“…Some species are known to have mechanisms, which allow them to maintain their endogenous hormonal levels in the case of exogenous E2 exposure (Janer et al 2005), but a wide range of species are very sensitive to steroid contaminants (Bhandari et al 2015, Huang et al 2015. Bioaccumulation and biotransformation of xenoestrogens, their effects on individual development and alterations in adult behaviours have been reported earlier (Bhandari et al 2015, Huang et al 2015, Liu et al 2011a, Yan et al 2012. Increased hepatic-somatic index and decreased gonadosomatic index have been described in E2 and EE2 treated fishes.…”

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.

“…They also find application as building block chemicals that are used in making fragrances, surfactants, thermoplastic elastomers, antioxidants, adhesives, coatings, carbonless copy-paper and high performance rubber paper [7]. The distribution of nonylphenol in aquatic environment in several rivers in Europe and USA has been reported where it has been found to be mainly concentrated in sediment [3,5,[8][9][10]. Various studies have also confirmed that nonylphenol present risks to aquatic organisms, especially zooplanktons and benthic macro-invertebrates in areas of high chronic exposure to high concentrations [11,12].…”

The continuous uncontrolled discharge of pollutants into aquatic systems in developing countries like Nigeria has prompted a more sensitive assessment of the level of pollutants inhabiting the environment. Sediments and waters of River Ogun and River Ibeche in southwestern part of Nigeria were collected and analysed for 4-t-Octyphenol (4-t-OP), 4-nonylphenol (4-NP) and Bisphenol-A (BPA), that have been shown to possess endocrine-disrupting properties. Prior to analysis by GC-MS technique, targeted compounds were extracted from samples by ultrasonication and liquid-liquid extraction, respectively. Physicochemical properties of the samples such as temperature, pH, total organic carbon and particle size distribution were also determined. 4-NP and 4-t-Op were detected in all the water samples with concentration ranging between 43.9 ng/L -79.4 ng/L and 57.1 ng/L -68.6 ng/L, respectively. No trace of BPA was found in all the water samples collected. However, BPA in sediment samples from both rivers ranged from non detectable to ≤0.4 ng/g, while 4-t-OP and 4-NP were between 2.2 ng/g -24.5 ng/g and 1.1 ng/g -79.4 ng/g, respectively. The presence of these compounds in surface water and sediments may be attributed to the release of pollutants into the studied rivers from both domestic and industrial activities. Further studies are however needed to investigate the potential ecological and health effects of these compounds on aquatic organisms that inhabit the rivers.

“…Odolarekin gertatzen ez den bezala, konposatu kimikoek gibelean metatzeko joera dute [20,39]. Aipatu behar da, pestizida organofosfatatuen kasuan adibidez, sortzen diren metabolitoak jatorrizko pestizidak baino toxikoagoak direla [40]; beraz, oso garrantzitsua da gibelean sor ditzaketen ondorioak aurreikusteko metatzen diren konposatuak aztertzea.…”

Laburpena: Ingurumeneko uretan kutsatzaile organiko desberdinak aurkitzen dira, nahiz eta kontzentrazio baxuetan izan (ng/L mailan). Araztegien irteera korronteak izan ohi dira konposatu horien iturririk nagusietako bat, araztegiek erabiltzen dituzten mekanismoak ez baitira gai kutsatzaileen arazketa osoa burutzeko. Horien artean, konposatu disruptore endokrino (EDC) izenez ezagutzen diren konposatuak aurki daitezke, eta horiek ingurumenean bizi diren espezieetan aldaketa endokrinoak sor ditzakete, nahiz eta EDCak kontzentrazio baxuetan egon. Kalte horien artean, malformazioak, populazioen aldaketak edo intersexualitatea dira nabarmenenak. Hau guztia ikusirik, kimika analitikoaren ikuspuntutik oso garrantzitsua da metodo analitiko sentikorrak garatzea konposatuak ur-eta biota-laginetatik erauzi eta garbitzeko, bai eta konposatuek biotaren atal desberdinetan metatzeko duten joera aztertzeko ere.Hitz gakoak: konposatu disruptore endokrinoak, erauzketa-metodoak, biokontzentrazioa, ur-laginak, biota.Abstract: There are several organic contaminants present in the aquatic environment, even they are find at very low concentrations (ng/L level). The effluents of the wastewater treatment plants (WWTP) can be one of the main sources into the environment, since the mechanism used by the WWTP are not fully efective for the complete removal of the contaminants. Among them, some of them are classified as endocrine disrupting compounds (EDCs) and they can provoke endocrine alterations in the species habiting in the water even they are found at low concentrations. Malformations, a decrease on the polulation or intersexuality are the most significant damages. Thus, the development of highly sensitive analytical methods for the extraction and clean-up of the water and biota samples is vital from an analytical point of view together with the accumulation capacity of the compounds in the different biota compartments.
