan degraded faster under aerobic conditions with half-lives of 5.9 and 8.9 days in exposed and unexposed soil. Under anaerobic conditions, triclosan half-lives were 15.3 days in unexposed and 28.8 days in exposed soil. Ibuprofen showed the least propensity toward biological degradation than other chemicals tested. Biological degradation of ibuprofen was only observed in unexposed soil; a half-life of 41.2 days was determined under anaerobic conditions and 121.9 days under aerobic conditions. Interestingly, unexposed soil exhibited a greater ability under anaerobic conditions to biologically degrade tested compounds than previously exposed soil.

The approaches to the analysis for estrogen compounds as environmental pollutants are critically reviewed and evaluated on the basis of significant, recent original publications. The importance of sample pretreatment and analyte preconcentration techniques is pointed out, with an emphasis on SPE and on the use of highly selective interactions such as molecular recognition. The hyphenated systems of high-performance gas or liquid chromatography and mass spectrometric techniques are discussed as the basic methods of determination of estrogens in environmental samples. Immunochemical procedures are shown to be useful in semiquantitative screening of estrogen pollutants (e.g. ELISA kits). Classical HPLC and GC with common UV/Vis, fluorescence and electrochemical detection are useful in routine checking on higher pollutant concentrations.
