“…They range from 0.4 for E1 and α-E2 to about 1.0 ng/L for EE2 in surface and effluent waters, and from 0.8 for α-E2 to 3.0 ng/L for EE2 in influent waters, which is quite satisfying regarding the LQ reported in the literature. Indeed, in their review, Gabet et al [7] reported LD (corresponding to LQ/3) in the order of 1 ng/L in wastewater, from 1 to 7 ng/L in influent, from 0.1 to 2.4 ng/L in effluent, and under 1 ng/L in surface water.…”

“…Since 2001, 4 reviews [4][5][6][7] and at least 20 papers have been devoted to the development and validation of analytical protocols for estrogens in aqueous samples [e.g. [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…These samples are mostly analysed by liquid or gas chromatography coupled with tandem mass spectrometry (LC-MS/MS or GC-MS/MS). However, the use of the term "method validation" is often abusive [7].…”

Trends in Analytical Chemistry, Elsevier, 2009, 28 (2) AbstractEstrogens act as endocrine disruptors and are known to be discharged in the aquatic environment via effluents from wastewater treatment plants. Efficient analytical protocols are needed to identify and quantify estrogens in wastewaters and aquatic environments in order to study their sources, levels of exposure and modes of transfer. We developed and validated a new analytical method for estrogens in water. It allows to quantify five estrogenic hormones and their conjugated forms at the ng/L level in rivers, wastewater treatment plant influents and effluents, with a satisfying precision (relative standard deviation of within-day analytical recoveries usually lower than 22%). The method was statistically proven to be specific, thanks to the use of perdeuterated hormones as internal surrogates, which proved to be an efficient means to correct for matrix effects.

The detection of organic micropollutants, such as endocrine-disrupting compounds, pharmaceuticals and personal care products, in wastewater and the aquatic environment has brought increasing concern over their potential adverse ecological and human impacts. These compounds are generally present at trace levels (ng l −1 ) and in complex water matrices, such as wastewaters and surface waters, making their analysis difficult. Currently, no standardized analytical methods are available for the analysis of organic micropollutants in environmental waters. Owing to the diversity of physico-chemical properties exhibited by the various classes of organic micropollutants, the majority of established analytical methods described in the literature focus on a specific class of compounds, with few methods applicable to multi-class compound analysis. As such, analytical challenges and limitations contribute to the lack of understanding of the effectiveness of drinking water and wastewater treatment processes to remove organic micropollutants. This paper provides a practical overview of current analytical methods that have been developed for the analysis of multiple classes of organic micropollutants from various water matrices and describes the challenges and limitations associated with the development of these methods.
