“…These limits are 0.035 ng/L for EE2 and 0.4 ng/L for E2 (European Parliament 2015). These contaminants in an average equipped laboratory using multiresidue analysis without derivatization can only be determined with poor LOQ values (Liu et al 2011b, Loos et al 2010, Ripolles et al 2014). Our methodology with dansyl derivatization is cheap, quick and simple enough to be considered for use in monitoring studies in the future.…”

“…Full MS and targeted MS/MS methods without derivatization, which are generally used in environmental monitoring applications, detect 40-100 or even more target compounds. These screening methods however often do not include or cannot detect E2 and EE2 due to poor detection limits (Chitescu et al 2015, Kuster et al 2008, Liu et al 2011b, Loos et al 2010. Evaluation of derivatives of estrogens makes positive mode electrospray ionization (ESI) mass spectrometric detection possible and improves generally the sensitivity of MS methods (Anari et al 2002, Xu &Spink 2008.…”

17β-estradiol (E2) and 17α-ethinyl estradiol (EE2), which are environmental estrogens have been determined with LC-MS in freshwater. Their sensitive analysis needs derivatisation and therefore is very hard to achieve in multiresidue screening. We analysed samples from all the large and some small rivers (River Danube, Drava, Mur, Sava, Tisza and Zala) of the Carpathian Basin and from Lake Balaton. Freshwater was extracted on solid phase and derivatised using dansyl-chloride. Separation was performed on a Kinetex XB-C18 column. Detection was achieved with a benchtop orbitrap mass spectrometer using targeted MS analysis for quantification. Limits of quantification were 0.05 ng/L (MS1) and 0.1 ng/L (MS/MS) for E2, and 0.001 ng/L (MS1) and 0.2 ng/L (MS/MS) for EE2. River samples contained n.d.-5.2 ng/L E2 and n.d.-0.68 ng/L EE2. Average levels of E2 and EE2 were 0.61 and 0.084 ng/L respectively in rivers, water courses and Lake Balaton together, but not counting city canal water. EE2 was less abundant, but it was still present in almost all of the samples. In beach water samples from Lake Balaton we measured 0.076-0.233 E2 and n.d.-0.133 EE2. A relative high amount of EE2 was found in river Zala (0.68 ng/L) and in Hévíz-Páhoki canal (0.52 ng/L), which are both in the catchment area of Lake Balaton (Hungary). HighlightsMethod is proposed for simultaneous determination of 17β-estradiol and 17α-ethinyl estradiol. Derivatization is necessary to reach low LOQ. Low ng/L presence of estrogens in selected European Rivers has been detected.

“…The extraction and instrumental analysis followed the authors' previous methods. [22][23][24][25] In brief, the collected water samples (1 L each) from the STP and the laboratory experiment were ltered through prebaked glass ber lters (GF/F, Whatman 0.45 mm pore-size) before extraction. Then 50 mL methanol and 200 mL 4 M H 2 SO 4 were added immediately to each 1 L bottle to adjust the pH to 3.0.…”

Batch experiments were carried out for 7 days to investigate the simultaneous removal of various organic and inorganic contaminants including total nitrogen (TN), total phosphorus (TP), metals, pharmaceuticals and personal care products (PPCPs), endocrine disrupting chemicals (EDCs), and estrogenic activity in wastewater by four freshwater green microalgae species, Chlamydomonas reinhardtii, Scenedesmus obliquus, Chlorella pyrenoidosa and Chlorella vulgaris. After treatment for 7 days, 76.7-92.3% of TN, and 67.5-82.2% of TP were removed by these four algae species. The removal of metals from wastewater by the four algae species varied among the metal species. These four algae species could remove most of the metals efficiently (>40% removal), but showed low efficiencies in removing Pb, Ni and Co. The four algae species were also found to be efficient in removing most of the selected organic compounds with >50% removal, and the estrogenic activity with removal efficiencies ranging from 46.2 to 81.1% from the wastewater. Therefore, algae could be harnessed to simultaneously remove various contaminants in wastewater. Environmental impactDomestic wastewater contains various inorganic and organic contaminants, which could pose risks to the environment and public health. To avoid these adverse effects, wastewater must be treated prior to its nal discharge into the receiving environment. Unfortunately, incomplete removals have oen been reported for these contaminants in wastewater by conventional wastewater treatment technologies. The use of microalgae in the treatment of wastewater has gained great interest over the past few years. However, previous studies on wastewater treatment by algae have been limited and most of them are focused on the removal of inorganic or organic pollutants in articial wastewaters. This study investigated the simultaneous removal capacity of inorganic (nitrogen, phosphorus and metals) and organic pollutants (PPCPs and EDCs) by four freshwater microalgae, and also evaluated the elimination of estrogenic activity in the wastewater by these algae species. The results demonstrated that simultaneous removal of various contaminants in wastewater was achieved, which showed potential application of these algae species in the wastewater treatment.
